目的探讨小切口虹膜摘出术（SMILE）治疗近视的临床效果。在这项前瞻性临床研究中，我们评估了224例近视患者的447只眼睛，有和没有散光。我们在SMILE后随访了6个月。术前平均（±标准差，SD）等效球镜为-6.75 ± 1.65屈光度（D），术后6个月为-0.21 ± 0.37 D。我们的数据显示，97.9%的眼睛在预期矫正的±1.0 D范围内，86.1%在预期矫正的±0.5 D范围内。此外，术后6个月，79.8%的患者裸眼远视力（UDVA）为0 logMAR或更低（Snellen等效值为20/20或更高）。此外，48.5%保持不变，41%获得一行矫正远视力（CDVA），7.2%获得两行CDVA，3.3%失去一行CDVA，0.3%失去两行或更多行CDVA。在线性回归分析中，年龄是术后6个月UDVA恶化的唯一预测因素（年龄每增加10岁，logMAR降低0.07; P < 0.05）。没有预测因素显示与术后6个月等效球镜屈光度误差相关。SMILE是一种安全有效的屈光手术。年龄是影响视力结果的唯一预测因素，但其影响在临床上似乎不显著。随着手术技术的改进，预计视力恢复也会更快。
To report our experience with small incision lenticule extraction ("SMILE") for myopia treatment. In this prospective clinical study, we evaluated 447 eyes from 224 patients with myopia, with and without astigmatism. We followed the patients for 6 months after SMILE. The mean (±standard deviation, SD) spherical equivalent was -6.75 ± 1.65 diopters (D) preoperatively and -0.21 ± 0.37 D at 6 months postoperatively. Our data showed that 97.9% of eyes were within ±1.0 D and 86.1% were within ±0.5 D of the intended correction. Furthermore, 79.8% had an uncorrected distance visual acuity (UDVA) of 0 logMAR or less (20/20 or better in the Snellen equivalent) 6 months after surgery. Additionally, 48.5% remained unchanged, 41% gained one line of corrected distance visual acuity (CDVA), 7.2% gained two lines of CDVA, 3.3% lost one line of CDVA, and 0.3% lost two or more lines of CDVA. Age was the only predictor for worsening UDVA at 6 months postoperatively in linear regression analyses (0.07 decrease logMAR per increased 10 years of age; P < 0.05). No predictor showed an association with error in spherical equivalent refraction at 6 months postoperatively. SMILE is an effective and safe refractive surgery. Age was the only predictor that influenced visual outcome, but its effect appeared clinically insignificant. Faster visual recovery is also expected with improved surgical technique.
