I would recommend spending that bit extra for warefront with intralase. I have no pain and had 20/20 vision with hours after surgery. The healing time is much better and faster. Optical Express have a great track record with many happy customers. Only regret I have is not having it done sooner. However you must wait for your eyes to settle down and not keep changing before you have this done. However Optical Express do many tests before you book the treatment
