Keratoconus
Keratoconus is a corneal disease in which the regular shape of the cornea becomes more conical and it becomes thinner as well. This condition can be managed better if detected earlier by corneal topography / tomography. It usually affects both eyes, although one eye is usually affected more than the other. If there is delay in detection or treatment of keratoconus, it can result in significant deterioration of vision.
