Demonstration video: Second Sight’s Argus II Retinal Prosthesis System

In Second Sight’s Argus II Retinal Prosthesis System, a miniature video camera in the eyeglasses captures a scene. The video is processed by a small computer and transformed into instructions which are sent back to the glasses. These instructions are then transmitted wirelessly to the implant on the eye. The implant consists of a receiver and an array of electrodes. Instructions are received and corresponding signals sent to the array, which emits small pulses of electricity. These pulses stimulate the retina’s remaining healthy cells and are transmitted down the optic nerve, conveying visual information to the brain, which perceives patterns of light. Patients learn to interpret these visual patterns.
