Pam Belluck, The New York Times:

The arti­fi­cial retina is a sheet of elec­trodes implanted in the eye. The patient is also given glasses with an attached cam­era and a portable video proces­sor. This sys­tem, called Argus II, allows visual sig­nals to bypass the dam­aged por­tion of the retina and be trans­mit­ted to the brain.

Argus II is made by Second Sight Medical Products.
