LASIK or laser-assisted in situ keratomileusis is a refractive surgery that is used to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism as an alternative to eyeglasses or contact lenses. LASIK is currently the most common of the refractive eye surgeries, largely because of the relatively low risk and the quick recovery and improvement in eyesight.

Also known as laser eye surgery or laser vision correction, LASIK uses a laser to reshape the cornea which is responsible for clear vision. The procedure is quick and relatively painless and eyesight is usually improved to 20/20 vision within one day of the surgery.

How Does LASIK Work?

LASIK is an outpatient procedure, which takes about 15 minutes for the actual surgery on both eyes and an hour total with recovery. A topical anesthetic drop is used and there is no need for bandaging or stitches following the procedure. The doctor will start by stabilizing the eye and then making a small flap in the outer layer of the cornea. Then with access to the underlying tissue, he uses a laser to reshape the corneal tissue and re-closes the flap, which will heal on its own. The nature of the corneal reshaping depends on the type of refractive error.

Wavefront LASIK

Wavefront LASIK uses computer mapping technology to guide the laser treatment based on the precise shape of the cornea. This can correct very precise issues, provide much sharper vision than non-wavefront LASIK and can reduce complications such as halos, glare and problems seeing at night.

What to Expect During and After LASIK?

During the procedure you may feel some pressure on your eye while the laser is working. Immediately following you will likely experience some blurriness and may feel burning or itching (be sure not to rub your eyes!). For your journey home you will be given protective shields to guard your eyes and will need someone to drive you. You will also be prescribed medicated eye drops for a week or so to aid in healing and prevent infection. Your doctor may also recommend artificial tears to moisten the eyes and keep them comfortable in the days following the procedure.

The day after the surgery you will be asked to visit your eye doctor (or the surgeon) for a checkup and to evaluate whether you are able to drive. Most people experience an improvement in vision by then, although for some it can take a few days or even a week. Your eyes may be sensitive to light for a day or two as well. You will likely be advised to rest for a day or two and to refrain from strenuous physical activity for about a week until further healing has taken place.

Most people achieve at least 20/20 vision following the surgery, although this can vary and there are cases where 20/40 vision is obtained or where people continue to wear glasses or contacts with a much lesser prescription. Some patients have light sensitivity, particularly when driving at night, also suffering from seeing halos around lights or glare. There are glasses and lenses available to reduce this glare and assist with night driving.

For some, it can take weeks or even months until the vision completely stabilizes. Occasionally, after a few months, patients who do not experience perfect results will schedule an enhancement or touch up surgery to correct the vision even further.

Am I a Candidate for LASIK?

The ideal LASIK candidate is a patient over 18 with generally healthy eyes. Since the procedure involves shaping the cornea by removing some of the tissue, it is not ideal for individuals with a thin cornea or any sort of corneal condition or disease. Patients with chronic dry eyes might also be disqualified as LASIK can often exacerbate these symptoms.

During a comprehensive eye exam your eye doctor will assess your eligibility by looking at the general health of your eye including your cornea, your pupil, the moisture in your eye, the type of refractive error you have and whether you have any other eye conditions of concern.

For the right candidate, LASIK can offer a lifestyle improvement in giving clear vision without the need for glasses or contact lenses, however, the results are not guaranteed. You and your eye doctor need to weigh the benefits and the potential risks based on your personal needs.

For both adults and children alike, eye exams are an important part of one’s general health maintenance and assessment. Your eyes should be checked regularly to ensure that you are able to see as best as possible. Regular eye health exams will also check for signs of eye disease or conditions that can affect not only your vision but your overall health. Vision and eye health is such a critical part in learning and development, therefore, we highly recommend eye exams for infants and children.

Vision Screening vs. an Eye Exam

When we recommend regular eye exams, this should not be confused with a vision screening. A vision screening is a basic test that indicates if you have difficulty seeing and require further assessment and corrective measures. It can be performed by anyone, whether it is a school nurse, a pediatrician or even a volunteer at a vision clinic. A vision screening usually only checks vision, it does not check eye health. Also, most vision screenings for kids only check for nearsightedness (when you can not see far), but what happens when the majority of children are farsighted? Most of the time many of these kids get overlooked.

