To evaluate the visual outcomes after femtosecond laser-assisted laser in situ keratomileusis (LASIK) surgery to correct primary compound hyperopic astigmatism with high cylinder using a fast repetition rate excimer laser platform with optimized aspheric profiles and cyclotorsion control.
Eyes with primary simple or compound hyperopic astigmatism and a cylinder power ≥3.00 D had uneventful femtosecond laser-assisted LASIK with a fast repetition rate excimer laser ablation, aspheric profiles, and cyclotorsion control. Visual, refractive, and aberrometric results were evaluated at the 3- and 6-month follow-up. The astigmatic outcome was evaluated using the Alpins method and ASSORT software.
This study enrolled 80 eyes at 3 months and 50 eyes at 6 months. The significant reduction in refractive sphere and cylinder 3 and 6 months postoperatively (p<0.01) was associated with an improved uncorrected distance visual acuity (p<0.01). A total of 23.75% required retreatment 3 months after surgery. Efficacy and safety indices at 6 months were 0.90 and 1.00, respectively. At 6 months, 80% of eyes had an SE within ±0.50 D and 96% within ±1.00 D. No significant differences were detected between the third and the sixth postoperative months in refractive parameters. A significant increase in the spherical aberration was detected, but not in coma. The correction index was 0.94 at 3 months.
Laser in situ keratomileusis for primary compound hyperopic astigmatism with high cylinder (>3.00 D) using the latest excimer platforms with cyclotorsion control, fast repetition rate, and optimized aspheric profiles is safe, moderately effective, and predictable.
使用具有优化非球面轮廓和旋转扭转控制的快速重复率准分子激光平台，评估飞秒激光辅助原位角膜磨镶术（LASIK）矫正伴有高度柱镜的原发性复合远视散光后的视觉效果。
患有原发性单纯或复合远视散光且柱镜度数≥3.00 D的眼睛接受了飞秒激光辅助LASIK手术，采用快速重复率准分子激光消融、非球面轮廓和旋转扭转控制。在术后3个月和6个月时评估视觉、屈光和像差结果。使用阿尔平斯方法和ASSORT软件评估散光结果。
本研究在3个月时纳入80只眼，6个月时纳入50只眼。术后3个月和6个月时屈光球镜和柱镜的显著降低（p<0.01）与未矫正远视力的改善相关（p<0.01）。共有23.75%的患者在术后3个月需要再次治疗。6个月时的疗效和安全指数分别为0.90和1.00。6个月时，80%的眼睛的等效球镜度数在±0.50 D以内，96%在±1.00 D以内。术后第3个月和第6个月的屈光参数之间未检测到显著差异。检测到球差显著增加，但彗差未增加。3个月时的矫正指数为0.94。
使用具有旋转扭转控制、快速重复率和优化非球面轮廓的最新准分子激光平台，对伴有高度柱镜（>3.00 D） 的原发性复合远视散光进行原位角膜磨镶术是安全、中度有效且可预测的。
