ABSTRACT:
An artificial retina device and a retinal stimulation system and method for stimulating and modulating its function is disclosed. The artificial retina device includes multi-phasic microphotodiode subunits. In persons suffering from blindness due to outer retinal layer damage, a plurality of such devices, when surgically implanted into the subretinal space, may allow useful formed artificial vision to develop. By projecting real or computer controlled visible light images, and computer controlled infrared light images or illumination, simultaneously or in rapid alternation onto the artificial retina device, the nature of induced retinal images may be modulated and improved. The retinal stimulation system may be worn as a headset. Color images may be induced by programming the stimulating pulse durations and frequencies of the stimulation.
