  • 2023: FDA approval


The Prima System aims to elicit functional artificial, or bionic, vision in the form of light perception replacing partially the natural central vision loss. The Prima System is composed of three main elements: Wireless retinal implant, pair of glasses with a camera and digital projector, and a pocket processor. It was approved by the FDA in 2023 for implantation in human patients with atrophic dry age-related macular degeneration (AMD) with the goal of partially restoring their vision.
