retinal implant device 3456

Looking at a new view for retinal implants

A German study has successfully implantedretina-replacement electrode arrays in a number of blind patients, allowing them to distinguish letters, words, and objects. The German team joins Australian, European, and Americanuniversity teams and a number of privateprojects in the quest to replace the eye, though they all seem to be going about it in slightly different ways.

This German microelectrode array is quite large and dense — many arrays I’ve heard of have been as small as 10×10 or less, but this 38×40 grid may produce a decent image. It’s still black and white and takes a lot of time to get used to, but hell, it’s better than nothing.
