I had the LASIK operation at Accuvision on 20th November 2002 and am now 1 week post-op. The results are superb and still might improve slowly. My prescription was short sight with astigmatism, Right SPH -8 CYL -1.5 AXIS 155, Left SPH -7.5 CYL -1.5 AXIS 15, very large pupils and average corneal thickness. Ultralase said they could do the op with a reasonably good chance of success, but failed to tell me I would be left with a dangerously thin cornea, and still didn't tell me when I asked them directly (after going to Accuvision). My first appointment at Accuvision was double booked, but fortunately I forgave them and went along, thankfully as I found out all about corneal thickness and large pupils. The Wavefront technology they use (incidentally also used in Canada, New Zealand and Australia) goes a long way to solving those problems. I did quite a lot of research into the subject and am glad I chose Accuvision as I have been confident in their abilities since the first consultation. It is expensive, but with an odd prescription, it is worth every penny towards the chance of a good result. Thanks to all at Accuvision, especially, Darius, Vik and Mr. Ayliffe. To those considering the op, check with the clinics when you have the consultation how much of your cornea they will leave behind (the Residual Stroma Thickness is the important part). If the answer is less than 250 microns, start worrying. This is the 'safe' lower limit, but that might not even be 'safe'. The more the better. Don't be surprised if a clinic won't tell you or just give you the total corneal thickness including flap - don't trust them. Accuvision have left me with 270 microns, so I'm pleased with that. Please e-mail me if you would like to know anymore about my experience.
