A tiny glass telescope of the size of a pea has been successfully implanted in the eyes of people with severely damaged retinas, helping them to read and watch television. The new device by VisionCare Ophthalmic Technologies is for people with an irreversible, advanced form of macular degeneration in which a blind spot develops in the central vision of both eyes. The device, which has received unanimous recommendation from the FDA advisory panel, may receive FDA approval by the end of the year.
