Keratoconus

Keratoconus is a disorder characterized by progressive corneal steepening, most typically inferior to the center of the cornea, with eventual corneal thinning, induced myopia, and astigmatism. Treatment consists of spectacles for astigmatism and myopia initially, and rigid contact lenses. Once contact lenses comfort becomes inadequate the surgical treatment with intracorneal rings is indicated. When the thinning is very important or if the cornea is cloud, the treatment is a corneal transplant.
