The cornea is the clear dome-shaped structure in the front of the eye. It is the first point at which light enters the eye and is refracted. While the cornea plays a critical role in the patient’s vision, many diseases can alter its function causing pain, irritation, tearing or blindness. The cornea can be reshaped during the LASIK procedure and can reduce a patient’s need for eyeglasses.

The cornea itself has 5 main layers including the Epithelium, Bowman’s layer, the Stroma, Descemet’s membrane and the Endothelium. Each of these layers can develop abnormalities.
