A wireless subretinal implant (PRIMA) restored functional central vision in a clinical study of patients with geographic atrophy, enabling reading of short words and numbers after years of irreversible vision loss. Investigators led by Dr. Jose‑Alain Sahel reported an average gain of 25 letters on standard eye charts and meaningful improvements in 26 of 32 participants at one year, with 27 using the system at home. The device replaces lost photoreceptors with photovoltaic pixels that stimulate residual retinal neurons—an approach that could broaden device‑based options for atrophic macular degeneration.
