Final answer:
The removal of an entire eyeball is called enucleation, not to be confused with exenteration or evisceration, while evacuation is not a term used for this procedure.
Step-by-step explanation:
The removal of an entire eyeball is medically referred to as enucleation. This procedure is distinct from exenteration, which involves removing the entire contents of the eye socket including the eyeball, eyelid, and surrounding tissues, and from evisceration, which involves removing the contents of the eye while leaving the scleral shell and extraocular muscles intact. Evacuation, on the other hand, is a term that is not commonly used in the context of ocular surgery and does not describe the removal of an eyeball.
