Corneal dystrophy is a rare, inherited corneal disease in which one or more parts of the clear outer layer of the eye (cornea) lose their normal clarity as a result of cloudiness. Some people with corneal dystrophy may have no symptoms, while others may have significantly impaired vision.

The eyelids play a very important role in the aesthetics and function of the eyes. Eyelid dehiscence is a condition in which the eyes are not completely protected by the opening and closing of the eyelids. The risk of eyelid dehiscence, if not detected and treated, will seriously affect the patient's vision.
