Corneal Disease and Transplants
Corneal erosion affects the cornea, the clear dome covering the front of the eye. The outermost layer of the cornea is the epithelium. When the epithelium does not stay attached correctly to the corneal tissue below, this can cause a condition called corneal erosion.
A healthy, clear cornea is necessary for good vision. Scars, swelling or an irregular shape can cause the cornea to scatter or distort light, resulting in glare or blurry vision.
A corneal ulcer is an open sore on the cornea.
