Prosthetic Contact Lenses Prosthetic contact lenses can significantly improve the cosmetic appearance of a disfigured or scarred eye, whether from previous trauma or serious eye infection. An initial examination can help your eye doctor determine the likelihood of a desirable outcome with a prosthetic contact lens. In some cases, it’s possible to obtain a satisfactory result just with disposable cosmetic contact lenses. In other situations, if the of eye shape will not provide on-eye stability of the prosthetic contact lens, you will be referred elsewhere for what’s called a prosthetic scleral shell. If your eye has been removed (enucleated), you will also be directed elsewhere for a custom ocular prosthesis.
