摘要

A retina implant, comprises a surface and a plurality of pixel elements disposed on the surface for receiving and converting incoming light energy into electric energy. At least one amplifier is provided in the implant, and a plurality of stimulation electrodes supplied via the at least one amplifier as a function of signals received by the pixel elements. At least one light-sensitive reference element is coupled with the at least one amplifier for controlling amplification thereof as a function of light energy impinging on the at least one reference element.
