Corneal collagen cross-linking is the procedure to promote cross-linking between collagen fibres within the cornea, to halt to progression of the ectatic disease. The procedure is accomplished by installing Riboflavin (vitamin B2) drop in the eye then focusing the ultraviolet light on the eye for 10 minutes. Following the procedure a bandage contact lens is used to control the pain and the patient is checked next day in the eye clinic to check for surface healing.
