Electronic implant allows the blind to see - health - 03 November 2010 - New Scientist

Electronic implant allows the blind to see : "Eberthart Zrenner and colleagues at the University of T�bingen in Germany have developed a microchip carrying 1500 photosensitive diodes that slides into the retina where the photoreceptors would normally be. The diodes respond to light, and when connected to an outside power source through a wire into the eye, can stimulate the nearby nerves that normally pass signals to the brain, mimicking healthy photoreceptors.

The team reports that their first three volunteers could all locate bright objects. One could recognise normal objects and read large words."
