Are Scanning Excimer Lasers With Tracking Better Than VISX S-2 Smooth-Scan Laser?
No, peer-reviewed studies involving large numbers of patients published in leading journals have shown no difference in visual results when comparing the VISX S-2 Smooth-Scan Laser with scanning lasers with tracking.

Is the Bausch & Lomb Hansatome Microkeratome Used For LASIK Really Safer Than Other Microkeratomes?
Yes, the Hansatome Microkeratome has been shown to be safer than other microkeratomes, such as the automated corneal shaper, in studies performed at the University of Washington and other institutions. The rate of flap complications with the Hansatome Microkeratome at the University of Washington is less than 1 in 500--1,000 cases. The complication rate with other microkeratomes can be as high as 5%.

Can LASIK Be Used to Reduce Astigmatism and Myopia After Corneal Transplantation?
Yes, LASIK is very effective in treating astigmatism and myopia that remains after suture removal following corneal transplantation.

Are There Some Circumstances Where PRK May Be a Better Choice than LASIK for the Correction of Nearsightedness or Farsightedness?
Yes, our published studies and those of other investigators have demonstrated that in patients with less than 4-5 diopters of myopia, the chance of losing two lines of best-corrected visual acuity is less with PRK than LASIK. The University of Washington Refractive Surgery Center provides critical information to the patient and allows them to make the choice between PRK and LASIK based on their own level of correction.
