An Epiretinal Photoacoustic Stimulation Approach for Retinal Stimulation
The feasibility of the proposed epiretinal PAS mechanism was successfully evaluated in an ex vivo porcine retinal explant model using a Pd-Si layer that provides greater PA pressure and faster heat dissipation than previous epiretinal absorptive layers. The epiretinal PAS approach could be a option for less-invasive retinal prosthetic implant technology. The benefits of finer spatial control and a compact system would be enormous.
