How Does the Argus II Work?


The Argus II is intended to be implanted in a single eye, typically the worse-seeing eye. The individual wears glasses equipped with a camera that captures images and converts them into a series of small electrical pulses.

The pulses are transmitted wirelessly to the prosthesis and its array of electrodes on the surface of the retina. These pulses are intended to stimulate the retina’s remaining cells, resulting in the corresponding perception of patterns of light in the brain. The patient then learns to interpret these visual patterns, thereby regaining some visual function.
