artificial retinas implanted

 
::
First silicon chip artificial retinas implanted in blind patients, at the University of Illinois at Chicago Medical Center. The Artificial Silicon Retina (ASR) was invented by Alan Chow and his brother Vincent Chow, president and vice president of Optobionics Corporation of Illinois.

It is a silicon microchip about one-tenth of an inch in diameter and one-thousandth of an inch thick-less than the thickness of a human hair. The ASR contains approximately 3,500 microscopic solar cells that convert light into electrical impulses.

The purpose of the chip is to replace damaged photoreceptors, the "light-sensing" cells of the eye, which normally convert light into electrical signals within the retina.
