Do your contact lenses bother you throughout the day? Are you tired of wearing glasses? Are you unsure about LASIK? Then orthokeratology may be right for you!
Orthokeratology (Ortho-K) is the science of changing the curvature or shape of the cornea to affect how light is focused on the retina at the back of the eye. Ortho-K achieves this change using a contact lens that is worn while you sleep. The cornea is responsible for most of the eye’s corrective power and contributes to various conditions such as nearsightedness (myopia), farsightedness (hyperopia), and the blur of astigmatism.
Ortho-K was discovered more than 40 years ago when doctors noticed that their hard contact lens patients saw better after taking their lenses out than they did prior to putting them in. This concept was applied to new lens designs and Ortho-K eventually received FDA approval. Today, Ortho-K is approved for children of all ages as well as adults.
Ortho-K involves the fitting of a specialty rigid gas permeable contact lens that is worn overnight. This retainer lens will gently change the shape of your cornea. Upon wakening, the lens is removed and your vision will be clear throughout the day. The retainer lens will need to be worn most nights, although some patients can achieve clear vision with less frequent wear.
The best part about Ortho-K is that it is a non-surgical, non-invasive, completely reversible vision treatment.
