Agreed. Luckily, now they're able to grow bone on Nanotubes.

I think you meant the biology news link to the same research

The article states that they have a few dozen pizels today, and are aiming for 50-100 pixels. That's not awesomely revolutionary, considering tests of 16 pixels were being conducted in the late 1990's.

However, other researchers have managed 5000 pixels (70x70) although they don't have hard numbers about how many of those can be seen by patients.

From what I gather, most of these experiments rely on the patient having decent optics to start with; by any large, they're trying to fix detached retinas, not shortsightedness or whatever.
