Surgeons have used a robot to operate inside the eye and restore sight - in a world first.
A team at Oxford's John Radcliffe Hospital used the device, controlled via a joystick, to remove a membrane one hundredth of a millimetre thick.
Patient Bill Beaver, 70, a curate in Oxford, said it was "a fairytale".
Surgeons hope the procedure will pave the way for more complex eye surgery than is currently possible with the human hand.
The BBC had exclusive access to the procedure.
