Oxford Surgeons Perform World’s First Robotic Eye Surgery

The procedure was necessary because the patient had a membrane growing on the surface of his retina, which had contracted and pulled it into an uneven shape. The membrane is about 100th of a millimeter thick and needed to be dissected off the retina without damaging it.

"Operating at the back of the eye needs great precision and the challenge has been to get a robot system to do that through a tiny hole in the wall of the eye without causing damage as it moves around," said Prof Robert MacLaren, from Oxford University, who carried out the procedure.

The surgeons used a joystick to control the robot while monitoring its progress through the operating microscope.

"Most robots in the theater are big, with big engineering, whereas this is tiny - everything had to be shrunk down. Normally, when we do this operation by hand, we touch the retina, and there is some hemorrhage. But when we used the robot, the membrane was lifted cleanly away."

"The degeneration in my vision was very scary," Mr Beaver said. "I was fearful I would lose my sight entirely - so for this intervention to take place so effortlessly is a real godsend."
