Orthokeratology

What is Orthokeratology?

Orthokeratology, (available now from our Auckland clinic) is a safe, non-surgical 'while you sleep' solution for short sightedness, far sightedness, and astigmatism. Wearing specialised rigid gas-permeable contact lenses (RGPs) overnight, the cornea of the eye is reshaped whilst you sleep to reduce myopia, and in some cases hyperopia and astigmatism.

Effects usually last 10 - 12 hours after waking, so patients wear retainer lenses each night to maintain effects. The procedure is  widely considered a safe (and reversible) alternative to refractive surgeries such as LASIK, LASEK, RK, PRK, and ALK.

This is ideal for sports, swimming, and other physical activities. It can be a wonderful solution for sufferers of hay-fever allergies that wear contact lenses during the day. The main goal of Ortho-K (also known as OK lenses) is to try to alleviate the need for glasses, contact lenses, or laser surgery.
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.
