I am coming up to 12 months post AVR surgery (second surgery) and have had issues with my vision since. I have days where I struggle with double/triple vision, that my usual glasses do not help with. I am unable to focus clearly, particularly at close range but also for far distance. It seems to be an intermittent issue, happening 3-4 days of the week, and I thought that it would settle as time has passed since the surgery. I recall having a similar issue after my first surgery, but it only lasted a few weeks, unlike this time. Last week, I decided to see the optometrist, to have my vision checked, and he gave my eyes a clean bill of health with my prescription unchanged. He believes that it is a neurological issue as a result of bypass. I haven't found much about it so I'm curious whether others have this as an ongoing issue and if anyone knows more about this. And is there something that I can be doing to correct this? The optometrist didn't believe so. I spend a lot of time in front of a screen and also stitching, which most of the time now, I just can't do, as it just makes me too tired to try to focus correctly. I have tried some magnifiers on my glasses but they aren't helping. Very frustrating! I have my 12 month check with the cardiologist in a couple of weeks' time. I'd love to hear from others who have had this issue and how that all panned out...
