Keratoconus does not make people go blind. However the changes to the cornea can make it impossible for the eye to focus without eyeglasess or contact lenses. Keratoconus can be dangerous if laser vision correction surgery (LASIK or PRK) is performed on the eye.
Keratoconus (KC, KTCN) (from Greek: kerato-horn, cornea; and konos cone) is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual curve.
