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.
