Eye transplant is an operation to remove all or part of a damaged eyeand replace it with healthy donor tissue. Eye transplant is often referred to as other eye. It can be used to improve sight, relieve pain and treat severe infection or damage.
The eye is a complex organ connected to your brain by the optic nerve. The optic nerve sends visual signals from the eye to the brain, where they are interpreted as images. The optic nerve is relatively small, varying in length between 1.3 and 2.2 inches, and at its widest point, inside your cranial cavity, it is still less than one-fifth of an inch wide. Yet the optic nerve is made up of more than one million tiny nerve fibers. Once these nerve fibers are cut, they cannot be reconnected. That is why it's impossible to transplant a whole eye. Only one part of the eye called cornea can be transplanted, which is the transplantation of clear front part of the eye.