A comprehensive eye exam on the other hand, can only be performed by an eye doctor as it requires special knowledge and equipment to look around and into your eye to check your eye and vision health. Such an exam can assess whether there are underlying causes for vision problems and whether there are any signs of disease which can threaten your site and the health of your eye. A comprehensive eye examination can also diagnose symptoms of diabetes, high blood pressure, high cholesterol, tumors, cancer, autoimmune disorders, and thyroid disorders. A comprehensive eye examination will also provide an accurate prescription for eyeglasses or contact lenses.

Eye Exams for Eye Health

Eye exams are critical because many vision threatening eye diseases such as glaucoma, macular degeneration, cataracts, or diabetic retinopathy have no or minimal symptoms until the disease has progressed. In these cases, early detection and treatment is essential to halting or slowing down the progression of the disease and saving eyesight. During a comprehensive eye examination, your eye doctor will be looking for initial signs of these diseases. If a problem with your eyes arises such as red eyes, eye allergies, dry eyes, eye swelling,eye pain, always seek an eye doctor as your first doctor to call since they are specifically trained to treat eye diseases.

Eye Exams and Children

If your child is having developmental delays or trouble in school there could be an underlying vision problem. Proper learning, motor development, reading, and many other skills are dependent upon not only good vision, but your eyes functioning together. Children that have problems with focusing or hand-eye coordination will often experience frustration and may exhibit behavioral problems as well. Often they don’t know that the vision they are experiencing is abnormal so they aren’t able to express that they need help. Many conditions are much easier to treat when they are caught early while the eyes are still developing, so it is important to diagnose any eye health and vision issues as early as possible.

Eye Exams Over 40

Just like the rest of our bodies, our eyes begin to weaken as we age. There are a number of common age-related eye conditions such as presbyopia, cataracts, and age-related macular degeneration that can begin to affect your vision and your daily life. While some of these conditions are more of an inconvenience, others could lead to vision loss and dependency.

In addition to regular yearly eye exams, it is important to be aware of any changes in your eye health and vision. Also know your potential risk factors as well as your family ocular and medical history. Over half of the vision loss worldwide is preventable with proper treatment and care.

For both adults and children, an eye exam is a critical part in maintaining your overall health and well-being, and therefore, regular eye exams should be incorporated into your health routine. Comprehensive eye exams assess your vision and the health of your eye, looking for early signs of disease that may not have obvious symptoms. You should not wait until you experience a vision problem or symptoms of an eye condition to schedule a routine exam.

Depending on your age, family history, general health and eye health, it is recommended to have an eye exam every one to two years. Of course if you experience any serious symptoms that affect your eyes or your vision, you should contact your eye doctor immediately.

The Difference Between an Optometrist (OD) and an Ophthalmologist (MD or DO)

Confusion about the difference between optometrists and ophthalmologists is common, and many people are not aware of how the two eye care professionals differ.

Optometrists

Optometrists or Doctors of Optometry attend optometry school which is usually at least four years of graduate level training. They are able to perform eye exams, provide prescriptions for eyeglasses and contact lenses, and diagnose and treat eye diseases as as glaucoma, dry eyes, or eye infections that may require medication or drops. They can consult with and co-manage patients in pre- or post-op surgical care, however they do not perform surgery.

Ophthalmologists

Ophthalmologists are medical doctors that attend medical school and later specialize in ophthalmology. They are able to do all of the services mentioned above but also perform eye surgeries such as cataract surgery, refractive surgery such as LASIK and deal with more urgent eye conditions such as retinal detachment.

Infant and Child Eye Exams

According to the American Optometric Association (AOA) children should have their eyes examined by an eye doctor at 6 months, 3 years, at the start of school and then at least every 2 years following. If there are any signs that there may be a vision problem or if the child has certain risk factors (such as developmental delays, premature birth, crossed eyes, family history or previous injuries) more frequent exams are recommended. A child that wears eyeglasses or contact lenses should have his or her eyes examined yearly.

Adult Eye Exams

Healthy adults under 40 with good vision and who do not wear eyeglasses or contact lenses are recommended to have an eye exam at least every two years. Those that do use vision correction or have a health issue such as diabetes, high blood pressure or another health condition that can have an impact on your eye health should schedule a yearly exam, unless the eye doctor recommends more frequent visits.

Once you reach 40, you become susceptible to a number of age-related eye conditions such as presbyopia, cataracts or macular degeneration, therefore annual or bi-annual exams are strongly recommended.

As you continue to age, particularly after age 55, the risks of eye disease increase, and early detection can be critical to preventing significant vision loss or blindness. Scheduling a yearly eye exam can make all the difference in maintaining your independence and quality of life.

