In the eye donation, which part of the eye is transplanted from the donor?

A

Cornea

B

Lens

C

Retina

D

The whole eye

Correct Answer: Option A

Explanation

1. Eye donation involves the donation of eye tissues after death for transplantation. 2. The most commonly transplanted part of the eye is the Cornea. 3. The Cornea is the transparent outer layer at the front of the eye that covers the iris, pupil, and anterior chamber. Corneal transplantation (keratoplasty) can restore vision in individuals with corneal blindness caused by disease or injury. 4. The Lens is located inside the eye and is involved in focusing light; it is replaced during cataract surgery but not typically transplanted from a donor in the context of eye donation for corneal blindness. 5. The Retina is the light-sensitive tissue at the back of the eye; retinal transplants are highly experimental and not standard practice. 6. Usually, the whole eye is enucleated (removed) from the donor, but only the cornea (and sometimes the sclera) is used for transplantation.
