Abstract
A self-sufficient retinal prosthesis powered by intra-ocular photovoltaic cells illuminated only by ambient light is provided. Photovoltaic cells can be disposed at the periphery of the retina or in the anterior chamber of the eye. An adaptive retinal prosthesis is also provided, such that the number of pixels energized in the prosthesis is selected according to the variable available power from ambient light.
