The process of Orthokeratology involves using specialized contact lenses to reshape your cornea. As your cornea changes shape, refractive errors that cause myopia/hyperopia/astigmatism are corrected.
Patients following our orthokeratology program wear their corrective lenses at night while they are sleeping. Because of this, they are generally not required to wear corrective lenses during the day.
Your cornea will undergo a period of rapid adaptation once you begin following the treatment program- typically within a few hours or days.
After 2-3 weeks your cornea will have completed its full adaptation. Ongoing treatment will ensure long-lasting vision correction.
Over 90% of Qualified Candidates for Ortho-K See Improvement to 20/40 or Better
When treatment is maintained, over 65% of patients achieve 20/20 eyesight again. The vast majority achieve at least 20/40, which is the minimum necessary for driving without the aid of corrective lenses like glasses or contacts.

Ortho-K is considered very safe. However, like any treatment, there is the small potential of some side effects being experienced by a small percentage of people undergoing Ortho-K treatment.
These side effects commonly resolve before the end of the first month of treatment. As well, the above risks can be mitigated effectively via a comprehensive fitting measurement/application process.
Orthokeratology is effective up to -6.00 diopters (for myopia) and a maximum of 1.75 diopters (astigmatism).
Orthokeratology is also known as Ortho-K and Corneal Refractive Therapy (CRT). The oxygen permeable contact lenses used in Ortho-K treatment gradually flatten the cornea, improving vision.
Orthokeratology is completely reversible- simply discontinue treatment and your eyes will return to their pre-treatment state over the span of a couple of weeks.
