A couple of years ago adult stem cells saved the eyes of my son. He was losing his vision due to long-term effects of a chemical burn. The stem cells were taken from healthier parts of one eye and transplanted into both eyes. After just a few days (maybe 4), his sight was near normal, better than before the surgery, and after a couple of weeks, his sight was normal. Now a couple of years later you would never guess he had ever been injured.
son=son-in-law, but he’s like a son to me.
