Bionic Vision Lab @bionicvisionlab.org · Mar 22 Similar to van Steveninck et al. (2021), we trained a deep net to predict the optimal stimulus to produce a desired percept. 2 important changes: - ✅psychophysically validated phosphene model - ❌no *de*coder (which could unlearn any deficiencies of the *en*coder)

As a proof of concept, we show how percept shape *might be* improved for the implant settings of three existing Argus II users. Results are expected to be highly patient-specific, mainly depending on: - intraocular implant location - behaviorally reported phosphene distortions
