Corneal Collagen Cross-Linking

Corneal collagen cross-linking is a photochemical procedure approved by the U.S. Food and Drug Administration (FDA) for the treatment of progressive keratoconus and corneal ectasia following refractive surgery. Keratoconus is a dystrophy of the cornea characterized by progressive deformation (steepening) of the cornea, while corneal ectasia is keratoconus that occurs following refractive surgery. Both conditions can lead to functional loss of vision and need for corneal transplantation.
