To evaluate the efficacy, predictability, and safety of laser in situ keratomileusis (LASIK) retreatment in eyes with hyperopia.
Multicenter refractive surgery centers and University Hospital, Germany.
Retrospective case series.
This multicenter study included hyperopic patients with a preoperative difference between cycloplegic and manifest refraction of 1.00 diopter (D) or less who had LASIK retreatment based on manifest refraction. The refractive outcome was analyzed according to standard graphs for reporting the efficacy, predictability, and safety of refractive surgery.
One hundred thirteen eyes of 113 consecutive hyperopic patients were enrolled. Efficacy (P < .001) and safety (P = .004) were statistically significantly improved by retreatment without being negatively influenced by preoperative manifest spherical equivalent (SE), manifest cylinder, or keratometry. In cases still showing a trend toward undercorrection, retreatment resulted in 88 eyes (78.0%) being within ±0.50 D of the attempted correction. The optical zone (OZ) diameter of the retreatment did not correlate with efficacy, predictability, or safety.
Retreatment after hyperopic LASIK resulted in high efficacy, predictability, and safety outcomes. The efficacy and safety of the retreatment were not affected by preoperative manifest SE, manifest cylinder, keratometry, or OZ diameter.
评估远视患者 LASIK 激光原位角膜磨镶术（LASIK）增效手术的疗效、可预测性和安全性。
德国多中心屈光手术中心和大学医院。
回顾性病例系列。
本多中心研究纳入了术前睫状肌麻痹验光与主觉验光相差 1.00 屈光度（D）或更小的远视患者，并根据主觉验光行 LASIK 增效手术。根据屈光手术疗效、可预测性和安全性的标准图表对屈光结果进行分析。
113 例连续远视患者的 113 只眼被纳入研究。增效手术后的疗效（P<.001）和安全性（P=.004）均有统计学意义的改善，且未受到术前主觉等效球镜（SE）、主觉柱镜或角膜曲率的负面影响。在仍有欠矫趋势的情况下，88 只眼（78.0%）经增效手术后的屈光度在目标矫正值的±0.50 D 范围内。增效手术的光区（OZ）直径与疗效、可预测性或安全性均无相关性。
远视 LASIK 增效手术后可获得较高的疗效、可预测性和安全性。增效手术的疗效和安全性不受术前主觉 SE、主觉柱镜、角膜曲率或 OZ 直径的影响。
