The cornea is the clear, dome-shaped surface covering and protecting the front of the eye. It transmits light to the interior of the eye, allowing you to see clearly. The cornea is responsible for a large part of the eye’s focusing power.

Injuries and diseases, sometimes hereditary, can cause clouding, distortion, or scarring of the corneal tissue. The result, depending on the nature and extent of the problem, may be reduced vision, pain, sensitivity to light, redness, tearing, and inflammation.

Diseases of the cornea refers to a wide range of conditions that affect the cornea, including:

• Infections and inflammation of the cornea
• Inherited corneal diseases
• Ocular surface diseases
