Corneal Disease

The cornea is the clear, transparent tissue at the front-most part of the eye, functioning as the window to the eye. The cornea, together with the natural lens inside the eye, refract (or bend) light coming from the outside world and refocus them onto the retina for a clear image. Therefore, any disease or process that interferes with the cornea may interfere with this light-bending process and blur one’s vision.

Corneal diseases result from many causes ranging from infectious, inflammatory, structural, and traumatic origins. A few examples are illustrated below. If you have a corneal disease that adversely affects your sight, please see our fellowship-trained cornea specialist for a medical consultation. Some corneal diseases may cause irreversible vision loss if not treated in a timely manner.

The normal cornea can also be artificially manipulated to change its refractive properties to improve a person’s vision. This is the concept behind LASIK and PRK. For more information please click here to view our LASIK page.

Cataracts. See everything
as it should be.

Cataracts are an opacity, or clouding, of the lens of the eye. The prevalence of cataracts increases dramatically with age. In fact, according to the National Eye Institute (NEI), more than half of all Americans age 80 and above either have a cataract or have had cataract surgery. Cataract surgery is one of the safest and most common performed surgeries in the United States.
