I had a valve replacement in 11/06 Aortic and a anuerysum repair in my root. I have had vision problems ( up close) reading and such since then. I have worn glasses for the computer and work for a few years before but now my vision seems to just come and go (blurry) at times of the day?? Talked to my surgeon regarding this he says since I was on the bi-pass for 6.5 hours that that it will take time to heal, that sometimes air pockets get behind your eyes? He told me to also go to the eye doctor and have my eyes checked. Has anybody had trouble with this or heard of this problem. Doing good other wise, still some good and bad days. Hate the ticking of my valve!!!! I have a St Judes valve, and on blood thinner. I am 50 years old!!
