Orthokeratology

THE PROCEDURE

• After a preliminary consultation in which the optometrist will assess the general health and likely effectiveness of the patient, measurements will be made of the cornea, and lenses ordered. When they arrive, customer is assisted with fitting them the first time.

• Most of the visual changes occur rapidly in the first few days and weeks of use, requiring frequent examinations. Stabilisation procedures then follow at a slower pace over the next few months. The program length varies between three and six months, depending upon the degree of visual error and the rates of change.

• After maximum results are achieved, Orthokeratology lenses are worn to stabilise the new corneal shape. These are typically worn full time initially and can be reduced to several nights wear, but this varies from patient to patient. Failure to wear the Ortho-K lens on an ongoing basis will result in the return to the pre-existing prescription. 
Ortho-K patients are reviewed on a six-monthly basis.