How to Prepare for Your Exam

Prior to your exam you should decide whether you will be seeking special services such as a contact lens exam or LASIK consultation. These services may cost extra. Check with the doctor’s office or your insurance provider to see if they cover any of the exam expenses.

You need to know if you have medical insurance, vision plan coverage or both. Medical insurance usually does not cover “wellness/refractive” exams for glasses or contact lenses. Vision plans will cover exams for glasses or contacts, but usually cannot be used for red eyes, floaters, or other medical eye health problems. Please bring your insurance cards with you.

In addition to bringing your current pair of glasses or contacts if applicable, it is important to be aware of your personal and family history and to have a list of medications or supplements you are currently taking. Your pupils will probably be dilated as apart of your exam, so plan accordingly.

Your eyes are one of the most complex organs in your body. A comprehensive eye exam to assess your visual system and eye health involves a number of different of tests. Unlike a simple vision screening, which only assesses your vision, a comprehensive eye exam includes a battery of tests in order to do a complete evaluation of the health of your eyes and your vision.

The tests that you will undergo in a comprehensive eye examination may vary from eye doctor to eye doctor but here are are some common exams that you may encounter:

Patient Background and History

One of the most important parts in a comprehensive eye exam is your patient health history. This information will alert your doctor to any conditions that should be monitored closely, such as an allergy to any medications, current or family history of systemic or eye pathology or environmental conditions that could be affecting your vision or eye health. This will also help your doctor to determine any preventative eye care measures that are relevant to keep your eyes healthy for years to come.

Visual Acuity

Visual acuity is a measurement of your vision using an eye chart, the Snellen Eye Chart. In this test the patient is seated at a standard distance and is asked to read letters or symbols of various sizes, which get smaller as you move down the chart. The results are the familiar ratio of 20/20, 20/40 etc. which is a comparison of your vision compared to the average person with good vision, which is typically 20/20. For example, a patient that has 20/40 vision, can only see at 20 feet what the normal person can see from a distance of 40 feet. This test is a preliminary test of how clearly you are seeing in each eye but it does not give you a prescription for corrective lenses.

Refraction

Those who don’t have 20/20 vision have what is referred to in most cases as a “Refractive Error.” The patient may have nearsightedness, farsightedness, astigmatism or other eye conditions that prevent the patient from seeing 20/20. A refraction will tell the doctor which prescription lenses will correct your eyesight to achieve 20/20 vision or whichever amount your vision is correctable to.

A refraction may include a couple of steps.

Retinoscopy

Retinoscopy is a test that allows the doctor to obtain an approximate prescription for eyeglasses. In this test the doctor uses a hand-held instrument called a retinoscope that shines a light into the patient’s eye. The doctor then analyzes the reflex of the light from the patient’s eye to determine the patient’s prescription for glasses.

An instrument called a phoropter is something most patients associate with an eye exam. This space age appearing instrument, positioned in front of the patient’s face during the eye exam, gives the doctor the ability to determine the patient’s focusing ability as well as their eye alignment. The phoropter also determines which, out of the hundreds and hundreds of potential eyeglass prescriptions, will help the patient see as clear as possible. Using the phoropter, the doctor will ask the patient which series of lenses makes their vision the clearest.

While retinoscopy is quite effective for children and nonverbal patients, there are now a number of computerized or automated instruments available today to help doctors accurately determine a patient’s eyeglass prescription.

Autorefractors and Aberrometers

Autorefractors and aberrometers are computerized machines that are able to measure your refractive error to determine your prescription for glasses or contact lenses. These instruments are usually used in addition to testing described earlier:

– An autorefractor is similar to retinoscopy, which electronically analyses the light reflex from the patient’s eye.

– An aberrometer measures distortions or aberrations in the cornea and lens of the eye that disrupt proper focus of light on the retina. Using wavefront technology, the instrument measures the rays of light as they pass through your eye to look for imperfections which may indicate a refractive error.

Eye Focusing and Eye Teaming Tests

During the comprehensive eye exam, your eye doctor will also want to test how your eyes function individually and together from a mechanical perspective. In order to see clearly and comfortably, your eyes need to work together as a team.

Eye Health

The final and most important aspect of a comprehensive eye exam is a check of your overall eye health. These tests (below) are done to identify any eye conditions or diseases, both inside the eye as well as the external parts of the eye, that could affect your vision and general health.

