Abstract:
ABSTRACT PURPOSE: To verify whether there is any difference in visual outcome, including higher order aberrations, after performing laser in situ keratomileusis (LASEK) with conventional ablation and wavefront-guided ablation in myopic eyes of the same patient. METHODS: This was a prospective randomized study of 20 myopic eyes (10 patients) who had LASIK using the Nidek NAVEX excimer laser system. Wavefront-guided customized ablation was used in the first eye of the patient (study group) and the other eye of the same patient was operated with conventional ablation (control group). Mean refractive error was similar between left and right eyes of the same patient. Preoperative examination included higher order aberration by Nidek OPDScan. Uncorrected and best spectacle-corrected visual acuity and higher order aberrations were recorded postoperatively. RESULTS: Preoperative and postoperative best spectacle-corrected visual acuity was better than 20/40 (100%) after LASEK in both the conventional ablation and wavefront-guided customized ablation groups. Postoperative refraction was within ±0.50 D of emmetropia: 90% in the conventional group and 100% in the wavefront-guided group. No statistically significant difference in postoperative higher order aberrations was found between groups. CONCLUSION: Postoperative visual outcome with both conventional LASIK and wavefrontguided customized ablation was not significantly different. Higher order aberrations did not significantly increase postoperatively in either group. [J Refract Surg 2003;19(suppl):S217-S220]
