Corneal Transplants Performed at Our Jacksonville, FL Practice
The cornea is the clear tissue in the front part of the eye. It is made of three primary layers: the Epithelium, the corneal stroma, and the Endothelium. The epithelium is a thin surface layer. The stroma is a thick transparent middle layer composed of collagen fibers. The endothelium is a single layer of specialized cells that pumps fluid out of the corneal stroma and keeps it clear. Too much fluid in the stroma can cause swelling of the cornea and decreased vision.
