If you are looking to wear contact lenses but have always had problems with comfort or have been told you’ll never be able to wear contact lenses because of an irregularly shaped cornea or other eye problem, it may be time to look into a type of contact lens known as a “scleral lens.”
Scleral contact lenses are large diameter rigid gas permeable contact lenses designed to pass over the cornea entirely, resting comfortably on the white of your eye, also known as the sclera. This allows scleral lenses to essentially replace the irregular surface of the cornea with a perfectly formed optical surface.
This gives you the kind of perfectly crisp vision you may not even be able to accomplish at all with eyeglasses or other forms of vision correction. This extra area also allows the lens to be a liquid reservoir to provide extra comfort for those who otherwise may have comfort issues with regular contact lenses.
