Treatment of keratoconus at the clinic of Dr. Donate in Lyon.

Keratoconus is an evolutive ocular disease. The cornea (the transparent outer part of the eye) which is normally round and domed becomes thinner to form a cone. The irregularity of the cornea causes blurred vision.
The Cross-Linking (CXL) treatment strengthens the bio-mechanics of the cornea and stops the progression of the keratoconus in the early phases of the disease. This technique involves applying a photo-sensitive solution (riboflavin or vitamin B2) to the cornea and exposing it to a low dose of ultraviolet rays. The solution then reacts with the ultraviolet light to create new collagen bonds across the cornea.
