ABSTRACT:
An ocular device that can more safely and effectively perform all functions needed of a retinal prosthesis with electronic components that are placed outside the wall of an eye, are powered wirelessly provided by an external power source, and which provide a patient with a view determined by natural motion of the eye and triggered by natural incident light converging at the retina. In one aspect, the invention is an externally powered, light-activated, sub-retinal prosthesis in which natural light entering the eye conveys visual details to the sub-retinal prosthesis, while wireless radiofrequency transmission provides the power needed to stimulate the retina, which would be insufficient if it were obtained from the intensity of incoming light alone.
