为了评价使用WaveLight® Refractive Suite（Alcon® Laboratories Inc.，USA）。设置.罗斯柴尔德基金会，法国巴黎。 前瞻性干预性病例系列。 我们检查了30例21.3~38.7岁患者的60只近视眼（平均SE − 4.5 D，范围为− 9.3~− 0.75 D）。术前、术后1天（D1）、术后1个月、3个月和6个月测量角膜厚度、角膜曲率、Q因子、角膜像差、视力（VA）、对比敏感度、干眼评估和视觉质量。 术后6个月，角膜曲率变得更平坦，Q因子变得更扁平（从-0.18 ± 0.08到+0.19 ± 0.06）。D1时角膜厚度减小117.9 ± 62.2 µ m，D1和M6之间增大37.87 ± 32.6 µ m。D1时屈光正常，此后保持稳定。术后6个月，VA略有改善，但无显著性（<0.05 log MAR），而对比敏感度保持不变。视力质量不受手术影响，与干眼症状的相关性大于与角膜HOA的相关性（r2 = 0.49; p <0.001 vs. r2 = 0.03; p <0.001）。 使用WaveLight® Refractive Suite进行的中高度近视LASIK手术显示出良好的术后结局，并证明了安全性、可预测性、有效性和稳定性。这可能是由于良好控制的球面像差和使用大的光学区。此外，我们可以假设患者的视力质量更多地取决于激光产生的术后干眼症，而不是诱发的HOA。
To evaluate changes in corneal anatomy and quality of vision following LASIK refractive surgery for mild to high myopia using the WaveLight® Refractive Suite (Alcon® Laboratories Inc., USA). Setting. Rothschild Foundation, Paris, France. Prospective interventional case series. We examined 60 myopic eyes (average SE −4.5 D, from −9.3 to −0.75 D) of 30 patients from 21.3 to 38.7 years old. Pachymetry, keratometry, Q factor, corneal aberrations, visual acuity (VA), contrast sensitivity, dry eye assessment, and quality of vision were measured preoperatively, one day (D1), and 1, 3, and 6 months postoperatively. 6 months postoperatively, keratometry became flatter, and the Q factor became more oblate (from −0.18 ± 0.08 to +0.19 ± 0.06). Pachymetry decreased by 117.9 ± 62.2 µm at D1 and increased by 37.87 ± 32.6 µm between D1 and M6. Refraction was emmetropic at D1 and remained stable thereafter. Six months after surgery, VA was slightly but nonsignificantly improved (<0.05 log MAR), whereas contrast sensitivity remained unchanged. Quality of vision was not affected by surgery and was more related to dry eye symptoms than to corneal HOAs (r2 = 0.49; p < 0.001 vs. r2 = 0.03; p < 0.001). LASIK surgery for moderate to high myopia, performed with the WaveLight® Refractive Suite, showed good postoperative outcomes, with demonstrated safety, predictability, efficiency, and stability. This is probably due to well-controlled spherical aberration and the use of large optical zones. Besides, we can assume that the patients' quality of vision depends more on the postoperative dry eye disease generated by the laser than on the induced HOAs.
