Surgeons at NYU Langone Health in New York City transplanted a complete human eyeball into a 46-year-old Arkansas man — the first time in medical history such a procedure had been carried out. The operation, performed in May 2023 C.E. on Aaron James of Hot Springs, Arkansas, took more than 20 hours and combined a whole-eye transplant with a partial face transplant and a pioneering stem cell infusion into the optic nerve.
At a glance
- Whole-eye transplant: Surgeons at NYU Langone Health transplanted an entire donor eyeball into James, the first confirmed procedure of its kind ever performed.
- Optic nerve stem cells: Donor adult stem cells were injected directly into James’ optic nerve during surgery in an attempt to stimulate repair and possible regeneration of damaged nerve tissue.
- Blood flow to retina: The transplanted eye is being described by doctors as “healthy” — blood is flowing to the retina, a medically significant result even though James has not yet regained vision.
How a workplace accident led to a medical first
James was working as an electrical lineman in 2021 C.E. when his face came into contact with a live wire carrying 7,200 volts. The jolt was catastrophic. He lost his lips, nose, left cheek, chin, front teeth, and parts of his left arm. Surgeons in Texas had to remove his left eyeball because the surrounding tissue was causing severe pain.
What followed was two years of preparation. The team at NYU Langone had asked those Texas surgeons to cut James’ optic nerve as close as possible to where it had connected to the eye — preserving maximum nerve length in anticipation of a future transplant. That foresight made the New York procedure possible.
Earlier in 2023 C.E., James was placed on an organ transplant list. When a compatible donor was identified, the surgical team moved quickly. The donor provided facial tissue, a whole eyeball, and adult stem cells for the procedure.
What surgeons did — and why the stem cells matter
The surgical team, led by Eduardo D. Rodriguez — director of the face transplant program at NYU Langone Health — combined three interventions in one operation. The face transplant restored James’ features. The eyeball transplant placed a functioning donor eye in the left socket. And the stem cell infusion targeted the optic nerve directly.
The optic nerve is the critical link between the eye and the brain. Without it carrying electrical signals, even a structurally healthy transplanted eye cannot produce vision. Stem cell therapy aimed at the optic nerve is a relatively new concept, though doctors in Boston have previously restored partial vision by infusing stem cells from a patient’s own healthy eye into a damaged one. Using donor stem cells on a transplanted optic nerve in this way was entirely new territory.
“The mere fact that we’ve accomplished the first successful whole-eye transplant with a face is a tremendous feat many have long thought was not possible,” Rodriguez said in a statement. “We’ve made one major step forward and have paved the way for the next chapter to restore vision.”
Healthy eye, vision still uncertain
The results so far are genuinely promising — and genuinely partial. Blood is flowing to the retina, the layer of cells at the back of the eye that converts light into electrical signals. Doctors say the eye appears healthy. That is a far better outcome than many expected at this stage.
But James has not regained sight in the transplanted eye, and the surgical team is careful not to overstate what has been achieved. Whether the optic nerve will regenerate enough to carry visual signals to the brain remains an open question. Optic nerve regeneration in humans has never been demonstrated in a transplant context, and the stem cell approach used here is still deeply experimental.
Restoring functional vision through a whole-eye transplant may still be years — or decades — away. The biology of the optic nerve makes it one of the most difficult structures in the human body to repair. What this operation does establish is that a transplanted human eyeball can survive in a new host with blood supply intact, which was itself considered improbable by many in the field.
A door opened for future patients
The wider significance of the James procedure lies in what it demonstrates for the field. Surgeons now know that whole-eye transplantation with simultaneous facial reconstruction is survivable, that a transplanted eye can remain biologically viable, and that stem cell delivery to the optic nerve is at least technically feasible in this context.
For people who have suffered catastrophic eye injuries — through electrical accidents, combat wounds, or industrial trauma — that represents a meaningful shift in what medicine might one day offer. The path from this first procedure to restored sight is long and uncertain. But the door has been opened in a way it never was before.
James himself, by agreeing to be a participant in what was openly described as a highly experimental procedure, contributed directly to that opening. His case will inform the research, the protocols, and the surgical techniques for every attempt that follows.
