There are unfortunately situations when an eye should be removed from the eye socket. In these cases, an implant is usually placed into the eye socket after the removal of the eye to compensate for the loss of orbital volume. After the eye socket has healed, a molding is then made to create an ocular prosthetic that fits snugly into the eye socket and resembles the fellow eye.  The ocular prosthetics are usually made from acrylic, but may be referred to as a glass eye. Polycarbonate optical lenses should then be worn at all times to protect the fellow eye. The health of the eye socket must be monitored by Dr Zatezalo, as anophthalmic sockets (a socket without an eye) have the propensity to have oncologic problems. The ocular prosthetic is usually cleaned every 6 months to a year, and replaced approximately every 5 years.
