Once Was Blind

Russell Turnbull once was blind:

[He] lost most of the vision in his right eye when he had ammonia sprayed into it as he tried to break up a fight on a late night bus journey home.
The attack, which badly burned and scarred his cornea, left him with permanent blurred sight and pain whenever he blinked. 
But now he sees:
his sight has been almost fully restored thanks to a new technique where doctors regrow the outside membrane of his cornea from stem cells taken from his healthy eye.
Chalk up another amazing cure to adult stem cells.
