To compare refractive outcomes, visual acuities, and satisfaction of patients between those treated with laser-assisted in situ keratomileusis (LASIK) using a Hansatome microkeratome (HM) and femto-assisted laser (FAL).
This was a retrospective analysis of 1,366 eyes in 687 patients who underwent LASIK with an HM (n=1,137) and an FAL (n=229) at the two centers of Hashmanis Hospital, Karachi, Pakistan. Refractive outcomes, including sphere, cylinder, and spherical equivalent in diopters (D), and visual acuities were assessed both preoperatively and at 1 month follow-up. Patient satisfaction was gauged by contacting the patient at the time of chart review.
The postoperative median sphere, cylinder, and spherical equivalent values for those treated with FAL were 0.3±0.7 (-5.5-1.8), -0.5±0.6 (-5.0-1.0), and 0.0±0.7 (-6.0-1.6), respectively. For the HM arm, they were 0.0±1.28 (-10.8-6.8), -0.5±0.5 (-4.5-1.5), and -0.3±1.3 (-11.6-6.8), respectively. All preoperative values were statistically insignificant between the groups, while postoperative values were significant with -values <0.001. Predictability and efficacy index was higher for the FAL (92.1%, 1.00) than the HM group (82.2%, 0.84). Similarly, patient satisfaction was slightly higher for those treated with FAL (93.3%) than HM (91.4%).
Our large retrospective analysis of eyes that have undergone LASIK using HM and FAL shows superior refractive outcomes in the latter, with special regard to procedural efficacy and predictability.
比较使用汉斯刀微型角膜刀（HM）和飞秒激光辅助（FAL）进行准分子原位角膜磨镶术（LASIK）治疗的患者的屈光结果、视力和满意度。
这是一项对巴基斯坦卡拉奇哈什马尼医院两个中心687例接受LASIK手术的患者的1366只眼睛进行的回顾性分析。其中，使用HM的患者有1137例，使用FAL的患者有229例。术前和术后1个月随访时评估屈光结果，包括球镜度、柱镜度和等效球镜度（屈光度，D）以及视力。通过在查阅病历期间联系患者来衡量患者满意度。
FAL治疗组术后球镜度、柱镜度和等效球镜度的中位数分别为0.3±0.7（-5.5至1.8）、-0.5±0.6（-5.0至1.0）和0.0±0.7（-6.0至1.6）。HM治疗组相应的值分别为0.0±1.28（-10.8至6.8）、-0.5±0.5（-4.5至1.5）和-0.3±1.3（-11.6至6.8）。两组术前所有值在统计学上无显著差异，而术后值差异显著，P值<0.001。FAL组的可预测性和有效性指数（92.1%，1.00）高于HM组（82.2%，0.84）。同样，FAL治疗患者的满意度（93.3%）略高于HM治疗患者（91.4%）。
我们对使用HM和FAL进行LASIK手术的眼睛进行的大型回顾性分析表明，后者在屈光结果方面更优，特别是在手术有效性和可预测性方面。
