Prima Vision, a company based in Paris, France, is reporting that its PRIMA wireless subretinal implants for people who lost their vision has show a great deal of promise in a pre-clinical trial. The technology is designed specifically for those whose natural photoreceptors no longer function, yet who retain retinal neurons that can be electrically activated. A bunch of the implants are injected into the back of the eye, each around 70-μm in width that represents a single pixel. The implants are basically tiny photovoltaic solar panels that emit electricity in response to light hitting their surface.