Slit Lamp Test

The slit lamp or biomicroscope is an instrument that allows the doctor to examine the internal and external parts of the eye in detail, such as the conjunctiva, iris, lens, cornea, retina and the optic nerve. The patient rests their forehead and chin on a headrest to stabilize the head, while the doctor looks into the eye with the slit lamp microscope, which is magnified with a high-intensity light. A slit lamp test enables the doctor to evaluate the eyes for signs of normal aging and eye pathology, such as conjunctivitis, cataracts, macular degeneration or retinal detachment. Early diagnosis and treatment of eye diseases are essential for preventing vision loss.

Tonometry

Tonometry is a test to detect glaucoma by measuring the pressure inside your eye or IOP (intraocular pressure). Glaucoma can cause vision loss and even blindness if the IOP in the eye is too high and damages the optic nerve.

The applanation tonometer, typically attached to a slit lamp, is one of the most common instruments used to measure the pressure in the eye. Prior to doing this test the doctor will numb the patient’s eyes using an anesthetic, before gently applanating (putting pressure on) the patient’s cornea to measure the pressure in the eye.

Pupil Dilation

During your comprehensive eye exam, your doctor may decide to do a dilated eye exam. In this test, your doctor will instill dilating drops in each eye, which would enlarge your pupils to give the doctor a better view of certain parts of the back of the eye. Dilation is done at the discretion of the doctor, with some patients dilated every year and others at specified intervals; the frequency of dilation will vary for each patient.

Typically the drops take around 20 to 30 minutes to take effect and may last up to several hours following the exam; each patient is different. Since more light enters your eyes when your pupils are dilated, you will be more sensitive to bright light, especially sunlight. Although your doctor may provide disposable sunglasses, you may want to bring a pair of sunglasses to wear after the exam to make it more comfortable until the drops wear off.

A comprehensive eye exam is an important part of your overall general health maintenance and should be scheduled on a regular basis. The findings from your comprehensive eye exam can give your doctor important information about your overall health, particularly diabetes and high blood pressure.

As a child’s eyes develop, it is not uncommon for a number of problems to occur. Beyond blurred vision due to refractive error including nearsightedness (myopia) and farsightedness (hyperopia), children can develop a number of other visual and perceptual problems that are often not detected by a simple vision exam. Even a child with 20/20 vision, can have underlying vision problems!

Some of these issues are functional vision problems having to do with the actual eyes, how they move individually and as a pair, as well as their ability to focus. Functions such as eye teaming, tracking, focusing, and hand eye coordination, all affect a child’s success in school, sports or general functioning. Often children that have difficulty with these functions will suffer physical symptoms as well such as headaches, eye fatigue or short attention spans. With these critical visual skills lacking, tasks such as reading and writing can be extremely difficult and exhausting which can lead to frustration and behavioral problems.

Just like we are able to train our bodies to build strength, speed and agility, our vision skills can be strengthened. Vision therapy offers a doctor-supervised program to guide children to develop these skills.

What is Vision Therapy?

Vision Therapy is a program of progressive eye exercises individualized for each patient designed to retrain or help the patient develop or improve upon particular visual skills or to improve processing and interpretation of visual information. It is used to treat conditions like strabismus (crossed eyes) and amblyopia (lazy eye) as well as eye movement, focus and coordination problems.

Typically, the sessions take place in the optometrist’s office weekly or bi-weekly and utilize a variety of tools such as therapeutic lenses or prisms. Often the patient will be asked to practice certain exercises or activities at home as well in order to reinforce the skills that are being developed. Through repetition of these tasks, the ultimate goal is to strengthen the skills such as focusing, and improving eye movement and alignment, to the point where the eyes and vision are working efficiently and comfortably. The duration of the therapeutic program usually lasts about 6-9 months.

Vision therapy has been scientifically proven to improve functional vision skills and is approved by the major optometric bodies such as the American Optometric Association and the Canadian Association of Optometrists. It does not improve refractive error and should not be mistaken for some of the alternative self-conducted eye exercises out there that claim to improve your vision.

Vision therapy has also been shown to be effective in adults. If you think that vision therapy could be right for your child or yourself, it is worthwhile to have an assessment by a trained vision therapist to determine whether it could help resolve the vision problems that are present.

