Examples of such conditions include keratoconus or corneal scarring. Made of a rigid, gas-permeable material, they vault over the cornea and fit over the white part of the eye, the sclera.
Ortho-k lenses are special custom-made contacts designed to reshape the cornea while the patient sleeps. Most users experience a little discomfort when they start wearing the lenses, but comfort improves as the cornea reshapes.
Scleral lenses offer a nonsurgical solution for patients with astigmatism. They provide excellent vision correction for people with irregular corneal curvature. Unlike regular soft contacts that lie directly on the cornea, scleral lenses rest on the white of the eye, the sclera.
