For patients that have issues with irregular astigmatism caused by Keratoconus treatment options have been few and far between. Typically your eye doctor could fit you with special contact lenses or if the condition progresses enough a corneal transplant would be indicated. There has been research into better options of treatment for progression and finally the FDA has approved a treatment option called corneal cross-linking.
This treatment takes a specific formula that includes Riboflavin (Vitamin B2) and bathes the eye in the solution. UV light is then used to activate the solution. The collagen fibers in the cornea will strengthen and stiffen. The goal of the treatment is to improve those collagen fibers so they can become more regular and in turn which can stop the progression of Keratoconus. The treatment has been around for many years in Europe and the studies have shown the safeness and effectiveness it can have.
