Macular degeneration, which kills the photoreceptors at the center of the retina, robs nearly a third of Americans older than 75 of their "straight-ahead" vision. With a quick outpatient procedure, this telescope eye implant restores this vision by spreading that light to healthy celts on the retina's perimeter. It takes a few days for the brain to adjust to the implant, but in clinical trials, three quarters of users saw their vision improve from "severe impairment" to "moderate impairment" - they could once again read, watch TV, and recognize faces.
