I had Lasik surgery for short sight at the Shaftesbury Avenue clinic at the end of November 2002 and can't recommend it (the surgery) highly enough as have had perfect vision since then. The only problem I have had is slight dryness but this has now cleared up - and to be honest, it was nothing compared to how dry my eyes used to get whilst wearing contact lenses in an air-conditioned office every day! The op itself was painless and very quick, and the surgical team and carer were brilliant.
The only comment I would make about The Norwich Eye Clinic (where I had my consultation and am having my follow-up appointments) is that I have never been seen on time at any of my appointments, prior to or after the surgery. Every time I have been in I've had to wait between 20 minutes to half an hour past the time the appointment was booked for. I have spoken to other people and they have had the same problem. It might seem petty, but definitely detracts from the overall good service that they offer.
Re. the surgery though, anyone who is thinking about it, go for it!
