Abstract

This paper discuss the feasibility study of implanting an epiretinal prosthesis in humans with bare or no light perception vision from retinitis pigmentosa. Patients were implanted with a Second Sight intraocular epiretinal prosthesis in the eye with worse vision. The implant consisted of an extraocular microelectronic device and an intraocular electrode array, connected by a multiwire cable. At the end of the procedure, it was concluded that all the subjects could see visual perceptions that correlate to electrical stimulus from a chronically implanted retinal prosthesis. Patients used a camera driven stimulus to perform simple tasks.
