Artificial eye
Ocular Prosthesis is a prosthesis of the eye which is commonly known as an artificial eye. There are two types of ocular prosthesis –
1. Readymade Prosthesis
A readymade prosthesis is one that is made according to standard sizes and colors in factories. These are sold in bulk so that a trial and error can be done to find satisfactory results.
The patient is fitted with the prosthesis closest in size and color to the normal eye. But it becomes nearly impossible to find a stock eye which surprisingly matches in all parameters with other eye.
2. Custom made Prosthesis:
Custom prosthesis are made after taking the impression of the affected eye and, the size, shape and centre are made according to the natural eye.
The colors are also matched and painted according to the patient’s Seeing Eye. When a custom made eye is made, the size, shape, lid contours, center of eye, size if iris, size of pupil, colour of iris, colour of sclera (white part of eye) etc. are matched according to the other eye.
A readymade prosthesis is used for short period of time and needs to be removed every night whereas a custom ocular prosthesis can be worn continuously for longer periods of time.
