Bionic eye update:
Surgeons have carried out the first operations in Britain using a pioneering "bionic eye" that could in future help to restore blind people’s sight.

Two successful operations to implant the device into the eyes of two blind patients have been conducted at Moorfields Eye Hospital in London.

The device — the first of its kind — incorporates a video camera and transmitter mounted on a pair of glasses. This is linked to an artificial retina, which transmits moving images along the optic nerve to the brain and enables the patient to discriminate rudimentary images of motion, light and dark.
