Factors affecting two-point discrimination in Argus II patients [PDF]
Frontiers in Neuroscience, 2022 Two of the main obstacles to the development of epiretinal prosthesis technology are electrodes that require current amplitudes above safety limits to reliably elicit percepts, and a failure to consistently elicit pattern vision.

A Patient-Specific Computational Framework for the Argus II Implant [PDF]
IEEE Open Journal of Engineering in Medicine and Biology, 2020 Goal: Retinal prosthesis performance is limited by the variability of elicited phosphenes. The stimulating electrode's position with respect to retinal ganglion cells (RGCs) affects both perceptual threshold and phosphene shape.
