Orthokeratology, also known as (Ortho-k), is a non-surgical technique for treating myopia, or nearsightedness, and can be a suitable alternative to lasik eye surgery that enables myopic condition patients to see better at a distance.

The process uses a series of more rigid contact lenses to reshape the cornea at night and provide a temporary reduction of myopia during the day. These special contact lenses apply pressure to the sides of the cornea and change their shape overnight.

Depending upon the individual patient, a programmed application of different contact lenses may be used. Results are dependent on the individual circumstances however selected patients can go through the whole day wearing no vision correcting prescription glasses or contact lenses.
