Final answer:
Enucleation is the surgical procedure for the removal of the entire eyeball. Exenteration is the removal of all the contents of the eye socket, while keratoplasty is corneal transplantation and evisceration involves removing the eye's contents but leaving the scleral shell.
Step-by-step explanation:
The removal of the entire eyeball is referred to as enucleation. This is a surgical procedure that consists of removing the eye while leaving the eye muscles and remaining orbital contents in place.
Exenteration on the other hand, is the removal of the entire contents of the eye socket including the eyeball and surrounding tissues often due to malignancy. Keratoplasty is a procedure that involves the transplantation of corneal tissue and evisceration involves the removal of the contents of the eye but leaving the scleral shell and extraocular muscles intact.
