Abstract: :
Purpose: To evaluate the efficacy, stability, predictability, and safety of CustomVue LASIK using IntraLase and Visx S4 for patients with myopia or myopic astigmatism. Methods: Retrospective analysis of 144 eyes of 77 patients with myopia or myopic astigmatism who underwent CustomVue LASIK using IntraLase and Visx S4 was conducted. Refraction, mean spherical equivalent (SE), uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BSCVA), and mean higher wavefront analysis were determined pre–operatively and at 3 months post–operatively. Results: Mean preoperative SE was –4.15 +/–1.78 D (range –8.38 to +0.13 D). Three month postoperative mean SE was –0.07 +/– 0.30 D (range –1.13 to + 1.13 D). At 3 months postoperative, 45%, 86%, and 98% of eyes had 20/15, 20/20, and 20/40 or better vision respectively. 97% of eyes were within 1.0 D of emmetropia at 3 months postoperatively. At 3 months postoperatively compared to preoperatively, all eyes either gained/loss 1 or had no change in Snellen Line (BSCVA). Stable mean RMS values were obtained at postoperative month 1 and 3 compared to preoperatively (0.31, 0.31 vs 0.28). Conclusions: IntraLase and Visx S4 is comparable in efficacy, stability, predictability, and safety to the Hansatome microkeratome and Visx S4 used in CustomVue LASIK for patients with myopia and myopic astigmatism.
