This is a progressive condition that causes the cornea to become thinner and eventually bulge forward in a cone-like shape. The result is increasingly distorted vision that cannot be corrected with eyeglasses or soft contact lenses.
There are a variety of semi-rigid oxygen permeable lens designs that fit different types of keratoconus, and all of them do an excellent job of providing clear vision by negating or compensating for the distortion of the cornea. Sometimes, we will fit a combination of semi-rigid and soft contact lenses, a method called "piggy-back lenses".
Unfortunately, in many cases, the ultimate progression of this condition results in corneal scarring, and eventually a corneal transplant is the only treatment.
