AbstractObjective. PRIMA subretinal implants provide prosthetic vision in patients blinded by age-related macular degeneration, with acuity closely matching the sampling limit of the pixel pitch: a single 100 μm pixel per line of a letter corresponds to 20/420 acuity. Decreasing the pixel size in the same flat geometry is difficult due to the constrained electric field, especially considering a 40 μm thick debris layer separating the implant from the target neurons.
