when my son was 2 yrs old he had a partial cornea transplant. he has had poor eyesight in that eye for as long as he was able to tell me. his pupil is the shape of a cat s but at an angle. he is 15 yrs old now & is getting headaches which he says are from his eye. is there anything that can be done to correct this? NOTE: he had the surgery because something was poked into his eye.
