Phil Durst works on his computer in Homewood, Ala., on Tuesday, Aug. 15, 2023. Durst underwent an experimental procedure that aims to treat severe injuries in one eye with stem cells from the other. “I went from completely blind with debilitating headaches and pondering if I could go another day — like really thinking I can’t do this anymore" to seeing well enough to drive and emerging from dark places literally and figuratively, he says.
