'''[[Keratoconus]]''' (from [[Greek language|Greek]]: ''kerato-'' horn, cornea; and ''konos'' cone), is a degenerative non-[[inflammation|inflammatory]] disorder of the [[human eye|eye]] in which structural changes within the [[cornea]] cause it to thin and change to a more [[Cone (geometry)|conical]] shape than its normal, gradual [[curve]]. Keratoconus can cause substantial distortion of [[Visual perception|vision]], with multiple images, streaking and [[photophobia|sensitivity to light]] all often reported by the patient.
