myopia control



Dr. Galan feels extremely passionate about the benefits of Ortho K for the following reasons:

  • Ortho K is the most effective method of reducing the progression of myopia in children.
  • Ortho K leaves the child glasses and contact lens free during the day, which improves visual performance in school and sports and is a huge boost in their self esteem.
  • Because your child is glasses and contact lens free during the day they are at less of a risk of sports related eye injuries which effect 40,000 children per year.

What is OrthoK

Orthokeratology, commonly called ortho-k, is a method used to correct myopia (nearsightedness) by wearing rigid gas permeable contact lenses overnight, so that no vision correction is needed during daytime hours.

Gas permeable (GP) lenses specialized for ortho-k are inserted at bedtime and worn as you sleep. Throughout the night, the lenses reshape your cornea gently so that your vision becomes clear on the following morning. The correction is temporary, and ideally no eyeglasses or contact lenses will be needed on the next day or two. In order to maintain sharp visual acuity on a daily basis, you need to wear the ortho-k reshaping lenses every night.

Candidates for Ortho-K

Ortho-k is very suitable for nearsighted people who are not appropriate candidates for vision correction surgery, such as children. Individuals of all ages with healthy eyes can try ortho-k, namely because it can be discontinued at any point without permanent effects to the eyes.

People who require vision correction and engage regularly in sports or work in extremely dusty, dirty environments will also appreciate the convenience of ortho-k.

Vision Results from Ortho-k

Success rates for ortho-k are generally higher for more mild vision prescriptions. The ideal goal is to provide 20/20 vision without any need for eyeglasses or contacts during the day.

According to FDA trials conducted on both CRT and VST lenses, more than 65% of ortho-k patients were provided with 20/20 visual acuity. A whopping number of more than 90% of ortho-k patients achieved 20/40 vision or better (this is the legal requirement for driving without vision correction in most states). Consult with your eye doctor to find out if your vision prescription is within range for successful ortho-k treatment.

How Does Ortho-k Feel?

Although some people have trouble wearing regular gas permeable contact lenses during the day, ortho-k GP lenses are worn while sleeping – so discomfort and awareness of the lenses in your eyes is generally not an issue.

Is Ortho-k expensive?

Professional fitting for ortho-k requires a series of visits to your eye doctor. A number of pairs of contact lenses are also generally needed. GP lenses that are special for ortho-k are more costly than standard contacts. In sum, the fees for ortho-k add up to a higher total than regular contact lenses.

LASIK after Ortho-k

Refractive surgeries, such as LASIK, are possible after treatment with ortho-k lenses. Yet because ortho-k works to reshape your cornea, you are required to stop wearing the lenses for approximately several months before undergoing LASIK. This allows your eyes to return to their original shape.

It’s important to inform your LASIK surgeon if you’ve been wearing ortho-k lenses, and you will be advised as to how long of a wait is necessary before having the laser procedure.

Vision Correction

Did you know that nearly 9 and a half million American adults have myopia? That’s nearly 4% of all adults in the entire country! 30% of Canadians have the condition, as well, making it one of the most common vision problems globally—and these numbers are on the rise.

At Ortho-K & Myopia Management Center At Diamond Vision, Dr. Shane Galan and the staff help patients with their vision correction needs. If you or a loved one have any vision difficulties, we can help.

All You Need To Know About Vision Correction

Vision Correction is used to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism (when light enters the eye incorrectly), or presbyopia (farsightedness due to aging).

What Is A Refractive Error?

The ability to see images or objects with clear, sharp vision results from light entering the eye. Light rays bend or refract when they hit the retina, sending nerve signals to the optic nerve, which then sends these signals to the brain. The brain processes them into images, allowing you to understand what you see. When these light rays bend incorrectly, it results in a refractive error and typically causes blurry or cloudy vision.

Your eye doctor will often prescribe eyeglasses or contact lenses to correct the vision impairment. Glasses and contacts enhance your vision by shifting the way that images enter your eyes. They refract light properly, so that your brain processes images correctly, resulting in clear vision. However, corrective lenses do not cure vision problems; they simply enhance your existing vision.

What Is Considered “Vision Correction”?

Since the primary cause of vision problems is caused by light bending incorrectly as it enters the eye, virtually any method of treatment that changes this can be categorized as a form of vision correction.

