Terho added, "Right after that, if my eye hit the light, then I was able to see flashes, some activity which I hadn't had."
And, "Then day after day when we started working with it, practising, then I started seeing better and better all the time."

After their success with these patients, the team headed by Dr. Terho is now working on an improved version of their e-chip.
