I had lasik 3 days ago and still have hazy vision - anyone treated this problem?

Not unusual. You should call your surgeon, but it is not unusual to have haziness after lasik. It took my own lasik about a week to really clear up.
LASIK. Your description could be normal due to eye surface dryness or irritation. It typically takes a few weeks for the vision to stabilize after lasik. If the vision does not improve or you have associated pain, you need to see your eye surgeon.
