Corneal cross-linking

At Dr Ioannides Laser Eye Clinic we use corneal collagen cross-linking (CXL) as a means of strengthening a weakening and thinning cornea. The commonest cause of a weakened and thinned cornea is called keratoconus.

Cross-linking is a medical procedure that combines the use of ultraviolet (UV-A) light and riboflavin (vitamin B2). Riboflavin eye drops are instilled onto the cornea and then the cornea is exposed to ultraviolet light. The light causes the riboflavin to fluoresce, which leads to the formation of stronger bonds between corneal molecules resulting in a structurally stronger cornea.

At Dr Ioannides Laser Eye Clinic the chief aim of cross-linking is to arrest the progression of keratoconus, treat the progressive vision loss and prevent a corneal transplantation.
