目的：评价LASIK手术的安全性、有效性和长期稳定性，该手术采用了一种新型平台，包括飞秒和准分子激光以及多种网络诊断。在使用新型屈光平台的近视LASIK手术的连续病例中（FS 200飞秒和EX 500准分子激光），190只眼（来自109名不同患者）在术前和术后评价了以下参数：屈光不正，最佳矫正远视力，裸眼远视力，地形图（基于Placido-disc）和断层扫描（基于Scheimpflug图像）、波前分析、瞳孔测量和对比敏感度。随访至少12个月。结果：术前至术后平均屈光不正的变化为-5.29 +/-2.39屈光度（D）（范围-8.0至-0.50 D）至3个月访视时-0.27 +/- 0.09 D，6个月访视时-0.27 +/- 0.10 D，1年访视时-0.39 +/- 0.08 D。术前至术后屈光散光的变化为-1.07 +/- 0.91 D（范围-4.25至0 D）至3个月时的-0.14 +/- 0.04 D，6个月时为-0.15 +/- 0.04，1年访视时为-0.16 +/- 0.04。术后散光在0.5 D以内的患眼比例范围为95.6%-99%。结论：FS 200飞秒激光和EX 500准分子激光治疗近视LASIK临床效果显著，安全性高，长期稳定性好。
Purpose: The evaluation of the safety, efficacy, and long-term stability of LASIK procedures utilizing novel platform comprising a femtosecond and excimer laser and multiple networked diagnostics.Setting: Private clinical ophthalmology practice.Patients and methods: In consecutive cases of myopic LASIK procedure with a novel refractive platform (FS200 Femtosecond and EX500 Excimer Laser), 190 eyes (from 109 different patients) were evaluated pre- and postoperatively for the following parameters: refractive error, best corrected distance visual acuity, uncorrected distance visual acuity, topography (Placido-disc based) and tomography (Scheimpflug-image based), wavefront analysis, pupillometry, and contrast sensitivity. Follow-up visits were conducted for at least 12 months.Results: The change from pre-to postoperative mean refractive error was from -5.29 +/- 2.39 diopters (D) (range -8.0 to -0.50 D) to -0.27 +/- 0.09 D at the 3-month visit, -0.27 +/- 0.10 D at the 6-month visit, and -0.39 +/- 0.08 D at the 1-year visit. The change from pre-to postoperative refractive astigmatism was -1.07 +/- 0.91 D (range -4.25 to 0 D) to -0.14 +/- 0.04 D at 3 months, -0.15 +/- 0.04 at 6 months, and -0.16 +/- 0.04 at the 1-year visit. The proportion of the eyes with postoperative astigmatism within 0.5 D ranged between 95.6% and 99%. The proportion of eyes achieving uncorrected distance visual acuity of 1.0 (decimal) was 93.0%.Conclusion: The myopic LASIK clinical results with the FS200 Femtosecond Laser and EX500 Excimer Laser showed outstanding efficacy, great safety, and long-term stability.
