Corneal collagen crosslinking is a process used to strengthen the cornea and halt any further progression of the keratoconus.
It works by soaking the cornea in a riboflavin solution that contains vitamin B and exposing the eye to ultraviolet radiation. The UV light activates the riboflavin and encourages the creation of collagen bonds, or cross links. These bonds are responsible for preventing the cornea from protruding further progressing the condition. Crosslinking is not a cure for keratoconus and glasses or contact lenses would still be required after the procedure. However, it is a proven method to halt any progression of keratoconus and prevent any further loss of vision or the need for corneal transplant.
