Retinal implant

New device delivers highest resolution currently available

Stanford University researchers have designed an implantable retinal prosthesis with five times the resolution of the best devices being tested.

“Our implant provided not only the highest resolution, but it also shaped vision rather than just light sensitivity,” according to Daniel Palanker, PhD, a professor of ophthalmology and senior author of an article published in November 2022 in Nature Communications describing the device.

The device was designed to restore vision loss due to age-related macular degeneration, which damages the retina, causing blurred center vision. After successfully testing the implant in rats, the researchers are now optimizing the device for clinical trials.
