Clinical trial (2021)
5 subjects with end-stage RP, implanted in right eyes. 90-day visual rehabilitation. All performed significantly better on grating/Tumbling E, direction of motion, square localization, orientation/mobility. 99.9% electrode success rate (1279/1280). 1 AE: electrode array movement + low IOP.
