Retinal prosthesis with visible-light filter

摘要: Apparatus is provided, including an external device, a mount, placed in front of eye, and laser which emits toward the eye radiation that outside 380-750 nm. The apparatus additionally includes intraocular device implanted entirely energy receiver, plurality stimulating electrodes, photosensors, driving circuitry coupled to receiver configured drive electrodes apply currents retina response signals from photosensors. photosensors are (a) generally insensitive laser, (b) sensitive visible light. Other applications also described.
