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? 

can my eyes get dead pixels? Could you imagine though, people being born to then have their natural eyes replaces with new eyes so their vision will be better? Kinda creepy if you ask me.
