Question 1

subretinal implant vs epirential implant

Answer 1

Retinal implants are designed for patients who are blind because of degenerative diseases that affect the photoreceptors, resulting in progressive vision loss. Even when the visual loss is very advanced, many cells in the retina remain intact.
Therefor the researchers came up with a subretinal implant, which exploits the remaining photoreceptors
vs
and a epiretinal implant, which bypasses the photoreceptor cells and directly stimulates the ganglion neurons on the retina.
