Retinal implant invented by Stanford scientist restores limited vision to blind adults with macular degeneration

Summary
A Stanford-invented retinal implant called PRIMA, now manufactured by Science Corp. in Alameda, is restoring limited vision to blind adults with advanced macular degeneration. The tiny chip, inserted into the eye, has enabled patients in Europe to recognize faces, read, paint, and perform daily tasks they couldn't do before. The device works by converting light into electrical signals that stimulate retinal neurons, bypassing damaged photoreceptors. While not restoring full vision, it provides functional sight improvements that significantly enhance quality of life for people who were legally blind.

· 3 pulledA chip the size of a pencil point inserted into the eye has helped a few dozen blind adults in Europe regain some vision — they've been able to paint, to recognize faces and to read to their grandchildren again.
The device, a prosthetic retinal implant, is the first of its kind...
It's not a cure, but it's a significant step forward in restoring functional vision to those who have lost it.
