Orthokeratology is the process of reshaping the cornea in order to improve vision. This practice has been in use ever since the early 1940s, but it was said that such process of vision correction could lead to many unpredictable results. While others believe that it is the best process of eye treatment, there are other individuals who think the other way around. Yet, some medical experts persisted on developing Orthokeratology, and thus, came up with designing effective gas-permeable contact lenses where patients can only wear the contacts at night so as to restructure the cornea and improve vision.
FDA Approved the Use of Orthokeratology
Orthokeratology has become more and more popular, especially among patients who do not want to wear eyeglasses, and prefer to correct their vision through surgery. In 2002, the US Food and Drugs Administration (FDA) has consented the use of corneal reshaping implement known as the “corneal refractive therapy”, which led also to the approvals of several orthokeratology contact lens designs, since a lot of companies came up with their own versions of vision correction products.
Made of Special Gas Permeable Lens
The contact lenses for orthokeratology are made of a special gas-permeable lens that is designed to move the epithelial cells on the corneal surface of the eyes and restructure it. It was said that the material and the design of these lenses played a very important role in coming up with a positive result. Even a minor mistake on the design and material of the lens could lead to complications to the eyes during the treatment. This is the reason why the approval of FDA is very necessary before these products will be manufactured and be sold in the market for public use.
