Orthokeratology is a safe, non-surgical and reversible procedure of using rigid contact lens to temporarily reshape the cornea, with the purpose of reducing myopia (short sightedness) and eliminating the need to wear correcting spectacles or contact lenses during the day.

A rigid contact lens is worn at night, to gently flatten the front of the eye and reshape the cornea to the correct shape for focused vision the following day. The effect is stable but not permanent, and without the lens in place the cornea will slowly return to its original shape over a few weeks.

Orthokeratology is not painful although there will be some awareness of the lenses at the beginning of treatment. The lenses will not be felt when asleep.

The fitting process requires multiple high quality topographical scans to be taken of the cornea of each eye. A custom designed lens is then ordered and fitted to each eye. This session also involves teaching lens care and correct insertion and removal techniques.

Initially, multiple aftercare sessions are required over the first few months to ensure that the contact lens fit is correct, the eyes remain healthy and that good vision is being achieved.
