目的比较高度近视和轻中度近视患者小切口晶状体摘除术（SMILE）后的屈光状态和高阶像差。这项前瞻性研究包括165只眼（86例患者）接受SMILE。根据术前等效球镜（SE）将治疗眼分为高度近视组（>-6.0 D，H组）和轻中度近视组（<-6.0 D，M组）。术后1天、10天、1个月和3个月随访。我们获得了以下参数：裸眼视力（UDVA）和矫正远视力（CDVA）、SE、有效性和安全性指数以及HOA。H组术前SE为-7.16 ± 0.93 D，M组为-4.34 ± 0.97 D。术后3个月时，H组和M组的SE分别为-0.20 ± 0.37D和0.01 ± 0.19D（t =-4.11，P<0.05）。发现H组和M组分别有77%和98%的UDVA为20/20，98%和99%的CDVA为20/20，而H组中87%和95%的SE在±0.5 D和±1.0 D内，M组中98%和100%。疗效指数H组为0.98 ± 0.18，M组为1.05 ± 0.10（t =-3.084，p < 0.05）。安全性指数分别为1.06 ± 0.09和1.06 ± 0.09（t = 0.153，p > 0.05）。总HOA、3阶彗差和4阶球面像差显著增加。SMILE是一种安全有效的近视矫正手术。但高度近视患者的目标矫正量应适当调整，以避免欠矫，获得更高的满意度。SMILE诱导HOA增加。ChiTrial注册号：ChiCTR-OON-16009164。Retroperitoneal注册日期：2016年9月6日
To compare the refractive results and higher-order aberrations (HOAs) after small incision lenticule extraction (SMILE) in high myopia and mild to moderate myopia patients. This prospective study included 165 eyes (86 patients) undergoing SMILE. According to the preoperative spherical equivalent (SE), treated eyes were divided into two groups: the high myopia group (more than -6.0 D, group-H) and the mild to moderate group (less than -6.0 D, group-M). Follow-up intervals were at 1 day, 10 days, 1 month and 3 months postoperatively. We obtained the following parameters: uncorrected (UDVA) and corrected distance visual acuity (CDVA), SE, efficacy and safety index, and HOAs. Preoperative SE was -7.16 ± 0.93 D in group-H and -4.34 ± 0.97 D in group-M. At 3 months postoperatively, the SE in group-H and group-M was -0.20 ± 0.37 D and 0.01 ± 0.19 D (t = - 4.11, P<0.05), respectively. It was found that 77% and 98% had an UDVA of 20/20, 98% and 99% had a CDVA of 20/20 in group-H and group-M, respectively, while 87% and 95% had a SE within ±0.5 D and ±1.0 D in group-H, and 98% and 100% in group-M. The efficacy indexes were 0.98 ± 0.18 in group-H and 1.05 ± 0.10 in group-M (t = - 3.084, p < 0.05). The safety indexes were 1.06 ± 0.09 and 1.06 ± 0.09 (t = 0.153, p > 0.05), respectively. There were significant increases in total HOAs, 3rd-order coma, and 4th-order spherical aberrations. SMILE is an effective and safe surgery for correcting myopia. But the target correction amount in high myopia patients should be adjusted to avoid undercorrection and acquired more satisfaction. SMILE induced increases of HOAs.
