“Three people have received an innovative treatment designed to rejuvenate vision cells. In a presentation at the annual meeting of the American Academy of Ophthalmology, researchers from Life Biosciences reported that the treatment appears safe, and two of the recipients show early signs of improved vision.

The study is among the first approved by the U.S. Food and Drug Administration using a novel strategy of reprogramming cells to restore their normal function—essentially rejuvenating them. The scientists used a modified version of a reprogramming strategy that earned a Nobel Prize in 2012 for turning mature, adult cells back to an embryonic-like state from which they could become any of the cells in the body—including healthy new versions of diseased or older cells. In that work, Japanese scientist Shinya Yamanaka used four genes to trigger the cellular time warp.”
