Eye prostheses for partially restoring vision in photoreceptor degenerative retinal disease sufferers comprises a camera converting images into electrical signals

摘要

The prostheses comprises a camera converting images into electrical signals, which are modulated into RF carrier signals for wireless transmission from a coil (16) outside the eye (in e.g. an eyeglass lens) to as second coil (18) implanted behind the iris (48). This is connected to decoding circuitry (20) from where the signals are coupled to the retina (50) by an electrode array (22). An independent claim is also included for the following: The method of partially restoring vision to sufferers from phtotreceptor degenerative retinal conditions.
