Overview
- A multicenter European study of 38 people with geographic atrophy reported that 84% regained the ability to read letters and words using the PRIMA system.
- Clinically meaningful visual acuity gains at 12 months were recorded in 26 of 32 assessed participants, indicating sustained functional improvement.
- The rice-sized subretinal chip contains 378 electrodes and is wirelessly powered by near-infrared images projected from camera-equipped glasses.
- Safety tracking documented 26 serious adverse events in 19 patients, mostly early postoperative issues such as elevated eye pressure, retinal detachment, and subretinal hemorrhage that generally resolved with treatment.
- Researchers report preserved peripheral vision alongside restored central vision and are advancing higher-resolution iterations, extended monitoring, and regulatory filings following the New England Journal of Medicine publication.