Most parents believe that if their child had an eye or vision problem they would know. However, this is far from the truth for a number of reasons. First of all, children often can’t express or don’t realize the difficulty they are having, and often vision problems will be overlooked by the associated behavioral issues that come as a result of frustration. Further, many eye or vision problems don’t show symptoms until they have progressed significantly which often makes the condition harder to treat.

Conditions such as amblyopia (lazy eye) or strabismus (crossed-eyes) can be corrected more effectively when they are diagnosed and treated early at a young age. Further, the sooner you diagnose and correct a vision problem, the sooner your child will be able to achieve his or her potential without struggling with these difficulties. This is why it is critical to have your child’s eyes examined by an eye doctor at regular intervals. Here are some FAQ’s and answers about Children’s Vision that every parent should know:

Q: At what ages should children have their eyes examined?

A: The official recommendations for the American and Canadian Optometric Associations are that infants should have their first eye exams at 6 months. Following that, children with no known vision issues should have another exam at 3 years and then prior to entering kindergarten. Children who do not require vision correction or therapy should have a vision checkup every year or two years and those who use vision correction should have an annual eye exam. Of course if your child is experiencing difficulty in school or after school activities that may be due to a vision problem schedule an eye exam immediately.

Q: My child passed a vision screening by the nurse at school. Does he still need an eye exam?

A: Yes. Many schools implement a basic vision screening test to assess whether the child sees clearly at a distance, however these tests are limited in scope. They do not assess functional vision such as the child’s ability to focus, track words on a page or the eyes’ ability to work in tandem. They also do not look at the health of the eye itself. These tests are essential to know the comprehensive picture of how healthy the eyes are and how well they are doing their job. In fact, studies shown that up to 43% of children with vision problems can pass a vision screening test! A comprehensive eye exam will assess all of these functions as well as color vision, depth perception, and eye coordination.

Q: My child was diagnosed with strabismus and amblyopia. Can this be treated and if so, what are the options?

A: Especially when diagnosed early, chances of a complete correction for strabismus and amblyopia are good when treated properly. The optimal age for this to occur is before 8-10 years old. Depending on the severity of the strabismus (crossed-eye), surgery may be required to straighten and properly align the crossed eyes. Amblyopia (lazy eye) can then be treated using eyeglasses, eye patching, or vision therapy to strengthen the weak eye and train the eyes to work together. A doctor that specializes in pediatric optometry can assess the condition and discuss treatment options on an individual basis.

Q: What is vision therapy?

A: Vision therapy is a doctor-supervised, individualized program of exercises to strengthen the functions of the eye. It is used to correct issues with eye alignment, focusing, coordination, tracking and more. Vision therapy often utilizes tools such as specialized lenses or prisms and involves exercises both during office visits and at home to reinforce the changes. The process usually takes about 6 months to see lasting improvement.

Q: My son’s nearsightedness keeps getting worse – he needs a new prescription every year. Is there a way to stop this?

A: There is research that shows that progressive myopia can be stopped or slowed during the childhood years. There are a number of therapies that are used for what is called “myopia control” including multifocal eyeglasses or contact lenses, orthokeratology (ortho-k) or atropine eye drops. Speak to a pediatric optometry specialist to learn more about the options and what might work best for your child.

Q: Every morning it is a fight to get my child to wear her glasses. What can I do?

A: It may take time for your child to adapt to the feel of the glasses and to be comfortable seeing with them. For little children, you can find glasses that come with integrated headbands that can help to hold the glasses in place. It helps to be consistent in putting them on to allow the child to adapt to the feel of the glasses.

Very often, especially for small children that can’t tell you what is bothering them, the reason for a child’s refusal to wear glasses is that something is not comfortable. It could be that the prescription is not right, that the glasses pinch or that are feeling heavy. It could be worthwhile to take the glasses back to the eye doctor to ensure that they are in fact a proper fit.

Q: At what age is it acceptable for a child to wear contact lenses?

A: Contact lenses can be a great convenience, especially for kids that are active or tend to break or lose their glasses. However, they are a medical device that must be treated with proper care and hygiene. If a child is not responsible enough to take care of them properly he could end up with a serious eye infection, a scratched cornea or worse. Most experts agree that the youngest age that contact lenses should be considered would be between 10-12 depending on the child’s maturity and cleanliness. Consult with your eye doctor about what would be best for your child.