Eyeglasses and contact lenses – the most common types of corrective measures – are almost always recommended as the first course of treatment for vision problems. While they are considered a very basic method of vision correction, they are unable to control the refractive error from progressing. Patients whose vision worsens over time need new glasses or contacts. In these cases, longer-term solutions are needed.

Deciding upon the right course of treatment for refractive errors can depend on several factors such as age, your lifestyle and daily activities, eye health, and overall physical health. Dr. Shane Galan will conduct a thorough eye exam and discuss your and your family’s medical history to get a complete picture of your vision needs.

The Benefits Of Vision Correction Without Surgery

When eye surgery is performed and the corneal tissue – or the cornea itself – is repaired or reshaped, it is generally permanent. Surgical procedures are matters of a serious nature and are often the last resort, when all other vision correction options have been exhausted. That’s why most doctors recommend non-surgical treatment methods first.

teen smiling 6 640Some of the benefits of non-surgical vision correction include:

  • Less invasive: surgery is an invasive procedure which involves corneal incisions, whereas non-surgical corrective treatments are less intense with lower risks
  • Not permanent, so it’s easier to try different treatment methods to find which ones work for your needs
  • LASIK has ZERO guarantees for how many years you’ll enjoy 20/20 vision. Whether you have 1 year or 10 years is completely up to your eyes. Orthokeratology, however, provides guaranteed 20/20 vision or better as long as you wear the lenses.
  • Orthokeratology can correct both near and far vision. LASIK is only for nearsightedness.
  • Some patients may not be good candidates for eye surgery due to age, a thin cornea, or the presence of other viruses or eye conditions. For example, a patient with chronic dry eyes could be ineligible for LASIK, since this surgery can exacerbate symptoms of Dry Eye.

Vision Correction is Safe For Kids As Young As 6 And For Adults Over 60!

Non-surgical vision correction is safe for children as young as 6 and adults over the age of 60.

Some vision correction surgeries cannot be performed on patients under 21 years old. Kids’ eyes are still developing and their vision is unstable, so most doctors prefer to wait until their young patients’ eyes stabilize before considering surgical vision correction.

As we age, our vision changes. Typically beginning in middle-age, the lens of the eye begins to lose some elasticity causing presbyopia, a form of farsightedness. Presbyopia can be treated with corrective lenses, including multifocal lenses. Multifocal lenses have various degrees of lens power, which helps the patient experience clear vision in any direction – up, down, and to the sides.

If you or a family member needs vision correction and you’re looking for a safe, risk-free treatment, contact Ortho-K & Myopia Management Center At Diamond Vision to schedule a consultation.

Vision Correction Is Good For Athletes, Travelers & Business Leaders


Competitive sports is more than just a game. The ability to see clearly from both near and far distances is critical in sports. Athletes with nearsightedness, farsightedness, or astigmatism can’t play well if they can’t see well. The right vision correction can provide the visual clarity that serious athletes need to play and win!

People Who Travel

Whether you travel for business or pleasure, air travel can lead to dry eyes. This is due to the air pressure and dry environment that’s inside of the airplane cabin. Some people find that administering artificial tears provides the relief they need. If you generally wear contact lenses, swap them for glasses during the flight to avoid painful dry eyes. This is especially important for long, international flights.

People Who Need That Edge In Business

In the digital age, we enjoy constant connectivity to our smartphones, computers, and tablets. For business people with vision problems, who need to remain connected with a high level of visual clarity, getting the right vision correction treatment is not only beneficial for their visual health, but for their jobs.

So if you need to be at the top of your game in business, talk to Dr. Shane Galanabout your vision needs. We’ll focus on improving your vision, so you can focus on your business.

If you suffer from vision problems, contact Ortho-K & Myopia Management Center At Diamond Vision. Our caring staff will provide you with the best vision correction treatment that’s right for you.

Myopia Management

With myopia management, your child may be able to avoid the use of thick corrective glasses, which may lead to serious eye problems later in life.

If you are the parent to a child suffering from myopia, you must be wondering if there is a way you can cure it or at least, slow the progression of the nearsightedness to prevent the changing prescription and the risks of vision loss that is correlated with medium and high myopia (nearsightedness).

Recent research has started providing answers. Eye care specialists have found that it is possible to control the progression of myopia in children and teenagers.

Is There A Cure For Myopia?

As of now, we do not have an outright cure for the condition. However, there are ways in which the progression of myopia can be controlled.

