In eye donation, the part of the donor`s eye that is utilized is the cornea. The cornea is the clear, dome-shaped outermost layer of the eye that covers the front portion of the eye. It is responsible for refracting light and plays a crucial role in focusing the light onto the retina, which is located at the back of the eye.

During eye donation, the cornea is carefully removed from the donor`s eye and transplanted to a recipient who has a damaged or diseased cornea. Corneal transplantation, also known as corneal grafting or keratoplasty, is a common procedure to restore vision and treat various corneal conditions such as corneal infections, injuries, dystrophies, or scarring.

It`s important to note that only the cornea is used in eye donation, not other parts of the eye such as the iris, lens, or retina. The cornea can be donated after death, and it can greatly improve the vision and quality of life for those in need of a corneal transplant.
