Orthokeratology is a treatment for patients who wish to enjoy their day without glasses or contact lenses. The patient wears a lens mold that gently changes the cornea so the prescription is reduced. In the morning the molds are removed an the patient can see clearly without glasses and contact lenses.
The lenses are comfortable and do not interfere with sleep. They last approximately a year and are worn as long as myopia progression is considered a risk or until freedom from daytime lens correction is no longer desired.
Patients with mild to moderate levels of myopia, with or without mild amounts of astigmatism, may be a good candidate for ortho-k. The ability to correct farsightedness and presbyopia will be available soon too. Even patients who are as young as 7 years old can be great candidates, which makes orthokeratology a great alternative to LASIK vision correction.
See Clearly Without Glasses, Contacts or Surgery
Ortho-k safely and gently changes the shape of the cornea while then retainers are worn. Rarely do patients have problems with comfort of the lenses since they are put on just a few minutes before going to bed. You can even see clearly while the lenses are worn. When the lenses are removed, the cornea maintains the new shape throughout the day. Corneal topography will show a LASIK-like flattening of the central cornea which allows the patient to see clearly.
Orthokeratology is a great treatment for myopia control, usually reducing myopic progression by about 50%. For patients who have a sincere desire to keep myopic progression to an absolute minimum we can combine it with medical treatment also. Ortho-k is the preferred treatment for patients who are extremely active in sports since there is no need for glasses or contacts during the day.

Frequently Asked Questions About Orthokeratology
Is orthokeratology safe?
Over the past 40 years OrthoK has been tested worldwide on hundreds of thousands of patients in every age group. Numerous studies have been conducted evaluating all aspects of the procedure.
How is orthokeratology different than LASIK?
No surgery is involved in OrthoK. Where OrthoK is fully reversible, Lasik is not. Lasik is permanent surgery involving tissue removal with risks of scarring or weakening of the cornea. OrthoK, on the other hand, involves gentle vision shaping using special contact lenses with little risk of scarring.
How are orthokeratology lenses different than regular contacts?
Unlike a standard contact lens, the orthokeratology contact lens is specially curved to exert a gentle pressure on the eye to reshape it, resulting in improved vision. In addition, sophisticated design technology is used to measure thousands of points on an eye’s surface and customize the orthokeratology lens to fit the unique shape of each patient’s eyes.
Who is NOT a good candidate for orthokeratology?
Not everybody can be a candidate for orthokeratology. orthokeratology requires a healthy cornea without significant scars or other problems. Poor hygiene, inability to handle the lenses, severe dry eye, inflammations, infections and other problems may all prevent successful treatment. orthokeratology is a challenge for those with very high levels of myopia or those who are farsighted (hyperopic) but experienced doctors have shown very good results with these conditions. If you are nearsighted or have astigmatism, the odds are in your favor that you are a candidate.
