Keratoconus is a non-infectious eye condition in which an individual’s normally round cornea progressively thins and becomes cone shaped. This irregularity causes images to be distorted when projected onto the retina, resulting in siginificant visual impairment. Keratoconus generally affects both eyes, though one eye will typically advance more quickly than the other. The incidence of Keratoconus has been reported to affect 1 out of every 2,000 people and is often diagnosed in patients in their late teens. Males, females, and all ethnicities are affected equally.
In the early stages of Keratoconus, glasses or soft contact lenses may be used to correct any vision issues. As the cornea progressively thins and bulges into a more cone-like shape, rigid gas permeable (RGP) lenses are often needed to provide a clear surface in front of the cornea, allowing the light rays to be projected clearly to the retina. For many years, this was the main treatment option for keratoconus patients until they eventually required a corneal transplant.
There are now new treatment options available, including Corneal Collagen Cross-linking and Intacs®.
