Orthokeratology, or sometimes also known as ‘OrthoK’ is allows patients to experience clear vision, without the need of wearing glasses or contact lenses, by wearing contact lenses at night in their sleep. It is a great non-surgical alternative to procedures such as LASEK.

How does it work?

The lenses are worn every night for about 6-8 hours. During your sleep, the rigid, gas permeable contact lens temporarily reshapes the top layer of the cornea.  This reduces myopia (short-sightedness), hyperopia (long-sightedness) or astigmatism so that you won't have to wear glasses or contact lenses during the day.

The degree of correction achieved varies depending on your prescription. We can advise on the degree of correction at your appointment.

Is it safe?

If it is properly handled and good hygiene is maintained, it does not pose any extra risk compared to a normal soft contact lens. There is no minimum age for a child to wear these lenses, as long as contact lens care procedures are followed with or without adult supervision.

Does it really stop me from getting more short-sighted?

According to current research, patients with orthokeratology treatment progressed at about 50% of the rate compared to spectacle wearers on average. However, results may vary from person to person as each individual responds differently.
