As others have pointed out, the titanium remark is a non-sequitur. The infection was most likely caused by the implant breaking the skin, which is an absolute medical blunder to begin with. For the device to have had any chance of working in the long run, it would have to be completely sealed within the eye socket. In there, it could be recharged using induction and it could receive data through an optical or radio interface that sends signals across the skin. There is not a lot of information about the device or the procedure they used to install it, but the whole thing sounds as if it was poorly conceived.
