What is Keratoconus?
Keratoconus is a disease that affects the front clear part of your eye called the cornea. The cornea plays a very important role in the focus of the eye. Keratoconus occurs when there are weak areas that cause thinning of the cornea. When the cornea thins, it often causes a protrusion of the cornea that leads to an irregular shape. This irregular shape is very difficult to correct with glasses.
Progression of the disease can result in loss of vision in which case corneal transplantation may be needed to your restore sight. This poorly understood disease typically affects both eyes with eye one being more severely affected than the other.
