The Phosphenes[0] patients sense will depend on what is left of the retina. People using earlier systems reported some interpolation happened. Maybe that is true of this device too.
[0] - that is the name for the image the brain manifests in response to signals received by the visual cortex. Most of us experience them when we close our eyes and rub them, or maybe just see stuff that is unreal.

> Resolution is limited by the size of pixels on the chip. Currently, the pixels are 100 microns wide, with 378 pixels on each chip.
> the PRIMA device provides only black-and-white vision

Very very cool. I have this condition - I got it randomly ("idiopathic" as opposed to age-related) when I was 22. At the time it wreaked havoc on my mental health.
