Implanting the Argus II is a well -established surgery, typically taking only a few hours. The procedure is performed by an experienced retinal surgeon, with Second Sight technicians available for your support. Once implanted, the Argus II implant sits in and around the back of the eye and is not visible to others. It is accompanied by external accessories that include glasses with a built in camera and a small portable processing unit that together capture and process video signals to be sent to the implant. Once the Argus II has been implanted, you will return to the clinic after approximately 4 weeks of healing to have your Argus II activated and programmed to your specific needs.
