To report 12-month visual and refractive outcomes following topography-guided femtosecond laser-assisted laser in situ keratomileusis (LASIK) for myopia and compound myopic astigmatism correction.
This prospective, single-center observational study was conducted in an outpatient clinical practice at the Stanford University Byers Eye Institute in Palo Alto, California. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, 5% and 25% contrast sensitivity CDVA, and manifest refraction following topography-guided femtosecond laser-assisted LASIK were assessed. Refractive measurements were used to perform a vector analysis.
Sixty eyes of 30 patients (mean age: 32.8 ± 7.0 years; range: 23 to 52 years) undergoing topography-guided LASIK for the correction of myopia and compound myopic astigmatism were analyzed. Mean postoperative UDVA was -0.09 ± 0.10 logarithm of the minimum angle of resolution (logMAR) at 12 months. Mean preoperative CDVA was -0.09 ± 0.09 and -0.13 ± 0.08 logMAR at postoperative 12 months. At 12 months, 26.9% of eyes had gained one or more lines of postoperative UDVA compared to baseline CDVA. Mean pre-operative 5% contrast sensitivity CDVA was 0.68 ± 0.07 and 0.64 ± 0.12 logMAR at 12 months ( = .014) following LASIK.
Topography-guided LASIK for myopia and myopic astigmatism correction provided excellent visual and refractive outcomes that were predictable, precise, and stable up to 12 months postoperatively. .
报告远视和复合远视散光矫正的地形图引导飞秒激光辅助 LASIK 术后 12 个月的视力和屈光结果。
这是一项在加利福尼亚州帕洛阿尔托斯坦福大学拜尔斯眼科研究所的门诊临床实践中进行的前瞻性、单中心观察性研究。评估了地形图引导飞秒激光辅助 LASIK 术后未矫正（UDVA）和矫正（CDVA）远距视力、5%和 25%对比度敏感 CDVA 和明视屈光度。使用屈光测量值进行矢量分析。
对 30 例（平均年龄：32.8 ± 7.0 岁；范围：23 至 52 岁）接受地形图引导 LASIK 治疗远视和复合远视散光的 60 只眼进行了分析。术后 12 个月的平均 UDVA 为-0.09 ± 0.10 对数最小角分辨率（logMAR）。术后 12 个月的平均术前 CDVA 为-0.09 ± 0.09 和-0.13 ± 0.08 logMAR。术后 12 个月，与基线 CDVA 相比，26.9%的眼获得了 1 行或更多行的术后 UDVA。术前 5%对比度敏感 CDVA 为 0.68 ± 0.07 和 0.64 ± 0.12 logMAR，术后 12 个月（ =.014）LASIK。
针对远视和远视散光矫正的地形图引导 LASIK 提供了出色的视觉和屈光结果，这些结果在术后 12 个月内可预测、精确且稳定。
