Hi,
I too have had laser eye surgery, and have been doing well for 13 years. After surgery I got blurry vision but not all the time. It seemed more often then not though. I have found when I have a bad Water day and am dehydrated my blurry vision gets worse. I drive for a living and the long hours takes a toll on the eyes being blurry as well. So maybe lack of hydration and sitting to long, looking at the puter or reading may affect the vision. I am 4 months out and still am having trouble with getting all my water in, but was like that before the surgery...it has always been a struggle.
Hope this might help...take a look at your hydration levels....and I also put tear gel into my eyes, especially at night before bed when oxygen to the eye is more limited...this has helped me.
