I had my first done three months ago and have an appointment for the second, which I am looking forward to. A jolly group of people on the day agreed after our ops that we would rather do that again, than go to the dentist, so you can tell it wasn't too bad! A little uncomfortable, but not painful, and the transformation in vision was amazing. Recovery very rapid. I was about to be told to stop driving, but within two days of the op was cleared to drive again.
Now I have stopped wearing glasses, no need, my optician says, except for reading. That takes some getting used to after a lifetime with specs. So relax, and ask questions if you need to (I didn't - they explained every minor step) and look forward to amazing eyesight afterwards.
