👁 PRIMA chip restores central vision in AMD

The PRIMA implant targets geographic atrophy, a late-stage dry form of age-related macular degeneration affecting over 5 million people worldwide. It replaces dead photoreceptors in the central retina with a 2×2 mm chip containing 378 photovoltaic pixels.

The chip converts infrared light projected from special glasses into electrical impulses that stimulate surviving retinal neurons. This bypasses damaged photoreceptors and sends visual signals to the brain, preserving peripheral vision while restoring central sight.

PRIMA does not cure or regenerate cells but acts as an electronic prosthesis. It recently received CE marking, allowing Science Corp to market the system in Europe.
