Why can't we transplant a whole eye?
The eye is connected to the brain by the Optic Nerve, which consists of over 1 million tiny nerve fibers. Once cut, these fibers cannot be reconnected.
However, the front window of the eye—the Cornea—can be transplanted successfully. This is what restores vision for millions of people worldwide.
Fig 1: The Cornea (front) is replaceable. The Optic Nerve (back) acts like a cable to the brain and cannot be reconnected yet.
