Background:

Retinal degenerative diseases cause blindness by damaging retinal neurons.
Current high-resolution retinal prosthetics partially restore vision via electrical stimulation.
Scaling down planar pixel size is limited by electric field penetration depth.

Conclusions:

Electroplated 3D structures significantly improve stimulation efficiency and spatial resolution in retinal implants.
Honeycomb and pillar designs offer distinct advantages for different retinal conditions and patient needs.
3D structure fabrication is compatible with existing processes, paving the way for advanced visual prosthetics.
