A retinal implant could one day be used to restore vision lost through injury or disease, after it gave a brief glimpse of light to a group of patients. The device is the creation of Shawn Kelly from Carnegie Mellon University in Pittsburgh, and the result of a decade's worth of research. It is made up of two tiny cameras attached to a pair of glasses which send images to a computer chip attached to the patient's eye. The chip turns the images into an electrical current sent along a wire to a film inserted behind the retina.
