Our corneas naturally contain cross-links between collagen fibers in order to maintain shape and strength. Ectasia is a result of not enough of these cross-links to support the cornea, leading to bulging and protrusion. This innovative procedure utilizes a combination of riboflavin and UV light to create additional cross-links to promote cornea stability and strength. The corneal collagen fibrils are chemically bonded together to halt the thinning process and restore vision acuity. This procedure does not involve surgical incision into the eye or ablation, as it is only minimally invasive. Clinical trials have demonstrated that the strengthening effect may be permanent.
