US EditionElectronic eye implant allows blind patients to regain sight
The PRIMA implant restored reading vision in 84% of advanced dry AMD patients, enabling them to read an average of five lines on a vision chart, trial data shows.
- TUESDAY, Oct. 21, 2025, the PRIMA System restored reading vision for 84% of trial participants, with results published in the New England Journal of Medicine.
- With geographic atrophy affecting 5 million people worldwide, existing drugs only slow vision loss and Science Corporation developed the implant to address this unmet need in advanced dry age-related macular degeneration.
- Worn augmented-reality glasses with video camera project near-infrared light while a pocket/waistband computer with AI processes images from the 2mm x 2mm microchip, 30 micrometres thickness, producing about 400 spots of vision.
- Patients in trial reported regained reading, puzzle, and text recognition abilities, with 26 serious adverse events in 19 participants; 70-year-old Sheila Irvine said it was "out of this world" to read again.
