Normal Cornea vs Stages of Keratoconus Cheat Sheet
Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision.
Keratoconus causes increasing blurriness and shortsightedness in vision, light sensitivity and halos and ghosting around light sources.
