Keratoconus
Keratoconus is a condition in which the cornea of the eye is "cone shaped". A normal cornea has a smooth, regular curvature which resembles a section of a sphere or, in cases of astigmatism, somewhat the shape of a spoon. The keratoconic cornea with its cone-like bulge has an irregular shape, and in its moderate to advanced states causes blurred, distorted vision which cannot be properly corrected by regular glasses.
