Advanced Orthokeratology


All Day Freedom From Eyeglasses and Contact Lenses

Safely Stop or Slowdown Nearsightedness in Children

Available for Both Children and Adults

A Non-Surgical Alternative to LASIK

Now there is an alternative to glasses and daytime contact lenses without surgery

Introducing AOK Advanced orthokeratology, an advanced procedure that gently reshape the cornea while you sleep.

There are several names for orthokeratology but the overall concept is the same. Some of the names are Wave Ortho-k, corneal refractive therapy (CRT® ), corneal refractive treatment, vision shaping treatment® (VST), and overnight vision correction (OVC). The difference between them is how they are designed and how customizable the procedure is. AOK includes all of the different designs available allowing for the best possible results for each unique patient.

It is important to keep in mind that only a qualified licensed eye care practitioner is able to diagnose and determine the best treatment option that is right for you.


  • Children and adults who are active and involved in sports

  • Patients looking for an alternative to LASIK surgery

  • Patients who are too young for LASIK surgery

  • Patients who want to correct their myopia without the use of traditional daytime contacts or glasses

  • Children whose parents want a chance to slow and possibly prevent the progression of their myopia

  • Patients who have difficulties wearing traditional contact lenses because of dry eyes or allergies

How AOK Works

AOK overnight procedure is designed to gently reshape the first few microns of the cornea while you sleep. Once the molds are removed in the morning, the slight change in the curvature of the corneal surface results in clear vision during waking hours thus reducing the dependence on daytime contact lenses or glasses.

The best part about AOK is that it is safe, non-surgical, non-invasive and reversible.

AOK for Athletes and Active lifestyles

No matter what level of sports you or your child are involved in, you want the best vision as possible. Additionally, glasses are a hindrance for any sports enthusiast, whether professional or recreational, and traditional daytime contact lenses are often equally irritating and inconvenient.

Too young or looking for an alternative to LASIK

While surgical vision correction offers the convenience of not having to wear contact lenses or glasses, it is not for everybody:

  • Like any surgery, there is no guarantee of a perfect outcome with LASIK or other vision correction procedures.

  • Like any surgery, there are risks of complications from LASIK and other vision correction procedures. Possible complications include glare and halos around lights, persistent dry eyes and reduced visual acuity or contrast sensitivity.

  • You must be over 18 for most surgical vision correction procedures, eliminating LASIK and related surgeries as options for younger athletes.

Advanced Orthokeratology, on the other hand, is safe, non-surgical, non-invasive and reversible. In fact, AOK is so safe that many orthokeratologists are comfortable performing corneal refractive therapy for children as young as 5 years old.

Additionally, AOK is ideal for athletes who are too young for LASIK. Advanced Orthokeratology can give them good, uncorrected vision for sports throughout their school years.

Because Advanced Orthokeratology is reversible, when a child reaches the age of 25, they have the option of discontinuing their treatment for awhile (allowing their nearsightedness or astigmatism to return and stabilize) and then have LASIK surgery if they no longer want to wear AOK molds overnight.

Correcting Myopia (nearsightedness)

Otherwise known as nearsightedness or shortsightedness, myopia is a condition in which your near vision is clear but distant objects appear blurred to an uncorrected eye. This is due to the eyeball elongating as we grow during early adolescence. The result is a mismatch between the length of the eye and its optical power causing light entering the eye to focus in front of the retina rather than directly on it.

Using AOK Advanced Orthokeratology therapy to gently reshape the cornea re-aligns the optical focal point onto the retina allowing patients with nearsighted prescriptions see clearly all day.


Myopic - Nearsightedness Prevention

In addition to AOK therapy providing nearly immediate results in correcting myopia, several studies also indicate that it helps prevent myopia from worsening in future.

Traditionally, glasses and conventional daytime contact lenses have been prescribed to correct myopia. However, for children, and many adults, this correction does not prevent their myopia from worsening over time thus requiring stronger prescription lenses to achieve the necessary level of correction.

Benefits for Nearsighted Children

Since myopia is often diagnosed at an early age and progressively worsens until late adolescence, early AOK treatment offers a proven, reasonable method to significantly alter the progression of myopia from increasing over time. This is important because, if left untreated, high levels of myopia (nearsightedness) may also create increased risks for other eye diseases such as glaucoma and detached retinas.

By wearing AOK molds (Advanced Orthokeratology), you or your child now have an alternative to glasses or daytime contact lenses that may correct your myopia and prevent nearsightedness progression.

AOK molds are well tolerated by children because while their eyes are closed there is less lid sensation. Additionally, since they will be sleeping in their lenses they will not have to wear corrective lenses during the day. This means they can participate in a variety of activities, including sports, without worrying about glasses or contacts.

Orthokeratology Solution for Dry Eyes and Allergies

Dry eye syndrome has become increasingly prevalent over the past ten years as people spend more time indoors where air-conditioning systems remove moisture from the air. Additionally, the substantially greater time spent staring at PCs, TVs, smart-phones and gaming devices reduces blink rates by up to 80% thus dramatically reducing tear flow to the surface of the eyes. Other common causes of dry eye include the aging process, wearing contact lenses, hormone levels, menopause, birth control, diabetes, environmental factors like allergies, wind, and dry climate, medications, and heavy computer usage. Thus dry eye syndrome has become one of the most common eye health issues and led to the development of a major market for proposed remedies yet it is unclear that any one product offers the best solution.

Additionally, increasing numbers of people are affected by allergies including the seasonal effects of hay fever which can make it almost impossible to continue wearing daytime contact lenses. This is where AOK therapy for dry eyes may offer a new solution since corneal refractive therapy lenses are only worn overnight when sleeping then removed the next morning to give clear natural vision all day long.

Since AOK molds are only worn at night while you sleep, dry eye and allergy sufferers may experience relief due to unrestricted tear flow during waking hours.

Additional Corneal Refractive Therapy Options for Hyperopic and Presbyopic Patients:

While AOK therapy is ideal for the myopic patient, they are not limited for use on myopic patients only. Advanced Orthokeratology also effectively treat patients with Hyperopia (farsightedness) and Presbyopia (the need for reading glasses).

If you have either of these conditions we may still be able to correct your vision with AOK. After a thorough eye examination, Dr. Abraham Zlatin will be able to outline the best options for you.

Orthokeratology Precautions

There is a small risk involved when any contact lens is worn. It is not expected that AOK molds for corneal refractive therapy will provide a risk that is greater than other contact lenses. There were no serious adverse events reported to the FDA in clinical studies.

Only after a thorough eye exam by a licensed physician / orthokeratologist can it be determined if corneal refractive therapy may benefit you. There are no guarantees that any specific treatment will work for all patients. Reduction for any individual patient’s myopia may vary depending on that patient’s corneal variables and overall results may vary so ask Dr. Zlatin if AOK therapy is right for you or your child.
