This is an eye enucleation after death, which is the removal of the eyeball that leaves the eye muscles and remaining orbital contents intact. This is done for the purpose of donation, the most common is the cornea, which can be harvested up to twelve hours after death, but ideally within six hours. Eye banks are the institutions responsible for collecting (harvesting) and processing donor corneas, and for distributing them to trained corneal graft surgeons. Cornea harvesting is the surgical removal from a deceased person of either the whole eye (enucleation) or the cornea (in situ corneal excision) for different medical uses in order to improve visual acuity, to reconstruct and to improve the appearance of patients with corneal scars that have given a whitish or opaque hue to the cornea.
