Keratoconus creates visual symptoms by causing thinning and irregular bulging of the cornea. Keratoconus literally means cone-shaped cornea.
The cornea is the most important refractive element of your eye. As light enters the eye, it refracts, or focuses, the light rays so that you can see clearly. In the case of keratoconus, the light entering the eye not evenly bent resulting in a blurred and distorted image. Some patients have described this as looking through a bumpy piece of glass.
According to the National Keratoconus Foundation, about 1 out of 2000 individuals will be affected by keratoconus. Most cases of keratoconus are discovered in adolescence or young adulthood. When the blur from unusual degrees of astigmatism prompt an eye examination – and symptoms generally worsen over time. It is believed that an abnormality of the connective tissue that composes the cornea allows progressive thinning and stretching of the cornea, allowing it to curve outward like a cone rather than a normal spherical shape. Rigid gas permeable contact lenses are generally used in this stage to allow correction. If the disease progresses even further and contact lenses become inadequate, the next step may be a corneal transplant surgery.
