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

Result
Your answer: —  Â·  Correct: A
Explanation

The part of the eye transplanted in eye donation is the cornea (option 1). Corneal transplantation (keratoplasty) replaces a diseased or damaged cornea with healthy donor corneal tissue to restore vision; globally millions with corneal blindness can be helped by corneal grafts, as noted in donor/recipient discussions and the potential to cure about 4.5 million corneal blind people through corneal transplantation [1]. Corneas are explicitly listed among common transplantable tissues and are routinely used in surgical restoration of sight [2]. Anatomically, the cornea is the transparent front membrane of the eye responsible for most refraction, making its replacement directly effective at restoring clarity of vision [3].
