I had a cervical syrgery,fusing discs 5,6,7 with a plate.After the surgery which lasted 5 hours,I did not see very well.My vision is not blurred,but there is something like light which makes me see things not clear as I should.It's been nearly 4 weeks now.I'm being a little better,but still can't see properly.I saw 2 doctors who said that sometimes this happens after long operations,and it should be better by time.I wanted to know if this happened with some one else,and if it is really temporarily or is it permanent.