Your baby’s visual system is not fully developed at birth and continues to develop gradually over the first days and months of life. In fact, from your baby’s perspective at birth, the world is black and white, blurry and rather flat. As the days and months go on, they begin to focus, move their eyes and start to see the world around them. While each child will grow and develop on his or her own schedule, knowing an infant’s vision milestones will help you ensure that your infant is on track to achieving good vision and eye health and start treatment early if there is a problem.

Birth – 3 months

Because newborn babies’ eyes and visual system are underdeveloped, they can not focus their eyes on close objects or perceive depth or color. Babies need to learn to move, focus and coordinate eye movements to team the eyes (have them move together as a team). The brain also needs to learn how to process the visual information from the eyes to understand and interact with the world. In fact, until about 3 months, the optimal distance a baby can focus on is about 8 – 10 inches from their face, about the distance their parents face will be during feeding.

Your baby will start to be able to perceive color within the first 2-3 weeks, however it will take a few months to learn how to focus and use the eyes, to track objects, differentiate between two objects and shift from one object to the other. During this time you may notice that the eyes appear crossed and do not work together or team. This is quite common at the early stages of development, however if one eye appears to be constantly turned in or out, seek a doctor’s evaluation.

At around three months, as hand-eye coordination begins to develop, a baby should be able to follow a moving target with their eyes and reach for objects.

4-6 Months

By 6 months, your baby will begin to move his eyes with more speed and accuracy, seeing at farther distances and focusing well. Color vision should be fully developed and the eyes should be able to work as a team and follow moving objects with relative ease. Hand-eye coordination and depth perception should be greatly improved as your baby will begin to understand the 3-dimensional world around them.

At six months, you should take your baby for his or her first comprehensive eye exam to ensure that the eyes are developing on track and there are no signs of congenital or infant eye disease.

7-12 Months

At this stage of development babies will be coordinating vision and body movements by crawling, grasping, standing and exploring the surrounding world. They should be able judge distances accurately, throw a ball toward a target and pick up a small object with their fingers. Delays in motor development can sometimes indicate a vision problem.

The First Eye Exam

While at 6 months, your baby will not be able to read an eye chart, eye doctors can perform an infant eye exam through non-verbal testing to assess visual acuity (for nearsightedness, farsightedness or astigmatism), eye teaming abilities and eye alignment. The eye doctor will also be able to see inside the eye for any signs of disease or problems that could affect eye or vision health.

InfantSEE®

InfantSEE® is a public health program in which participating optometrists provide a free comprehensive infant eye exam to babies between 6 and 12 months of age. The program was initiated to provide accessible eye and vision care for infants to ensure they have the best chances for normal development and quality of life.

If your child has any unusual symptoms such as excessive tearing, constant eye misalignment, red or crusty eyes or extreme light sensitivity consult an eye doctor as soon as possible.

Many children who wear glasses want to switch to contact lenses, especially older children who are concerned with their appearance. So, how do you know if and when contact lenses might be an option for your child?

Contact lenses may not only improve a child’s confidence in their appearance but they can also be very convenient for active children who play sports or those who tend to lose or break their glasses.

Yet before you jump to schedule an appointment with the optometrist, it’s important to know that while contact lenses are a great solution for many, they are still medical devices that require care and responsibility. Carelessness with contact lenses can lead to infections, irritation, scratched corneas, pain, and sometimes even vision loss. So if you want to know if contact lenses are a good choice for your child, read below and think about whether your child is mature and responsible enough to take proper care of his or her eyes.

At What Age Can a Child Start Wearing Contact Lenses?

The recommended age for kids to start considering contact lenses varies however it is generally accepted that sometime between 11 and 14 is ideal. Some doctors will recommend them even for children as young as 8 years old who have shown that they are responsible enough to use them. Contact lens use requires good hygiene and cleanliness so if your child shows those traits, she may be ready. Additionally, if he is highly motivated to wear contacts and if he has the support of his parents, this will help in ensuring that the daily regimen is a success.

What is the Process of Getting Fitted for Contacts?

The first step is to schedule an appointment for a contact lens exam with your optometrist. The eye doctor will perform a vision exam and go over the different options for contact lenses, depending on the prescription, the health of the eye and lifestyle and personal preferences. Contact lenses are designed with a number of options including the lens materials used (soft or rigid gas permeable), the replacement schedule (if disposable, how often you replace the pair – daily, weekly, biweekly or monthly) and the wear schedule (daily or extended overnight wear). Often doctors will recommend daily lenses for children because they are thrown away after each use so there is less care involved, less buildup and less risk for infection.

