LAUSANNE, Switzerland — A blind patient with advanced retinitis pigmentosa became the first recipient of a commercial implant intended to restore some vision, according to a press release.
The patient received the Argus II Retinal Prosthesis System, made by Second Sight, on Oct. 29 in Pisa, Italy, the release said. The device received marketing clearance in Europe this year.
The prosthesis uses a miniature camera in the patient's glasses to capture video images, which are then converted into electric impulses that are transmitted wirelessly to an array of electrodes on the surface of the retina, according to the release. The impulses stimulate the retina's remaining cells, allowing the recipient to perceive and interpret patterns of light, regaining some vision.
The patient is recovering, the release said. Testing and customization will begin shortly, with the patient potentially using the prosthesis at home by the end of November.
