I don’t know much about medical trials but this seems surprisingly low to me, especially given that the study population is presumably predisposed to liking the device (since they opted-in to an experimental study).

Did the implant not work in these cases or were there other quality-of-life issues? I wish university press releases on science were less rah-rah and presented more factual information. I guess that’s what the NEJM article is for.

Can't wait to see what advancements will be made in vision-related healthcare over the next 20 years.

It also means that there is the potential here for night vision.
