Keratoconus is a progressive eye condition that causes the cornea to thin and bulge out like a cone. The cornea is the front surface of the eye and serves as a clear window that focuses light onto the back of the eye allowing us to see clearly. As keratoconus progresses and the cornea changes shape, light rays are no longer in focus causing symptoms of blurry vision, glare, and distortion. Keratoconus usually affects both eyes and generally begins to fist affect vision around ages 10 to 25. The diagnosis of keratoconus is made through corneal topography that is done in the office. Corneal topography maps the front of the eye showing any irregularities and changes in shape.

In the early stages of keratoconus, it is possible to correct vision using glasses and soft contact lenses. As the condition worsens, glasses and soft lenses will not be effective. At this point, it is recommended that patients are fit in rigid gas permeable contact lenses or scleral lenses to obtain the best possible vision. Unlike glasses and soft contact lenses, these
specialty lenses create a smooth front surface that acts as a new cornea and allow for normal vision.
