Keratoconus is a condition where the cornea is “cone-shaped” instead of round or dome-like. The irregular cornea will bend light in different directions, creating visual distortion. Keratoconus is a degenerative disorder where symptoms usually become noticeable in the late teens and early twenties. Initial treatments include hard contact lenses which help the cornea maintain a more round shape and bring light into better focus. Some cases of keratoconus progress rapidly for ten to twenty years before ceasing. If the condition progresses, the cornea thins and may require surgery. Common symptoms of keratoconus include blurred vision, light sensitivity, and glare.
