Ocular Prosthesis

An ocular prosthesis, also known as prosthetic eye, artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an operation that removes the eye. The prosthesis fits over an orbital implant and under the eyelids. An ocular prosthesis roughly takes the shape of a convex shell and is made of medical grade plastic acrylic.

An ocular prosthesis does not provide vision which would with a visual prosthesis. A person with an ocular prosthesis is totally blind on the affected side and has monocular or one sided vision.

Ocular Prosthesis

Ocularists and eye surgeons have always worked together to make artificial eyes look more realistic. For decades, all efforts and investments to improve the appearance of artificial eyes have been dampened by the immobility of the pupil. One solution to this problem has been demonstrated recently in a device based on an LCD which simulates the pupil size as a function of the ambient light.
