| ［摘要］ 目的 比较飞秒激光小切口角膜基质内透镜取出术（SMILE）和波前像差引导的准分子激光原位角膜磨镶术（WG-FS-LASIK）治疗低度无散光近视患者术后的早期视觉质量。方法 选择2022年3月至6月在广西壮族自治区人民医院视光中心行SMILE治疗的患者15例（30眼，SMILE组），行WG-FS-LASIK治疗的患者15例（30眼，WG-FS-LASIK组）。所有患者术前无散光且最佳矫正视力所需最低球镜度数均≤-3.00 D。于术前和术后1 d、1周、1个月测量视力、全眼像差（慧差、三叶草像差和球差）、客观散射指数（OSI）、调制传递函数截止频率（MTFcut-off）、斯特列尔比（SR）、可预测对比度视力（PVA）（包括PVA 100%、PVA 20%、PVA 9%）。比较两组观察指标测量结果。结果 两组术后等效球镜、视力情况均较术前显著改善（P<0.05），但两组各时间点比较差异无统计学意义（P>0.05）。两组术后OSI、SR、PVA 9%均较术前显著改善（P<0.05）。WG-FS-LASIK组在术后1 d、1周、1个月的OSI水平均显著低于SMILE组（P<0.05）。在术后1个月，WG-FS-LASIK组PVA 9%显著高于SMILE组（P<0.05）。SMILE组和WG-FS-LASIK组术后慧差均呈先上升后下降的趋势，但WG-FS-LASIK组变化幅度更小，在术后1 d、1周、1个月，WG-FS-LASIK组慧差小于SMILE组，差异有统计学意义（P<0.05）。结论 SMILE和WG-FS-LASIK均能提高低度无散光近视患者术后早期视觉质量，但WG-FS-LASIK早期视力恢复更好，且夜间视觉质量改善更优。 |

| ［Abstract］ Objective To compare the early postoperative visual quality between femtosecond laser small incision lenticule extraction(SMILE) and wavefront aberration guided laser in situ keratomileusis(WG-FS-LASIK) in patients with low myopia without astigmatism. Methods Fifteen patients(30 eyes, SMILE group) undergoing SMILE treatment and 15 patients(30 eyes, WG-FS-LASIK group) undergoing WG-FS-LASIK treatment in the Optometry Center of the People′s Hospital of Guangxi Zhuang Autonomous Region from March 2022 to June 2022 were selected. All the patients had no astigmatism before surgery and their best corrected visual acuities requiring for the minimum spherical lens power were less than or equal to -3.00 D. Visual acuity, total aberrations(coma, trefoil and spherical aberration), objective scatter index(OSI), modulation transfer function cut-off frequency(MTFcut-off), Streeler ratio(SR), and predictable visual acuity(PVA)(including PVA 100%, PVA 20% and PVA 9%) were measured before surgery, and 1 day, 1 week, and 1 month after surgery. The measurement results of the observation indicators were compared between the two groups. Results The equivalent spherical lens and visual acuities were significantly improved in the two groups after surgery compared with those before surgery(P<0.05), but there was no significant difference at each time point between the two groups(P>0.05). The OSI, SR and PVA 9% were improved in both groups after surgery compared with those before surgery(P<0.05). The OSI levels in the WG-FS-LASIK group were significantly decreased 1 day, 1 week and 1 month after surgery compared with those in the SMILE group(P<0.05). One month after surgery, PVA 9% in the WG-FS-LASIK group was significantly higher than that in the SMILE group(P<0.05). The postoperative coma differences in the SMILE group and the WG-FS-LASIK group showed a trend of increasing first and then decreasing, but the changing range of the WG-FS-LASIK group was smaller. The postoperative coma differences in the WG-FS-LASIK group were less than those in the SMILE group 1 day, 1 week and 1 month after surgery, and the differences were statistically significant(P<0.05). Conclusion Both SMILE and WG-FS-LASIK can improve early postoperative visual quality in patients with low myopia without astigmatism, but the patients undergoing WG-FS-LASIK treatment have better early visual recovery and better nighttime visual quality improvement. |
