Researchers from the University of Southern California and the Doheny Eye Institute’s Doheny Retina Institute will be presenting data on the first six patients implanted with an intraocular retinal prosthesis-more popularly referred to as an artificial retina-developed and manufactured in partnership with Second Sight Medical Products, Inc., of Sylmar, Calif.
According to Mark Humayun, professor of ophthalmology at the Keck School of Medicine and the lead investigator on the project, all six of the previously blind patients have been able to detect light, identify objects in their environment, and even perceive motion after implantation with the epiretinal device.
