Production of the Prosthetic Eye
-
A prosthetic eye can be produced either after removal of the eye by the physician or can be placed on the patient’s phitisic (shrunk) eye.
-
If a surgical intervention is to be considered, production process of the artificial eye can begin at the end of a postoperative period of time determined by the physician (usually after 1-1.5 months which is a length of time required for the socket to heal).
-
The first step is to take an impression of the socket after insertion of one drop of anesthetic. The impression paste injected into the socket hardens in a few minutes and becomes elastic like soft rubber, thereby allowing a precise assessment of the shape of the socket. This stage is not painful, only a slight pressure and coldness are likely to be felt.
-
The impression is transferred to the model wax to be worked on.
-
This model is processed so that shape, size and position of both eyes are symmetric.
-
The model is placed into a cast and “sclera” (white part of the eye) is formed from white acrylic.
-
Based on the patient’s eye color, iris painting is performed with natural pigments which will not fade in time.
-
The sclera and the iris are put together.
-
The sclera of the prosthetic eye is colored and the vessels fashioned to match the white part of the companion eye.
-
The whole prosthesis is covered with clear acrylic. In addition to a sensation of depth and a more lifelike appearance, this step allows for a healthier fit in the socket.
