About Keratoconus
Keratoconus (KC) is a thinning of the central zone of the cornea. As this progresses, normal eye pressure causes the round shape of the cornea to distort and a cone-like bulge develops, resulting in significant visual impairment.
Symptoms blurring and shortsightedness, light sensitivity, halos and ghosting around light sources that can make night driving difficult.
Treatments spectacles in the early stages. Then contact lenses, usually rigid. Corneal crosslinking may slow or halt progression; corneal transplants used in a small number of severe cases.
