Bionic digital eyes for blind people

I read an article in a magazine about digital eyes that actually worked to cure blindness once implanted, though current version was at a low resolution so it's not 100% perfect.  Does anyone know what magazine this came from or a website with more info on these? 

It's pretty awesome - there is research into man-machine interfacing, bionic senses (sight, sound), bionic limbs. Soon we will all be Robocop!
