Vision-Restoring Implants That Fit Inside The Eye

This comes from MIT's Technology Review. Apparently, there is much work being done on a coming generation of retinal implants that utilize nano-scale electronic components to dramatically improve vision quality in individuals blinded by degenerative eye disease.

“Smaller materials do have the possibility of giving higher-resolution images,” says Shawn Kelly, a bioengineer at Carnegie Mellon University, who is developing a microscale retinal prosthesis. “Smaller electrodes can get closer to individual nerves, and you can have many more of them.”

A company in Israel and a team at the University of California, San Diego, appear to be leading the pack. See the linked article for details.
