To assess vision-related, quality-of-life outcomes 5 years after laser in situ keratomileusis (LASIK) and determine factors predictive of patient satisfaction.
Optical Express, Glasgow, Scotland.
Retrospective case series.
Data from patients who had attended a clinical examination 5 years after LASIK were analyzed. All treatments were performed using the Visx Star S4 IR excimer laser. Patient-reported satisfaction, the effect of eyesight on various activities, visual phenomena, and ocular discomfort were evaluated 5 years postoperatively. Multivariate regression analysis was performed to determine factors affecting patient satisfaction.
The study comprised 2530 patients (4937 eyes) who had LASIK. The mean age at the time of surgery was 42.4 years ± 12.5 (SD), and the preoperative manifest spherical equivalent ranged from -11.0 diopters (D) to +4.88 D. Five years postoperatively, 79.3% of eyes were within ±0.50 D of emmetropia and 77.7% of eyes achieved monocular uncorrected distance visual acuity (UDVA) and 90.6% of eyes achieved binocular UDVA of 20/20 or better. Of the patients, 91.0% said they were satisfied with their vision and 94.9% did not wear distance correction. Less than 2.0% of patients noticed visual phenomena, even with spectacle correction. Major predictors of patient satisfaction 5 years postoperatively were postoperative binocular UDVA (37.6% variance explained by regression model), visual phenomena (relative contribution of 15.0%), preoperative and postoperative sphere and their interactions (11.6%), and eyesight-related difficulties with various activities such as night driving, outdoor activities, and reading (10.2%).
Patient-reported quality-of-life and satisfaction rates remained high 5 years after LASIK. Uncorrected vision was the strongest predictor of satisfaction.

回顾性病例系列。
分析了 LASIK 术后 5 年接受临床检查的患者的数据。所有治疗均使用 Visx Star S4 IR 准分子激光进行。术后 5 年评估患者报告的满意度、视力对各种活动的影响、视觉现象和眼部不适。进行多变量回归分析以确定影响患者满意度的因素。
该研究包括 2530 名（4937 只眼）接受 LASIK 的患者。手术时的平均年龄为 42.4 ± 12.5 岁，术前等效球镜度数范围从-11.0 屈光度（D）到+4.88 D。术后 5 年，79.3%的眼在±0.50 D 以内达到正视，77.7%的眼达到单眼未矫正远视力（UDVA）和 90.6%的眼达到双眼 20/20 或更好的 UDVA。91.0%的患者对自己的视力感到满意，94.9%的患者不戴远距矫正镜。即使进行了眼镜矫正，也只有不到 2.0%的患者注意到视觉现象。术后双眼 UDVA 是术后 5 年患者满意度的主要预测因素（回归模型解释的方差为 37.6%），视觉现象（相对贡献 15.0%），术前和术后球镜及其相互作用（11.6%），以及夜间驾驶、户外活动和阅读等各种活动的视力相关困难（10.2%）。
LASIK 术后 5 年，患者报告的生活质量和满意度仍保持较高水平。未矫正视力是满意度的最强预测因素。
