HI..my husband had a cornea transplant about 2/12 mths ago...he has keratoconus and has had one before..he woke up one day and couldn't see out of his eye..went to the dr. and he told him that's what he needed...but..he hadn't had any problems with the eye at all..dr told him that it had been happening and he just didnt notice it..husband still can't see out of the eye..blurry..when he had the other eye done, he could see right away...any thoughts to whether something else might have been wrong with the eye since husband didnt notice anything..I mean..does the cornea just go bad over night?
