Enucleation is the surgical removal of the eye that leaves the eye muscles and remaining orbital contents intact. This type of ocular surgery is indicated for a number of ocular tumors, severe ocular trauma, and in eyes that are otherwise blind and painful.The reason for enucleation in this case was a growing retinoblastoma. This is a rare malignant tumor of the retina, affecting young children, typically before the age of 5.During the operation, an orbital implant is usually put in to take the place of the eyeball. The implant is made out of silicone or hydroxyapatite (a substance similar to bone). It is attached to the muscles that moved the eye, so it should move the same way as the eye would have. Prosthesis nowadays can be made so good that you can barely tell that it is not a real eye.
