Over 12 million people across the globe are blind due to damaged corneas or disease. One way to restore vision is through a transplant from a deceased human donor, but they’re few and far between as only 1 in 70 patients receive one. According to a recent NBC News article, the solution could be pigskin. A team of researchers successfully restored sight in 14 blind people by implanting corneas made from a collagen protein found in pigskin.
