Second-generation artificial retina allows woman to see light

Artificial Retina Video  CNN (12/11, Smith) reported that retinitis pigmentosa patient Barbara Campbell of New York “is one of only 14 people in the” US “participating in an FDA-approved study of” a second-generation “artificial retina” with 60 electrodes. This past July, “Campbell underwent surgery to implant the microchip into her eye” and now “wears a pair of sunglasses outfitted with a small camera. As she scans and focuses the camera on an object in her environment…a wireless device transmits that image to the artificial retina inside her eye,” providing her with a “rudimentary level of vision” that allows her to see light. Scientists are now developing devices with many more electrodes to provide “more detailed vision.”
