Abstract

PURPOSE The aim of this study is to assess the changes and differences in early postoperative binocular accommodative function following femtosecond laser-assisted in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE). METHODS In this retrospective study, 120 patients (240 eyes) diagnosed with low-to-moderate and high myopia, who underwent either FS-LASIK or SMILE procedures were included. The assessment encompassed measurements of accommodative facility, accommodation time, relaxation time, and accommodation-to-relaxation ratio using a smart flipper. Measurements were taken preoperatively, as well as at 1 day, 1 week, and 1 month postoperatively. Additionally, the visual fatigue scale score was assessed and compared at the 1 month mark post-surgery. Changes in parameters were quantified by calculating the difference between preoperative values and those recorded at each postoperative time point. RESULTS At 1 month post-surgery, both FS-LASIK and SMILE procedures demonstrated potential for recovery or even improvement in accommodative facility, accommodation time, relaxation time, and accommodation-to-relaxation ratio compared to preoperative levels. The FS-LASIK group exhibited a greater magnitude of change in accommodative facility postoperatively compared to the SMILE group. In the low-to-moderate myopia subgroup, the FS-LASIK group exhibited lower changes in accommodation time and visual fatigue scale score at 1 month post-surgery compared to the SMILE group, with all associated p-values <0.05. CONCLUSIONS Early postoperative recovery of accommodation function was slower following SMILE compared to FS-LASIK. Additionally, the severity of visual fatigue at 1 month post-surgery was greater in the SMILE group than in the FS-LASIK group. This difference in visual fatigue levels may be attributed to the delayed recovery observed in postoperative SMILE procedures.

飞秒激光辅助原位角膜磨镶术和小切口皮瓣提取术后早期适应效果评估

本研究的目的是评估飞秒激光辅助原位角膜磨镶术（FS-LASIK）和小切口皮瓣摘除术（SMILE）术后早期双眼适应功能的变化和差异。方法在这项回顾性研究中，纳入了120名被诊断为中低度和高度近视的患者（240只眼），他们都接受了FS-LASIK或SMILE手术。评估包括使用智能翻转器测量适应能力、适应时间、松弛时间和适应松弛比。测量在术前、术后 1 天、1 周和 1 个月进行。此外，术后 1 个月时还对视觉疲劳量表进行了评估和比较。结果术后 1 个月时，FS-LASIK 和 SMILE 两种手术的适应能力、适应时间、松弛时间和适应松弛比与术前相比都有可能恢复甚至改善。与 SMILE 组相比，FS-LASIK 组术后的适应能力变化幅度更大。在中低度近视亚组中，与SMILE组相比，FS-LASIK组术后1个月时的适应时间和视觉疲劳量表评分变化较小，相关的P值均小于0.05。此外，SMILE 组术后 1 个月的视疲劳严重程度高于 FS-LASIK 组。视疲劳程度的这种差异可能是由于在SMILE术后观察到的恢复延迟所致。
