Keratoconus

Keratoconus

This degenerative disease occurs as a result of genetically weak cornea which, usually during puberty, becomes progressively more curved than normal. Over time, this leads to an increase in the unevenness of the cornea, a considerable increase in refractive power, most probably astigmatism, and blurred vision.
In the first stages, afflicted patients can wear glasses to ensure relatively good eyesight, while in more advanced cases, in higher degrees of corneal distortion, medium-hard or hard contact lenses are mandatory. In around 20% of cases, patients have to undergo a corneal transplant (keratoplasty) to restore uniformity and normal eyesight with the help of glasses or contact lenses.