Then the doctor will give a training on inserting and removing the lenses as well as instructions for proper care. Your child will probably be given a schedule for wearing the lenses for the first week or so in order to allow their eyes to adapt. During this time you may have to be in touch with your eye doctor to assess the comfort and fit of the lenses and you may have to try out a couple of options in order to find the best fit.

Purchasing Contact Lenses

As a medical device, contact lenses require a prescription and should only be purchased from a licensed distributor such as an eye doctor. Unauthorized or unmonitored contact lenses can cause severe damage to your eyes that could result in blindness. This is true also for cosmetic lenses such as colored lenses or costume lenses. Any time you are putting a lens in your eye, you must have a proper prescription.

Following are some basic contact lens safety tips. If your child is responsible enough to follow these guidelines, he or she may be ready for contact lens use:

1. Always follow the wearing schedule prescribed by your doctor.
2. Always wash your hands with soap before applying or removing contact lenses.
3. Never use any substance other than contact lens rinse or solution to clean contacts (even tap water is a no-no).
4. Never reuse contact lens solution
5. Follow the eye doctor’s advice about Don’t swimming or showering in your lenses
6. Always remove your lenses if they are bothering you or causing irritation.
7. Never sleep in your lenses unless they are extended wear.
8. Never use any contact lenses that were not acquired with a prescription at an authorized source. Never purchase cosmetic lenses without a prescription!

Contact lens use is also an ongoing process. As a child grows, the lens fit may change as well, so it is important to have annual contact lens assessments. Plus, new technology is always being developed to improve comfort and quality of contact lenses.

Contact lenses are a wonderful invention but they must be used with proper care. Before you let your child take the plunge into contact lens use, make sure you review the dangers and safety guidelines.

Childhood myopia or nearsightedness is a common condition that causes blurred distance vision and can usually be easily corrected with either glasses or contact lenses. Unfortunately, simply getting a pair of glasses doesn’t always solve the problem, because often myopia is progressive which means that every year the vision gets worse. This usually continues until sometime around the child’s 20th birthday when his eyes stop growing and eyesight levels off.

It can be worrisome and quite disconcerting for both the parent and the child when each visit to the eye doctor results in a higher prescription. There could be a number of factors involved in progressive myopia, involving hereditary factors as well as possible environmental or behavioral factor such as frequent close-up tasks such as reading or using an electronic device. In fact, studies show that children that spend more time outdoors playing have a lower incidence of myopia. Much research is currently being done into treatments for slowing or stopping myopia progression in children. Here are some of the treatment options currently being offered:

Orthokeratology (Ortho-k)

Ortho-k is a process that uses specially designed rigid gas permeable contact lenses worn at night to gently reshape the cornea, eventually allowing clear vision during the day. The lenses are worn every night or every couple of nights depending on the results of the individual. Ideal for mild to moderate myopia, ortho-k usually takes a few weeks to show results, during which time the patient may need to temporarily continue wearing glasses or contact lenses.

Studies show that the use of ortho-k can permanently reduce the progressive lengthening of the cornea which is responsible for nearsightedness and can therefore slow or stop the childhood progression of the condition. Therefore, in addition to being used for myopia correction, it is now also being offered as a therapeutic treatment to halt myopia progression in children.

Multifocal Eyeglasses or Contact Lenses

Bifocal or multifocal soft contact lenses or glasses have been shown in some studies to slow myopia progression. This therapy is based on the idea that the eye is strained from accommodating to see close up and that by providing multiple focusing powers, this allows the eye to relax when doing near work, which reduces the progression of the refractive error. This treatment has been shown to delay or slow the advancement of myopia in some children.

Atropine Drops

Treatment with atropine drops is another therapy that is used to relax the eye from “focusing fatigue” which may be a culprit in myopia progression. Research is still being done but some studies show that daily use of low doses of atropine drops do slow the progression of myopia. Atropine drops dilate the pupil which temporarily prevents the eye from being able to focus, thereby allowing this mechanism to relax. Research is still being done to determine dosages, but the results are promising.

If your child has progressive myopia, seek out a pediatric optometrist who is knowledgeable about the options available. Finding the right treatment could give your child the gift of better eyesight for life.

In recent years there have been tremendous advances in the field of vision correcting eye surgery which is also known as refractive or laser surgery. Corrective eye surgery offers patients clear vision without the use of glasses and contact lenses. There are a number of types of refractive surgeries that are able to correct different vision problems, so if you are considering surgery here are some of the options you should know about.