Myopia management treatments may deal with induction of structural changes in the eye and altering its focus to relieve focusing fatigue, which is one of the main causes of the progression of myopia.

Popular Methods Of Myopia Management

Some of the treatment methods that work well for most cases of myopia are:

Use Of Multifocal Soft Lenses

Multifocal lenses, which have different powers in different areas have been found to control presbyopia and myopia. These have been seen to effectively reduce myopia progression by about 50 percent, which is similar to the results of ortho-k lenses. These soft contact lenses are used like regular contacts, leaving your child with great vision while reducing the risks of high and medium myopia. 

    Pros -

  • One of the simplest treatments
  • Effective
  • Kids love not having to wear glasses. 

    Cons -

  • Children need to handle them well
  • They need to be used the whole day
Use Of Multifocal Eyeglasses

Though this control progression rates better than single vision lenses, they are not as effective as multifocal contacts, or Ortho K (also called GVSS or CRT). Because of the low rates of slowing down myopia progression, most experts do not consider this option effective enough to fully reduce the risks of vision loss from high myopia.  

    Pros -

  • Easy to use
  • More effective than single vision lenses

    Cons -

  • Not as effective as Ortho K contact lenses and soft multifocal myopia management contact lenses.
  • Not highly regarded by eye care professionals.  
  • Glasses increase the likelihood of eye injuries in children. 
  • Social stigma and not for sports. 

This treatment involves the use of gas permeable lenses during bed time instead of using vision correction methods for the entire day. The average reduction in myopia progression using this method is around 45 percent. Learn more about Orthokeratology & Myopia Management.

Pros -

  • Effective
  • A well-fitting lens provides a continuous peripheral myopic defocus to the retina
  • The optics are present at all times

Cons -

  • More invasive than spectacle lenses
  • A poor fit of the lens may lead to changes in corneal shape and corneal damage post-treatment

Myopia Epidemic

Losing Sight of Our Children?

Female Child Looking Upward 1280×480With children spending less time outdoors & more time looking at computer screens, it is estimated that by 2050 half the world's population with be nearsighted.

Myopia is people who can't see clearly if somebody is walking towards them, they might not recognize their face because it's blurry.

It's reached epidemic proportions in Asia, but it's truly gone up significantly throughout the world, that's a serious potential public health problem.

A young baby, for example, is what we call hyperopic, which means the eyeballs are a little bit too small for the power of the optics, and it has to grow in this coordinated way in order to get things in focus.

Normally light comes in and is focused on these cells at the back of the eye. When the eye is too long the light stops short of those cells, so all you can do to fill the focal positioning gap is by putting spectacles or contact lenses on the eye. That doesn't change the fact that the eye is basically too long and is actually growing too much.

What happens when you turn and focus the lens of a camera is you're actually making the lens further from or closer to the material that absorbs light.

Child Female Wearing SunglassesYoung children as they develop are not going to experience prolonged constant blur all the time, but when they are looking at something up close, things in the distance are blurred, or they are looking at something far away, and things up close are blurred. As you move your eyes around from one place to another, you do all kinds of different things with your eyes and experience all kinds of different environments so the blur will vary from one moment to another.

There is a process by which the eyes will grow into focus over time, and most children born farsighted, over the first decade of their life that farsightedness diminishes, if their farsightedness diminishes too fast that's a predictor of the whether they're going to become myopic. The critical point is really about the beginning of school age when the risk is very high that the eyes are getting too long because the lens can no longer compensate for any further growth.

Children are spending more time indoors studying or watching TV may be at greater risk of developing myopia. If you're reading a screen or a book the optics are the same apart from one big difference; what you're reading is emitting light and that certainly could make a difference. The higher the myopia is the more difficult it is to prevent further progression.

pink eye girl rubbing1280x853If it were not for glasses, people with myopia would be profoundly disabled. The eye is responding to what it sees so to get that we have to understand what is actually in the image the eye is capturing that tells it whether to grow or not to grow.

The indoor environment is very hard the get everything focused at the same time. The outdoor environment pretty much everything is in focus at the same time.

