Nicki,

if it's any consolation, after my epi lasek I couldn't drive for over a week so don't worry too much. I spent the time going for walks, resting or going shopping on public transport! I found that gradually my sight improved. I didn't drive til day 8 but it probably wasn't all that brilliant then. I think it was towards the end of week 2 before i felt confident that I could see where I was going. Stick with it, but do contact whichever clinic you went to for advice meanwhile
