What is Ortho K?


Orthokeratology or Corneal Refractive Therapy (CRT) is the art and science of the temporary elimination of myopia (short-sightedness) with specialist contact lenses.

Doctor Alex Levit has been practicing orthokeratology since 1995, and is certified to use a variety of ortho-k lenses [moulds] including fully custom-made ortho-k designs. Dr Levit is a certified specialist in all medical contact lens modalities; these include specialist corneal rigid lenses, a variety of hybrid lens designs, large corneal, semi-limbal and scleral lenses.


How does it work?


These lenses are worn during sleep overnight and removed in the morning. These lenses alter the shape of the front of the eye (cornea) which is elastic in nature, by the exact amount required to eliminate the myopia of the eye.

Is it safe?


This process is safe, FDA approved and fully reversible. If the therapy is successful the need to use glasses and lenses during the day is removed.