In our visual system we have an on and off system between the eye cells that fire when the light gets brighter and the other cells fire when it gets darker. This is a typical arrangement all along our visual pathways, so it will be nice to generate stimuli that stimulate mainly the on the cell because they are releasing dopamine, and dopamine is known to inhibit eye growth. Therefore, in this case, we have the movie in the middle so they can at least watch a movie but they are still stimulated with on and off stimuli in the periphery. The focus is not the point here, what you need is stimulation of the on and off cells in the retina, because the on cells stimulate dopamine, and the off cells do not. The most important thing is for people to know how bad it can get.

Methods Of Myopia Management

Ortho K

Ortho K contact lenses are custom made contacts that are worn while you sleep and gently shape the eye leaving you with great vision without the aid of glasses or contacts. Ortho K is also known as GVSS or Orthokeratology and is considered the best choice for children with Myopia to reduce their risk of eye diseases as they age. Kids are particularly fond of Ortho K because they are able to be glasses/contacts free during the day which improves self esteem, vision, and reduces the risk of eye injuries.

Soft Multifocal Contacts

Soft multifocal contact lenses are becoming more and more sought after as a method of myopia management. Studies show that multi focal contacts are very effective at reducing the progression of myopia (commonly known as nearsighted or shortsighted). Contact lenses provide a great solution for ensuring your child is safe when playing sports, and studies show that children who wear contact lenses have a higher self esteem, and are accepted by their peers more than those that wear glasses. Because contacts are on the eye they provide better periphery vision than glasses.

Control Myopia Progression With Soft Contacts!

Myopia Management with soft multifocal contact lenses has been shown to slow the progression of children’s nearsightedness.

80% of learning is visual. Give your child the best chances for success!

What Are Multi Focal Contacts?

Depending on the design of the contact lens, multi focal contacts provide a range of powers in the same lens, using one of two methods.

The alternating vision method means your eye focuses on one of the options in the lens depending on the task. Whereas the simultaneous vision method means your eye see through all the power options and automatically chooses the correct focus depending on the task.

Multifocal contacts are available in different forms, soft, GP, and silicon hydrogel. Talk to your optometrist about the different options and which one is right for your child’s eyes. It is important to mention that there have been major advancements in contact lens design over the past years, which means that the comfort, quality of vision, and ease of use are all vastly superior to the contacts used ten years ago. For information about orthok read Understanding Orthokeratology.

The most common form of multi focal contacts uses concentric circles with different powers depending on the task. For example close work like reading, verses far focus activities like watching sports or going to the park.

Soft contact lenses are safe for children. To see if soft contacts are right for your child, you will need to schedule a myopia management evaluation with our optometrist located in Rockville Centre, Long Island.

Soft Contacts For Myopia Management

There is significant research that highlights the efficacy of soft multifocal lenses to reduce myopia progression in children. Because of the long term health implications associated with medium and high myopia, our optometrist strongly urges all parents with myopic children to discuss myopia management options.

Contacts & Your Child

Research has shown that children overwhelmingly prefer contact lenses to glasses, and children as young as 8 years old found contact lenses easy to care for by themselves. Children should be old enough to follow instructions for caring for their lenses.

OrthoK For Adults: A Lasik Alternative

Are You Looking For A Lasik Alternative?
Diamond Vision Provides Ortho K For Adults In Nassau County

Are you interested in being glasses and contact lens free, but are nervous about lasik eye surgery? Perhaps you have heard that you may not be a candidate or that the surgery does not leave every patient glasses free? With Ortho K contacts worn while you sleep, leaving you glasses and contact lens free for the next 1-3 days.



Ortho K contacts are specially designed contact lenses built to match the detailed map of your eye. And just like a retainer or orthodontics which gently shape your teeth, Ortho K contacts gently shape your eyes while you sleep. For most patients this leaves them with 20/20 vision from when they wake up until they go to sleep, without using glasses or contact lenses. In many cases the Ortho K contacts will achieve their desired level of correction within the first two weeks of wearing them. Many of our patients say they only need to wear the contacts once every 2 or 3 days to achieve perfect vision during the day.

Read more about Ortho-K Basics


There are many benefits associated with Ortho K contacts such as:

  • They are around half the price of Lasik.
  • Ortho K is not permanent.
  • 74% of adults using Ortho K achieved 2020 vision
  • Lasik surgery has many associated risks such as:
    • Dry eyes
    • Vision becoming worse or partially corrected
    • Severe eye conditions such as double vision, problems with night vision and contrast, and glare/halos.


While most adults are eligible for Orthokeratology, there are certain people who are more suitable. As a general rule, adult candidates for Ortho K should have nearsightedness under 6.0 or Astigmatism under 1.5.

