Ocular Prosthesis: An Overview

An Ocular Prosthesis

An ocular prosthesis, also known as an artificial eye or glass eye, is a type of craniofacial prosthesis that replaces an absent natural eye following enucleation, evisceration, or orbital exenteration. This article provides a comprehensive overview of ocular prostheses, including their types, manufacturing, fitting, care, and the role of ocularists.

Definition and Purpose

An ocular prosthesis is designed to fit over an orbital implant and under the eyelids, replacing the physical appearance of the natural eye without restoring vision. It is essential for aesthetic and psychological reasons, helping individuals maintain a natural facial appearance.

Types of Ocular Prostheses

There are two primary types of ocular prostheses:

• Standard Ocular Prosthesis: Typically made of medical-grade plastic acrylic, shaped like a convex shell.
• Scleral Shell: A thin, hard shell worn over a damaged or eviscerated eye.

Manufacturing and Materials

Manufacturing Process of Ocular Prosthesis

While traditionally made of glass (cryolite glass), most modern ocular prostheses are made from medical-grade acrylic due to its durability and lightweight properties.

Role of Ocularists

Ocularists are skilled professionals specializing in the fabrication and fitting of ocular prostheses. They ensure that each prosthesis is custom-made to fit the patient’s ocular socket and matches the color and appearance of the natural eye.

Fitting and Customization Process

The fitting process involves:

• Taking an impression of the ocular socket.
• Custom painting the prosthesis to match the natural eye.
• Ensuring a comfortable and precise fit for optimal cosmetic appearance.

Care and Maintenance

Proper care is crucial to maintain the appearance and longevity of the prosthesis. This includes regular cleaning and periodic visits to the ocularist for adjustments and polishing.

Psychological and Social Aspects

An ocular prosthesis can significantly impact a person's psychological well-being and social interactions. Adjusting to life with a prosthesis often requires support and counseling.
