I am trying to make a decision about Lasik, and the 2 doctors I have spoken with in Burlington VT (Juli Larson and Geoff Tabin) both seem qualified and dedicated. A key difference seems to be that one uses the S3 and the other the S2. Obviously I want to be treated with state-of-the -art equipment, but I don't really know how critical the differences are in these 2 machines. Is the tracking that important? Do either require dilation before the procedure? Does anyone have another basis for deciding between these 2 particular Drs?

Thanks.