  • Working in emergency services where glasses and contacts can get in the way.
  • Work environments that are dusty such as construction, which can be difficult for contact lens wearers.
  • People who need their best vision, such as professional athletes and military.
  • Patients who are not candidates for Lasik eye surgery.



Our eye doctor and eye care team focus on providing cutting edge eye care and eye wear to residents of Nassau County Long Island. Our eye doctor places a strong emphasis on being up to date on the latest methods of eye care, and takes his time with every patient to explain every option in detail.


Our practice values cutting edge eye care that provides real benefit to our patients. For our patients who come from across Nassau County, Ortho K has provided both young and old patients a leading option in vision correction. Ortho K is safe, effective, easy, and cost effective when compared to eye surgery.


A lot of eye care practices pay lip service to the idea of putting your patients first. Our practice is 100% committed to giving our patients the very best eye care experience whether they are visiting for a basic eye exam or Ortho K. Our patients love what we are doing and that is why we are so fortunate to have over 100 glowing reviews on Google.

Ortho-K Basics

asian girl 20s happy eyewear close upOrthokeratology, also known as ortho-k, is a special non-surgical vision correction procedure involving special gas permeable contact lenses that are worn each night while you sleep, to gently reshape your cornea and correct your vision. The cornea is the front part of your eye that helps shape light as it enters. If the cornea is not shaped correctly, images become blurry and hard to discern.

What is Ortho-K? Orthokeratology gently reshapes your cornea, giving it the proper shape to bend light to give you the best sight possible. The fact that this procedure takes place while you sleep means that each morning, when you wake up, all you need to do is take out your contact lenses and you are able to enjoy improved eyesight up to 20/20 all day.

Many people with mild to moderate nearsightedness, with or without astigmatism may benefit from the use of ortho-k lenses. Since the effects of ortho-k lenses are reinforced only if worn every night, if wear is discontinued, your eyes return to their original shape. Risk for ortho-k is, therefore, quite minimal and ortho-k patients can discontinue at any time without adverse effects. Use of Ortho-k also does not rule out LASIK in the future. Although Ortho-k lenses are primarily prescribed to correct nearsightedness, they also may be used to correct astigmatism, farsightedness and, in some cases even presbyopia.

If you would like to be glasses and contacts free but are not an ideal candidate for refractive surgery either because of age or other eye conditions like dry eyes, you may still benefit from ortho-k.

teen girlDuring your specialized ortho-k fitting, your eye doctor will ensure you are a good candidate for ortho-k lenses and make sure that the lenses are properly fitted for comfort and safety. The eye doctor will begin by obtaining measurements of your “corneal topography.” This procedure is painless and takes only about a minute. This gives the doctor a detailed picture of the unique topography of your eye. Your doctor will then either fit you from an in-office inventory of ortho-k lenses, or may order a custom pair for fitting at a later appointment. The first pair or two of lenses are usually temporary, in order to start the process of re-shaping your cornea. By the third pair, most people can expect to reach their fullest level of vision correction.

The amount of time it takes to begin experiencing a change of vision with ortho-k varies from person to person. Some people may have great vision after a day or two of using ortho-k lenses overnight, whereas those that require a stronger prescription may take up to a few weeks before attaining the full benefit.

It is important to note that Ortho-k lenses are highly specialized and only specially certified optometrists are able to provide fittings for these lenses.

What is Ortho-K ?

How does Ortho-K work and Who is it for?

Orthokeratology is an innovative way of slowing down a child’s nearsightedness.  Basically, the child or adult sleeps in a rigid contact lens, and in the morning the patient will remove the contact lens, and see clearly for the rest of the day.  This procedure is repeated every night.

Orthokeratology contact lenses reshapes the cornea while the patient sleeps.  The contact lenses apply a gentle amount of pressure that reshapes the cornea surface.  As a result of the cornea changing shape, the patient’s prescription will be corrected and eyeglasses or contact lenses will not be needed for that day.  Ortho-K for all ages, Rockville Centre, NY

The process of orthokeratology is not 100% understood.  However, it seems that the orthokeratology contact lenses prevent the cornea from changing shape and as a result, will slow down the progression of myopia (nearsightedness).

