From Engadget:

It works by processing images from the camera and wirelessly transmitting them to a receiver implanted in the eye, which in turn sends signals to a series of electrodes that stimulate the retina, sending the information to the brain, all of which happens in real time. While it won’t restore full sight, the researchers say patients should be able to detect light and distinguish objects from one another.

While not a complete cure, this combination of a camera and neural connections to the retina itself, has been shown to help macular degeneration and retinal pigmentosis.

The technology is exciting and another example of how electronic devices can transmit signals to the brain when the body no longer can.  Unfortunately the devices is expected to cost about $30,000 and that might leave a lot of people out.  Hopefully as the device enters widespread production the cost will come down.
