Cross-linking, also known as CXL or C3R is a procedure for keratoconus or ectasia – a progressive degeneration of the cornea. The aim of CXL is to prevent the corneal shape from deteriorating in the future and is the only treatment currently available to stop your vision getting worse.
Cross-linking uses ultraviolet light in conjunction with vitamin B2 (riboflavin) drops to strengthen the cornea. When used together they cause fibres within the cornea to bond more tightly, which mimics the normal age-related stiffening of the cornea. This is known as natural cross-linking.
Mr Gore leads the Early Keratoconus and Corneal Cross-Linking Service at Moorfields Eye Hospital. He is an expert
on keratoconus and post-LASIK ectasia, an international authority on cross-linking and an opinion leader amongst colleagues.
