<p>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. In another aspect, the present invention provides means for controlling and communicating, from outside a patient's body, a transformation algorithm and parameters of the algorithm by which an optical pattern incident on the prothesis is converted to a pattern of electrical stimulation of the retina that conveys useful information to the patient and influences visual function.</p> |
