Question

Why can't a whole eye be transplanted ?

Answer 1

Answer 2

Answer 3

No. Only the cornea may be transplanted. A corneal transplant is the surgical procedure which replaces a disc-shaped segment of a defective cornea with a similarly shaped piece of a healthy donor cornea. The new cornea is placed into the area where the damaged tissue was removed and then stitched into place.
