what is keratoconus?!
Question: cornea topography
Answers:
Keratoconus, or "conical cornea" (from kerato- cornea and conus cone), is a degenerative non-inflammatory disorder of the eye in which the cornea thins and changes shape to become more conical than its normal parabolic curve. Keratoconus can cause the vision to become distorted quite badly, with "ghosting", "streaking", and sensitivity to light all often reported.
Keratoconus and the associated vision loss, if in both eyes, can affect the person's ability to, for example, legally drive a car. In most cases, corrective lenses are effective enough to allow the patient to still drive a car and likewise function normally. Further progression of the disease may lead to a need for surgery. There is no known cure for keratoconus, nor can its natural progression be significantly arrested, but it can be successfully managed by means of corrective lenses or surgery.
