Abstract
PURPOSE: To evaluate functional vision and quality-of-life outcomes after bilateral wavefront-guided laser in situ keratomileusis (LASIK). SETTING: Byers Eye Institute, Stanford University School of Medicine, Palo Alto, California, USA. DESIGN: Prospective case series. METHODS: Visual acuity, refractive error, and aberrometric measurements were obtained preoperatively and 1, 6, and 12 months after bilateral wavefront-guided LASIK. The Refractive Status and Vision Profile questionnaire scores were completed at each timepoint and compared with baseline scores. RESULTS: The study comprised 84 eyes of 42 patients (aged 24 to 47 years). At 1 year, 76 eyes (90.5%) had an uncorrected distance visual acuity of 20/20 or better and 88.1% of patients were satisfied with their vision without correction. Total refractive status and vision profile scores improved significantly from a mean of 30.9 points at baseline to 20.7 points 1 year postoperatively (P < .001). The visual function, perceptions, and problems with corrective lenses subscales statistically significantly improved from preoperatively to postoperatively (all P < .001). In contrast, the driving (P = .286) and visual symptoms subscales (P = .199) did not show significant changes from baseline to 1 year. CONCLUSION: Wavefront-guided LASIK not only afforded clinically measurable improvements in vision but also significant improvements in subjective functional vision and vision-related quality of life 1 year after surgery.
