KERATOCONUS

Keratoconus is a progressive eye disease in which the normally roundcornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision.

Keratoconus can occur in one or both eyes and often begins during a person's teens or early 20s.

Keratoconus Symptoms and Signs

As the cornea becomes more irregular in shape, it causes progressive nearsightedness and irregular astigmatism to develop, creating additional problems with distorted and blurred vision. Glare and light sensitivity also may occur.

Often, keratoconic patients experience changes in their eyeglass prescription every time they visit their eye care practitioner.

Keratoconus Treatment

In the mildest form of keratoconus, eyeglasses or soft contact lenses may help. 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.

Intacs

A method for flattening the cornea that is too steep and making a patient more contact lens tolerant is the insertion of  INTACS into the cornea. This procedure is good for patients who are contact lens intolerant and who want to avoid a corneal transplant and whose K readings are not in excess of  58 Diopters. It is also useful for individuals with keratoconus who want to improve their present vision with or without contact lenses.

Corneal crosslinking

 This procedure, often called CXL for short, strengthens corneal tissue to halt bulging of the eye's surface in keratoconus.
