This study assessed the clinical safety and efficacy of elliptical thin-flap LASIK with a low-pulse energy femtosecond laser in 3 thickness subgroups (85, 90, and 100 μm). A total of 80 patients who underwent bilateral LASIK surgery at Taiwan between April and September 2019 were retrospectively enrolled. Elliptical corneal flaps with wide temporal hinges and inverted-angled side cuts were created. Target flap thickness was calculated on the basis of residual stromal bed thickness and percent tissue altered. Before flap creation, an optical coherence tomography image for visualization of the precut flap position was obtained with the built-in camera. At postoperative month 1, the overall mean logMAR uncorrected distance visual acuity (UDVA) was - 0.04 ± 0.07 (20/18 Snellen), with 96% of eyes achieving UDVA of 20/20 or better. Postoperative mean manifest spherical equivalent was - 0.37 ± 0.42 D at 1 month. The visual and refractive outcomes in each of the 3 subgroups were similar. The achieved flap thicknesses were found to be highly predictable and consistent in the respective thickness subgroups. Optical coherence tomography-guided thin-flap LASIK performed with the low-pulse energy femtosecond laser was found to be safe with no intraoperative or postoperative complications.
本研究评估了低能量飞秒激光在 3 个厚度亚组（85、90 和 100μm）下的椭圆薄瓣 LASIK 的临床安全性和疗效。2019 年 4 月至 9 月期间，共有 80 名在台湾接受双侧 LASIK 手术的患者被回顾性纳入研究。采用宽颞侧铰链和反向角度侧切口制作椭圆形角膜瓣。目标瓣厚度根据剩余基质床厚度和组织改变百分比计算。在制作瓣之前，使用内置相机获得用于可视化预切割瓣位置的光学相干断层扫描图像。术后 1 个月，总体平均 logMAR 未矫正距离视力（UDVA）为-0.04±0.07（20/18 Snellen），96%的眼睛达到 20/20 或更好的 UDVA。术后 1 个月平均等效球镜为-0.37±0.42 D。3 个亚组的视觉和屈光结果相似。在各自的厚度亚组中，发现所获得的瓣厚度具有高度可预测性和一致性。使用低能量飞秒激光进行的 OCT 引导的薄瓣 LASIK 是安全的，没有术中或术后并发症。
