Who is that lady who regained her sight through a computer eye?

They implanted a camara into her eye socket, which conect to the back of her brain, you know the part that recieves the electro signals from your eye. She couldn't see perfectly, but the camara enabled her to se flashy outlines of objects around her. I believe I saw it on the science channel. I wnat to know her name and/or the technology used on her.
