The Argus™ II Retinal Prosthesis System

The Argus II Retinal Prosthesis System ("Argus II") is designed to bypass damaged photoreceptors in certain blind patients. A miniature video camera housed in the patient’s glasses captures a scene. The video is sent to a small patient-worn computer (i.e., the video processing unit – VPU) where it is processed and transformed into instructions that are sent back to the glasses via a cable. These instructions are transmitted wirelessly to a receiver in the implant.
