Surgeons announced the world's first transplant of an entire human eye

the gist

On 9 November 2023, surgeons at NYU Langone Health announced the first whole-eye transplant in a living person. The recipient, a military veteran who had been badly injured in a work accident, received the eye together with part of a donor's face. The challenge is that the optic nerve, which carries signals from the eye to the brain, cannot yet be reliably reconnected, so the surgeons could not expect sight to return. The team showed that the transplanted eye could survive: it had a blood supply and a healthy retina. Before this, only the cornea, the clear front of the eye, could be transplanted, and that restores sight only when the rest of the eye works.

so what

The operation is a proof that a whole eye can be kept alive in a new body. If scientists can find a way to regrow or reconnect the optic nerve, it could eventually restore sight to people who are blind from injury.

fun fact

Corneal transplants are among the most common and successful transplants worldwide.