LASIK

LASIK (laser-assisted in situ keratomileusis) surgery is perhaps the most well-known refractive surgery today. LASIK can help patients with myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. During the procedure, the doctor makes a flap in the outer layer of the corner to reach the underlying tissue and then uses a laser to reshape the tissue which allows the cornea to then focus light properly. The procedure is usually painless and vision is usually clear within a few hours.

Recent advances in the field have developed subcategories of LASIK surgery such as Bladeless LASIK, which uses a laser rather than a mechanical tool to make the initial flap or Wavefront (custom) LASIK which uses computer mapping to guide the reshaping of the cornea and is able to create a much more precise visual correction for very subtle optical imperfections. There is also a procedure called Epi-LASIK in which following the procedure, the doctor applies a soft contact lens to protect the surgical area, holding the flap in place while it heals.

PRK

PRK (photorefractive keratectomy) also uses a laser to correct mild to moderate myopia, hyperopia and astigmatism. PRK was a precursor to LASIK which eliminated many of the complications of prior surgeries such as glare, seeing halos around lights, blurred vision and regression of vision. Unlike LASIK, the procedure only reshapes the surface of the cornea and not the underlying tissue. Consequently, there is often some discomfort for a couple of weeks until the outer layer of the cornea heals. Additionally, the patient may experience blurred vision during this period of healing. PRK does offer an advantage over LASIK in that there is less risk of certain complications. Wavefront technology is also available for PRK surgeries.

Due to the increased comfort of LASIK there was a period that PRK saw a decline. Recent studies show however that LASIK and PRK have similar long-term success for improved visual acuity and with the assistance of newly developed effective pain medications, PRK has become more popular again as an option.

LASEK

In LASEK or laser-assisted sub-epithelial keratomileusis, the doctor creates a flap smaller but similar but to LASIK, and then uses an alcohol solution to loosen the tissue around the cornea which is pushed aside, and then a laser is used to reshape the cornea itself. In an Epi-LASEK procedure, the doctor may apply a soft contact lens to hold the flap in place to assist in reattaching to the cornea as the eye heals. Patients that undergo LASEK generally experience less discomfort and quicker vision recovery than PRK patients. LASEK may be preferred over LASIK as a safer option for patients with a thin cornea.

Cataract Surgery

Cataract Surgery is a very common refractive surgery that removes the clouded natural lens of the eye and replaces it with an artificial lens called an IOL (intraocular lens). Many patients these days will receive a lens that also corrects any refractive error they have such as nearsightedness, farsightedness or presbyopia.

RLE

RLE or refractive lens exchange is a non-laser procedure the replaces the natural lens of the eye. This is the same as the surgery that is used to treat cataracts, ,yet for non-cataract patients, RLE is used to correct severe nearsightedness or farsightedness. The procedure involves the doctor making a small cut in the cornea, removing the natural lens and replacing it with usually a silicon or plastic lens. It is particularly useful for patients with minor corneal problems such as thin corneas or dry eyes.

RLE is more risky than the other procedures mentioned and can affect the patient’s ability to focus on close objects, possibly requiring reading glasses following the procedure. However, in cases of severe vision correction it is often the preferred method.

PRELEX

PRELEX or presbyopic lens exchange is for patients with presbyopia, the age-related condition in which you lose the flexibility of your lens and can no longer focus on close objects. Patients that prefer not to wear reading glasses or multifocals, can opt for a procedure in which the doctor removes the natural lens of your eye and replaces it with a multifocal artificial lens. This procedure is often done in conjunction with cataract surgery.

Phakic Intraocular Lens Implants

Phakic IOLs are implants that are used for individuals with very high nearsightedness who do not qualify for LASIK or PRK. The implant is attached to your iris or inserted behind your pupil, while the natural lens remains intact. Because this is a procedure that involves the inner eye, it is more risky than LASIK or PRK and is therefore also typically more expensive.

Conductive Keratoplasty (CK)

CK uses a hand-held radio wave device to shrink tissue on the cornea to reshape it. The procedure is typically used to treat mild farsightedness and presbyopia, particularly for patients who have already undergone LASIK.

Any surgical procedure has risks and may have some side effects or complications that you should research before you decide to go ahead with the surgery. Nevertheless, as technology advances these complications are being significantly reduced making refractive surgery a great option for vision correction in many patients.
