First Bionic Eyes Successfully Implanted

TimesOnline- 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.
The operations were conducted as part of an international clinical trial of the technology, known as the Argus II retinal implant, which has already proved successful in restoring rudimentary vision to patients who have become blind because of common conditions such as age-related macular degeneration or retinitis pigmentosa. American researchers are hoping to develop a camera the size of a pea that could be implanted within the eyeball, replacing natural tissue with artificial technology.
Surgeons hope that the implant could be available to NHS patients within three to five years.
