Abstract
An intraocular camera for retinal prostheses may include an optical imaging system comprising a set of optical elements for forming an image of the external world on an image sensor array, wherein the optical elements and the image sensor array may be enclosed in an implantable biocompatible housing that may employ haptic elements for stabilization within the eye. The set of optical elements may be designed to have a short focal length and to provide adequate resolution images that can be transformed into a set of stimulation signals applied to a pixellated microstimulator array. Transmission of the signals from the intraocular camera to a microstimulator driver circuit may be accomplished either by a wired or wireless communication device. Power and control signals may be provided to the intraocular camera by a wired or wireless communication device, or optically by means of ambient illumination or an optical beam.
