Keratoconus is an uncommon condition in which the normally round, dome-like cornea (the clear front window of the eye) becomes thin and develops a cone-like bulge. Keratoconus literally means “cone-shaped cornea.” The cornea is a very important part of your eye. Light enters the eye through the cornea, which refracts, or focuses, the light rays so that you can see clearly.
Treatment usually starts with new eyeglasses. If eyeglasses don't provide adequate vision, then contact lenses, usually rigid gas permeable contact lenses, may be recommended. With mild cases, new eyeglasses can usually make vision clear again.
The extrapolated prevalence in Finland, is found to be 2,607 for two times of 5,214,512 population estimation used. Ongoing Research is being done at Keratoconus Centers.
