Three types of corneal transplants
The cornea, the transparent front “window of the eye”, is responsible for about two thirds of the focusing power of the eye.
Corneal tissue can become damaged through disease or trauma. This damage can cause scar tissue and opacities in the normally-clear cornea, resulting in a reduction in visual acuity.
If the cornea develops visually significant opacities or irregularities, a corneal transplant procedure can be performed. A corneal transplant involves replacing a diseased or scarred cornea with a new cornea or specific corneal layers tissue.
