Tiny Fractal-Shaped Eye Implants Could Mimic Neurons, Allowing Blind Patients to See

Retinal implants can let blind people see, but to be truly effective, they should be adapted to the human eye’s unique structure, according to one researcher. Tiny clusters of material that self-assemble into fractals could help with this, strengthening the connections between an implant and a patient’s healthy neurons.
Some vision disorders, like macular degeneration, damage the eyes’ rods and cones but leave the neurons intact. Implants work by communicating with those neurons, sending visual information to the brain to be processed. But camera chips and eyes do not work the same way, and there are insufficient connections between the neurons and the implanted photodiode light receptors.
