Researchers at MIT and the Massachusetts Eye and Ear Infirmary are striving to
develop an eye implant that could restore vision to patients suffering from retinal
disease, including macular degeneration, an age-related condition that is the
leading cause of blindness. As currently designed, the retinal implant will have
two silicon microchips. One will provide solar power and process an image of the
patient's surroundings taken by a tiny camera mounted on glasses worn by the patient.
The other will decode picture information and send electric pulses to the retina's
ganglion cells, which forward visual signals to the brain.
