First Nonstudy Argus II Retinal Prosthesis Implanted

February 2014

The Argus II retinal prosthesis is 3 x 5 mm and surgically implanted onto the surface of the retina, where it acts to replace damaged photoreceptor cells in retinitis pigmentosa and other hereditary retinal diseases. The current generation device has 60 electrodes which stimulate the retina with electrical signals generated from a video camera mounted on a pair of eyeglasses.
