目的比较小切口晶状体摘除(SMILE)和飞秒激光辅助准分子激光原位角膜磨镶术(FS-LASIK)治疗近视及近视散光的远期疗效。在这项回顾性研究中，我们共招募了101名患者(101只眼)，他们在3年前接受了SILE或FS-LASIK手术。测量参数包括裸眼远视力(UDVA)、矫正远视力(CDVA)、显性屈光度和角膜波前像差。两组患者的特征没有发现显著差异。随访3年，屈光度大于或等于20/20者分别为90%和85%(p=0.540)，疗效指数分别为1.05±0.19 和61.01±0.21(p=0.352)。安全指数分别为1.19±0.17 和1.15±0.20(p=0.307)。SILY和FS-LASK术后，分别有80%和65%的眼在尝试的球镜等效校正度范围内(P=0.164)。向量分析显示两组散光矫正无显著差异(p>；0.05)。手术引起的球差在FS-LASIK组高于SMILE组(p<；0.001)。长期随访分析表明，对于近视和散光矫正，SMILE和FS-LASIK都是安全且同样有效的。
To compare long-term clinical outcomes following small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) for myopia and myopic astigmatism correction. In this retrospective study, we enrolled a total of 101 patients (101 eyes) who underwent SMILE or FS-LASIK 3 years prior. Measured parameters included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction and corneal wavefront aberrations. No significant differences in patient characteristics were found between the two groups. At the 3-year follow-up, UDVA was better than or equal to 20/20 in 90% and 85% (p=0.540) of the eyes; the efficacy indexes were 1.05±0.19 and 1.01±0.21 in the SMILE and FS-LASIK groups, respectively (p=0.352). Safety indexes were 1.19±0.17 and 1.15±0.20 in the SMILE and FS-LASIK groups, respectively (p=0.307). Eighty per cent and 65% of eyes were within ±0.50 D of the attempted spherical equivalent correction after SMILE and FS-LASIK, respectively (p=0.164). Vector analysis revealed no significant differences in astigmatic correction between the two groups (p>0.05). Surgically induced spherical aberration was higher in the FS-LASIK group than in the SMILE group (p<0.001). Long-term follow-up analysis suggested that both SMILE and FS-LASIK were safe and equally effective for myopic and astigmatic correction.
