Update following my comments on 10th January. I went along to Accuvision who have the new Wavefront technology and large pupils were confirmed, even though I had 2 separate measurements at my local opticians saving they were smaller than average! Turns out that if I had had the standard LASIK then I would have been very likely to suffer significant night vision problems. My thanks to Mr Panjit for discouraging surgery - despite the initial disappointment he did me a huge favour! I'm booked in to have surgery at Accuvision on 28th February. highly recommend MaxiVision if your eyes are 'normal', Accuvision if you wan the very latest technology - diagnostics and treatment (but at a cost). good luck.
