n.
a surgical operation in which an organ, tumour, or cyst is completely removed. In ophthalmology it is an operation in which the eyeball is removed but the other structures in the socket (e.g. eye muscles) are left in place. Commonly a plastic ball is temporarily buried in the socket to give a better cosmetic result prior to fitting an artificial eye.
