Keratoprosthesis

Keratoprosthesis is a surgical procedure where a diseased cornea is replaced with an artificial cornea. Traditionally, keratoprosthesis is recommended after a person has failed one or more donor corneal transplants.

History[edit | edit source]

The concept of keratoprosthesis dates back to 1789, when French physician Pellier de Quengsy first proposed the idea. However, it was not until the 20th century that significant advancements were made in the field.

Procedure[edit | edit source]

The procedure involves the removal of the central portion of the diseased cornea, followed by the insertion of the artificial cornea, which is sutured into place. The artificial cornea, or keratoprosthesis, is typically made of clear plastic with excellent tissue compatibility and clarity.

Types of Keratoprosthesis[edit | edit source]

There are two types of keratoprosthesis: temporary and permanent. Temporary keratoprosthesis is used as a part of a two-stage procedure, while permanent keratoprosthesis is designed to stay in the eye indefinitely.

Complications[edit | edit source]

Possible complications of keratoprosthesis include glaucoma, retinal detachment, and infection. Regular follow-ups with an ophthalmologist are necessary to monitor for these potential complications.

Future Developments[edit | edit source]

Research is ongoing to develop a bioengineered cornea that can integrate with the patient's own cells. This would potentially eliminate the risk of rejection that comes with donor corneal transplants.