What makes orthokeratology exciting is the fact that a child can go to school eyeglass or contact lens free.  In addition, it gives the doctor and parent a way of slowing down the amount of nearsightedness and the child’s vision can hopefully stabilize at an earlier age.

The patient’s vision upon removal of the contact lenses should be the equivalent as their vision is with their conventional contact lens.  More importantly, over the next several years, we usually notice that the prescription has decreased slightly or has not changed at all.  This statement cannot be said with eyeglasses or conventional soft contact lenses which usually increase 25% a year.

Patients are usually delighted to know that they do not have to rely on eyeglasses or regular soft contact lenses in order to see clearly.  They like the ability to see without anything in their eyes during the day. The orthokeratology patient is no longer concerned that their soft contact lenses are bothering them, or that their eyeglasses are cumbersome.  The orthokeratology patient (and or the parent) is thrilled after their yearly exams when I state that the prescription has not changed and their vision is stable.

Orthokeratology is not for everyone especially if you have a very strong prescription, or have corneal disease (example keratoconus)   Good candidates are children with myopia (nearsighted/shortsighted) , previous contact lens drop outs due to poor comfort with conventional soft contact lenses, those who play sports or other hobbies that require optimal vision but can’t wear contact lenses or eyeglasses, and emergency personnel that require great vision without glasses or contacts. Also, those individuals who want to keep their prescription as low as possible in order to have LASIK in the future, are ideal candidates.

How Can Orthokeratology Help With Myopia Management?

Is your child wearing glasses or contact lenses for myopia? Is their optical prescription continually worsening every 12 to 18 months? If so, it may be time for a myopia management program featuring ortho-k contact lenses.

Orthokeratology, or “ortho-k,” is an overnight process of vision correction that leaves your child free of daytime eyewear. Along with the convenience of not having to wear glasses or contacts during the day, ortho-k has been shown to slow down or even stop the progression of a child’s myopia. An additional — yet compelling — benefit is the reduced risk of developing serious ocular conditions and diseases later in life, such as macular degeneration and retinal detachment.

If your child has myopia, speak with Dr. Shane Galan regarding the benefits of wearing ortho-k lenses for myopia management.


How Ortho-k Works

Orthokeratology goes by a few names:

  • Ortho-k
  • CRT (Corneal Reshaping Therapy)
  • Gentle Vision Shaping System (GVT or GVST)
  • Vision Shaping Treatment (VST)
  • Corneal Molding

Regardless of the name used, ortho-k is an established non-surgical method of vision correction that has been safely used for over 20 years. Dr. Shane Galan will carefully measure the child’s eye and order custom-fitted and specially-designed rigid gas permeable (RGP) contact lenses.

The ortho-k lenses are to be worn overnight, during which time they gently correct the shape of the cornea. The lenses are then removed in the morning, leaving your child with crisp and clear vision all day long. As mentioned above, ortho-k not only corrects vision but can also slow —or even halt — the progression of myopia in children.

Currently, there are two brands of orthokeratology approved by the FDA: Corneal Refractive Therapy (CRT) from Paragon Vision Sciences and Vision Shaping Treatment (VST) from Bausch & Lomb. Dr. Galan will advise Long Island patients as to which system is best for their lifestyle.

Who Can Benefit From Orthokeratology?

Orthokeratology is frequently a good option for nearsighted individuals who are too young for LASIK surgery or for some other reason are not good candidates for vision correction surgery. Because it can be discontinued at any time without permanent change to the eye, people of any age can try the procedure, as long as their eyes are healthy.

Ortho-k is particularly appealing for people who participate in sports, or who work in dusty, dirty environments that can make contact lens wear difficult.

Both children and adults can benefit from the vision correction provided by ortho-k, though ortho-k may be the ideal solution for myopia management in children. While it is too late to slow the progression of myopia in adulthood, myopic children who wear ortho-k lenses can further benefit by lowering any risks associated with ocular diseases later in life.


What Is The Fitting Process For Ortho-k Lenses?

At Ortho-K & Myopia Management Center At Diamond Vision, our patients undergo a full ortho-k assessment before being fitted for these lenses. Dr. Shane Galan will evaluate the health of your child’s eye and determine the exact corrective prescription. To measure the precise curvature of the child’s cornea, Dr. Shane Galan will use a topographer, ensuring these customized lenses are a perfect fit.

After the initial fitting, patients will be provided with detailed instructions and in-clinic training on how to insert, remove, and care for their o
