New human trials are underway for a retinal implant that promises to restore vision to people suffering from eye disease.

The implant, called the Artificial Silicon Retina (ASR), contains about 5,000 microscopic solar cells that convert light into electrical impulses.

A silicon microchip two millimeters in diameter and one-thousandth of an inch thick, the implant is intended to replace damaged "light-sensing" cells of the eye called photoreceptors.

These cells normally convert light into electrical signals within the retina. They are lost in people with retinal diseases such as retinitis pigmentosa.

The ASR was invented by Alan Chow of Rush University Medical Center in Chicago.
