As reported at Science Blog, ophthalmologists have implanted Artificial Silicon Retina microchips
in the eyes of five patients to treat vision loss caused by retinitis
pigmentosa. The implant is a 2mm chip that contains about 5,000
microscopic solar cells that convert light into electrical impulses.
Already some patients have experienced improvements such as not bumping
into objects around the house, and being able to read the time on a
clock.
