About this trial
The purpose of this study is to determine the feasibility of producing artificial vision in persons with blindness. Study participants will have wireless electrical stimulators implanted into the cortical vision processing areas of their brains. The ability of the participants to perceive artificial vision in response to electrical stimulation will be assessed.
