Hello my name is kasey. My 71 year old grandfather is blind. His left eye is said to be "bruised" and he cant see anything out of it. Not even shadows. His right eye has scare tissue that other doctors have tried to remove but couldn't. He can see shadows with his right eye. I was curious if he could get an eye transplant for his condition at his age, and would it be affective? He has been blind for 10+ years. Thank You.
