To quote the researcher:

"Still in Phase II clinical trials, Pollack cautions it is still too early
to determine what percentage of patients might experience improvement in
vision and what resolution capability these patients might eventually have.
"Although we hope that all patients receiving the chip will experience some
improvement in visual function, we can't say for sure how these patients
will respond to this new treatment since this is still an experimental
trial. If this study and future studies show safety and efficacy of the chip
and it's approved by the FDA, it could be as soon as three to five years
that this technology would be available to others."
