A retina implant including a chip adapted to be implanted into the interior of eye in subretinal contact with the retina. The chip has a plurality of pixel elements on a side thereof facing the lens for receiving an image projected into the retina and a plurality of electrodes for stimulating retina cells. The implants further includes a receiver coil for inductively coupling thereinto electromagnetic energy. The receiver coil coupled to a means for converting an alternating voltage induced into the receiver coil in a direct voltage suited for supplying the chip. The receiver coil is configured as a component separate from the chip, and for being positioned on the eye ball outside the sclera. The chip is connected to the receiver coil via a connecting lead which, in the implanted condition interconnects the interior and the exterior of the eye ball.
