Parts of Eye
In simple, these are the important parts of human eye

Having understood the parts of the Human Eye, we can now look at what part of human eye is donated in case of an Eye Transplant. Basically, Cornea is removed from the donor and donated to the blind person in case of an Eye transplant.

The cornea allows light to enter the eye for Vision. The cornea is the clear front surface of the eye. It lies directly in front of the iris and pupil, and it allows light to enter the eye. One person can donate eyes to two people.

So, the complete eye ball is not removed from the socket. Only the clear surface of the eye is removed and is transplanted.
