Non-repairable damaged globe

Evisceration

Severely traumatized eye balls are necessarily to be removed.            Sometimes, one find some foreign body inside. It has to be removed as in this case marble was unexpectedly found and thereby removed. Care to be  taken not to leave any uveal tissue as it might be present out side the ruptured and lacerated globe in the orbital contents. 

Enucleation

It is unfortunate to enucleate eye ball but whenever it should be done, has to be done properly to avoid contracted socket at a later date. Usually it is performed in neoplasms. The conjunctiva must be preserved and properly sutured back to avoid contracted socket. If primary orbital implant is to be put one must be sure that the tumour is not malignant.

Exenteration

This is an unfortunate procedure to be carried out in malignancies and there is no chance of saving the globe and sight and if chance is taken it can endanger the patient’s life. Depending upon the extent and the type of malignancy either total or lid sparing extenteration can be performed. This patient had maggots secondary to sebaceous gland carcinoma.

Primary Orbital Implantation

When orbital implantation is performed simultaneously with evisceration or enucleation, it is called as primary orbital implantation. The results of this procedure are excellent but one must look for correct indication. 

Secondary Orbital Implantation

When orbital implantation is performed as a secondary procedure at a later date after previously performing evisceration or enucleation, it is called as secondary orbital implantation. The results of this procedure are not that good as far as movement of the prosthesis is concerned.
