Absolutely excellent.Don't go anywhere else this is the best in the country (and the most expensive!!!)The visx3 laser is superb. All my movements were obviously tracked perfectly.I found it impossible under the enormous stress to look in one place for 30 seconds. My left eye was -7 and I was worried it wouldn't be very good.Now its 20 20.My left eye was -5 now it is absolutetly perfect and I mean absolutely perfect.Both eyes had a degree of astigmatism. Don't think it is painless though!I was in agony for about 2 to 3 hours.Side effects - none except a slight glare around lights at night which should die down over the next few months. I have large pupils - about 7.3mm but I'm fine.I strongly recommend Keith Williams (my surgeon)and their excellent team. My special thank you is to Caroline.
