Bionic Vision Australia’s Bionic Eye Gives New Sight to People Blinded by Retinitis Pigmentosa

Via Medgadget

Bionic Vision Australia, a collaboration between of researchers working on a bionic eye, has announced that its prototype implant has completed a two year trial in patients with advanced retinitis pigmentosa. Three patients with profound vision loss received 24-channel suprachoroidal electrode implants that caused no noticeable serious side effects. Moreover, though this was not formally part of the study, the patients were able to see more light and able to distinguish shapes that were invisible to them prior to implantation. The newly gained vision allowed them to improve how they navigated around objects and how well they were able to spot items on a tabletop.

The next step is to try out the latest 44-channel device in a clinical trial slated for next year and then move on to a 98-channel system that is currently in development.

This study is critically important to the continuation of our research efforts and the results exceeded all our expectations,” Professor Mark Hargreaves, Chair of the BVA board, said in a statement. “We have demonstrated clearly that our suprachoroidal implants are safe to insert surgically and cause no adverse events once in place. Significantly, we have also been able to observe that our device prototype was able to evoke meaningful visual perception in patients with profound visual loss.”

Here’s one of the study participants using the bionic eye:
