Photovoltaic restoration of sight in age-related macular degeneration

Presentation Description : We report the first clinical results with photovoltaic sub-retinal prosthesis (PRIMA, Pixium Vision) in patients with advanced dry age-related macular degeneration. Wireless subretinal implant of 2x2mm in size and 30 micrometers in thickness is powered by near-infrared light, which enables relatively simple implantation in the central

Photovoltaic Restoration of Central Vision in Atrophic Age

Purpose: Loss of photoreceptors in atrophic age-related macular degeneration results in severe visual impairment, although some peripheral vision is retained. To restore central vision without compromising the residual peripheral field, we developed a wireless photovoltaic retinal implant (PRIMA; Pixium Vision, Paris, France) in which pixels convert images projected from video
