A groundbreaking retinal implant, PRIMA, is restoring central vision in patients with geographic atrophy (GA), an advanced form of macular degeneration that blinds roughly 1 million Americans. Unlike drugs that slow progression, this wireless neurostimulation system captures real-world images, projects them onto a subretinal chip, and electrically stimulates surviving retinal cells to mimic natural sight. Are we nearing a paradigm shift in how we treat vision loss?
