Riboflavin Mediated Corneal Crosslinking for Stabilizing Progression of Keratoconus

Riboflavin Mediated Corneal Crosslinking for Stabilizing Progression of Keratoconus

Background: Corneal cross linking is a procedure that induces collagen cross linking of the corneal stroma due to release of reactive oxygen radicals upon activation of topically applied riboflavine A by UVA exposure. This procedure might be capable of reducing keratocouns progression.

Purpose: Although there are no randomised controlled trials on the effectiveness of corneal cross linking for the treatment of keratoconus it gains more and more importance in the general clinical setting. Therefore, the investigators started such randomised, placebo controlled, double blinded, multicenter trial to find out if this treatment is as effective as it promises to be.

Methods: Randomised, placebo controlled, double blinded, multicenter trial.
