Ocular Prosthesis

What Is an Eye Prosthesis?

An eye prosthesis, often referred to as an artificial eye, is a device used to replicate the appearance of a natural eye when one is lost or damaged beyond repair. The prosthesis does not restore vision but serves to fill the eye socket, improve facial symmetry, and provide a natural look for those who have undergone enucleation (surgical removal of the eye) or evisceration (removal of the eye’s contents while keeping the sclera intact).

Ocular prostheses are custom-designed to match the patient’s remaining eye, ensuring that the size, shape, color, and iris pattern align as closely as possible. Prosthetic eyes are created by specialized ocularists who work closely with patients to craft a prosthesis that blends seamlessly with their appearance.

Types of Ocular Prosthesis

There are several ocular prosthesis types depending on the patient’s condition, the extent of eye removal, and the materials used to create the prosthetic. These include:

1. Stock Prosthesis
   A stock prosthesis is a pre-made artificial eye that comes in various standard sizes, shapes, and colors. While stock prostheses are readily available and less expensive than custom-made options, they may not provide a perfect match to the patient’s other eye. Stock prostheses are often used as a temporary solution before a custom prosthesis is made.
2. Custom-Made Prosthesis
   A custom-made eye prosthesis is designed specifically for the patient, with careful attention paid to every detail to match the remaining natural eye. This type of prosthesis offers the best cosmetic result as it is individually molded and colored to fit the patient’s eye socket and replicate the unique appearance of their other eye. Custom prostheses are generally more expensive but provide superior comfort and realism.
3. Scleral Shell Prosthesis
   For patients who still have their natural eye but have experienced significant damage or loss of vision, a scleral shell prosthesis may be recommended. This is a thin, hollow prosthetic that fits over the existing eye, restoring the appearance of the eye without requiring enucleation. Scleral shell prostheses are also custom-made to ensure a perfect fit and natural look.
4. Silicone Eye Prosthesis
   One of the most advanced and popular types of prosthetic eyes is the silicone eye prosthesis. Silicone is a flexible, durable material that mimics the natural texture and movement of the eye more effectively than other materials. Silicone eye prosthesis is often preferred for its lifelike appearance and the fact that it is comfortable for long-term wear, making it a popular choice for many patients. Additionally, silicone prostheses are lightweight and hypoallergenic, reducing irritation and discomfort in sensitive eye sockets.
