PURPOSE To evaluate the outcomes of resident-performed femtosecond laser-assisted in situ keratomileusis (FS-LASIK). METHODS Records of 138 eyes of 69 patients treated by residents for myopia or myopic astigmatism between March 2018 and June 2020 were reviewed. All preoperative visits, procedures, and postoperative visits were supervised by attending physicians. Follow-up examinations were performed 1 day and 1 month postoperatively. Complications and enhancements were noted. Outcome measures included postoperative uncorrected distance visual acuity (UDVA), refractive accuracy, and complications. RESULTS Eighteen residents performed FS-LASIK on a median of 8 eyes (interquartile range: 1.75). Fifty-nine patients (118 eyes) returned for a 1-month postoperative examination. UDVA was 20/40 or better in 117 eyes (99%) and 20/20 or better in 108 eyes (92%). The mean preoperative spherical equivalent (SE) refractive error was -4.01 ± 1.82 diopters (D) in 138 eyes, decreasing to -0.12 ± 0.35 D at 1 month after surgery in the 102 eyes that were refracted. The SE was ±1.00 D in 100 eyes (98%) and ±0.50 D in 94 eyes (93%). The CDVA change was within one line in 100% of eyes. Intraoperative complications occurred in 5 eyes (3.62%), enhancements were performed in 3 eyes (2.17%), and postoperative complications developed in 3 eyes (2.17%). CONCLUSIONS Resident-performed FS-LASIK is relatively safe and effective in comparison to published U.S. Food and Drug Administration premarket approval studies. Early resident experience performing LASIK can improve the training of ophthalmic surgeons while simultaneously increasing patient access to laser vision correction.

近视和近视散光的住院医师执行 FS-LASIK 的结果。

目的 评估住院医师飞秒激光辅助原位角膜磨镶术 (FS-LASIK) 的结果。方法回顾2018年3月至2020年6月住院治疗近视或近视散光患者69例138眼记录。所有术前就诊、手术和术后就诊均由主治医师监督。术后1天和1个月进行随访检查。注意到了并发症和增强。结果指标包括术后未矫正远视力（UDVA）、屈光准确度和并发症。结果 18 名住院医师对 8 只眼的中位数进行了 FS-LASIK（四分位距：1.75）。59 名患者（118 只眼）返回进行了 1 个月的术后检查。117 只眼 (99%) 的 UDVA 为 20/40 或更高，108 只眼 (92%) 的 UDVA 为 20/20 或更高。138 只眼的平均术前等效球面镜 (SE) 屈光度数为 -4.01 ± 1.82 屈光度 (D)，术后 1 个月的 102 眼屈光度数降至 -0.12 ± 0.35 D。100 只眼 (98%) 的 SE 为 ±1.00 D，94 只眼 (93%) 的 SE 为 ±0.50 D。100% 的眼睛的 CDVA 变化在一条线内。术中并发症5眼（3.62%），强化3眼（2.17%），术后并发症3眼（2.17%）。结论 与美国食品和药物管理局公布的上市前批准研究相比，住院医师实施的 FS-LASIK 相对安全和有效。早期住院医师执行 LASIK 的经验可以改善眼外科医生的培训，同时增加患者获得激光视力矫正的机会。[J 屈光手术。2021;37(8):545-551.]。
