Abstract

Purpose: To compare the clinical outcomes of myopiacorrected with corneal-wavefront-guided (CWG) laser in situ keratomileusis (LASIK) with AMARIS 1050S (SCHWIND eye-tech-solutions GmbH & Co. KG) and corneal-topography-guided (CTG) LASIK with WaveLight EX500 (Alcon Laboratories, Fort Worth, TX).

Methods: In this prospective, pseudo-randomized expanded cohort study, a total of 266 patients were subjected to binocular LASIK surgery, either with WaveLight EX500 (WaveLight group) or Amaris 1050S (AMARIS group) platforms. Data related to right eyes were selected for analysis. Corneal higher-order aberration (HOA) was selected as the primary endpoint; while visual acuity and refraction were the secondary endpoints. All the endpoints were assessed at 3 months postoperatively.

Results: There were 134 eyes in the AMARIS group and 132 eyes in the WaveLight group. After 3 months of postoperative follow-up, spherical and coma aberrations were significantly lower (P < 0.05) in the WaveLight group (spherical aberration: - 0.104 ± 0.199 µm; coma aberration: - 0.117 ± 0.202 µm) in comparison with the AMARIS group (spherical aberrations: 0.254 ± 0.146 µm; coma aberrations: 0.316 ± 0.297 µm). In the AMARIS group, 96.3% of the eyes achieved an uncorrected distance visual acuity (UDVA) of 20/20 while in the WaveLight group, 96.2% of the eyes achieved an UDVA of 20/20. Furthermore, the mean postoperative manifest refraction spherical equivalent (MRSE) was - 0.02 ± 0.28 in the AMARIS group and - 0.05 ± 0.21 in the WaveLight group (P = 0.34).

Conclusions: Both WaveLight EX500 and Amaris 1050S LASIK showed excellent refractive and visual outcomes. In addition, the WaveLight group showed minimal spherical and coma aberrations when compared to the AMARIS group.

处女眼角膜波前和地形图引导激光原位角膜磨镶术平台的临床效果比较：扩大队列研究。

目的：比较采用AMARIS 1050S (SCHWIND eye-tech-solutions GmbH & Co. KG)角膜波前引导（CWG）激光原位角膜磨镶术（LASIK）和WaveLight EX500 (Alcon Laboratories, Fort Worth, TX)角膜地形图引导（CTG）LASIK手术矫正近视的临床疗效：在这项前瞻性假随机扩大队列研究中，共有 266 名患者接受了双眼 LASIK 手术，分别使用 WaveLight EX500（WaveLight 组）或 Amaris 1050S（AMARIS 组）平台。选择与右眼相关的数据进行分析。角膜高阶像差（HOA）被选为主要终点，视力和屈光度为次要终点。所有终点均在术后3个月进行评估：结果：AMARIS组有134只眼睛，WaveLight组有132只眼睛。术后随访 3 个月后，球差和彗差明显降低（P 结论：AMARIS 组和 WaveLight 组的球差和彗差均明显降低：WaveLight EX500 和 Amaris 1050S LASIK 均显示出良好的屈光和视觉效果。此外，与 AMARIS 组相比，WaveLight 组的球差和彗差最小。
