Surgeons in New York Announce World's First Eye Transplant

Surgeons in New York have performed the first-ever whole-eye transplant in a human, they announced on Thursday, an accomplishment being hailed as a breakthrough even though the patient has not regained sight in the eye.
In the six months since the surgery, performed during a partial face transplant, the grafted eye has shown important signs of health, including well-functioning blood vessels and a promising-looking retina, according to the surgical team at NYU Langone Health.
“The mere fact that we transplanted an eye is a huge step forward, something that for centuries has been thought about, but it's never been performed,” said Dr. Eduardo Rodriguez, who led the team.
Until now, doctors have only been able to transplant the cornea, the clear front layer of the eye, Reuters reported.
The recipient of the eye, Aaron James, is a 46-year-old military veteran from Arkansas who survived a work-related high-voltage electrical accident that destroyed the left side of his face, his nose, his mouth and his left eye.
The transplant surgery took 21 hours.
Initially, doctors were just planning to include the eyeball as part of the face transplant for cosmetic reasons, Rodriguez said during a Zoom interview.
“If some form of vision restoration occurred, it would be wonderful, but... the goal was for us to perform the technical operation,” and have the eyeball survive, Rodriquez added.
Whatever happens going forward will be monitored, he said.
Presently, the transplanted eye is not communicating with the brain through the optic nerve.
To encourage healing of the connection between the donor and recipient optic nerves, surgeons harvested adult stem cells from the donor’s bone marrow and injected them into the optic nerve during the transplant, hoping they would replace damaged cells and protect the nerve.
Transplantation of a viable eye globe opens many new possibilities, Rodriguez said, even if sight is not restored in this case.
Other research teams are developing ways to connect nerve networks in the brain to sightless eyes through insertion of electrodes, for example, to allow vision, he said.
“If we can work with other scientists that are working on other methods of restoring vision or restoring images to the visual cortex, I think we're one step closer,” Rodriguez said.
James, who had retained vision in his right eye, knew he might not regain vision in the transplanted eye.
The doctors “never expected it to work at all, and they told me that from the get-go,” he said.
“I told them, 'even if I can’t see... maybe at least you all can learn something to help the next person.’ That’s how you get started," he said. "Hopefully this opens up a new path.”
James might still regain sight in the transplanted eye, Rodriguez said.
