Abstract:Objective. High-resolution retinal prosthetics offer partial sight restoration to patients blinded by retinal degenerative diseases through electrical stimulation of remaining neurons. Decreasing pixel size enables increasing prosthetic visual acuity, as demonstrated in animal models of retinal degeneration. However, scaling down the size of planar pixels is limited by the reduced penetration depth of the electric field in tissue. We investigated 3-dimensional structures on top of photovoltaic arrays for enhan… Show more
