Advantages include less risk of infection, less discomfort and one-day visual recovery.Ĭurrently, the only corneal cross-linking platform that is FDA-approved for the treatment of progressive keratoconus in the U.S. With the epithelium-on method (also called transepithelial crosslinking), the corneal epithelium is left intact during the treatment. With epithelium-off crosslinking, the outer layer of the cornea (called the epithelium) is removed to allow entry of riboflavin, a type of B vitamin, into the cornea, which then is activated with UV light. There are two versions of corneal crosslinking: epithelium-off and epithelium-on. (Diagram: Boxer Wachler Vision Institute) The aim of corneal cross-linking is to strengthen the cornea by increasing the number of 'anchors' that bond collagen fibers together. This procedure, also called corneal collagen cross-linking or CXL, strengthens corneal tissue to halt bulging of the eye's surface in keratoconus. Treatments for progressive keratoconus include: 1. But as the disease progresses and the cornea thins and becomes increasingly more irregular in shape, glasses and regular soft contact lens designs no longer provide adequate vision correction. In the mildest form of keratoconus, eyeglasses or soft contact lenses may help.

Risk factors for oxidative damage and weakening of the cornea include a genetic predisposition, explaining why keratoconus often affects more than one member of the same family.

This imbalance makes the cornea more susceptible to oxidative damage from compounds called free radicals, causing it to weaken and bulge forward. Research suggests the weakening of the corneal tissue that leads to keratoconus may be due to an imbalance of enzymes within the cornea. Often, keratoconic patients experience changes in their eyeglass prescription every time they visit their eye doctor. Glare and light sensitivity also may occur. Keratoconus signs and symptomsĪs the cornea becomes more irregular in shape, it causes progressive myopia and irregular astigmatism to develop, creating additional problems with distorted and blurred vision. Keratoconus can occur in one or both eyes and often begins during a person's teens or early 20s. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape.
