The aim of this article was to demonstrate how WaveLight Contoura and wavefront optimization (WFO) can be used together to treat high myopia/myopic astigmatism corrections.
A retrospective analysis was conducted on 24 consecutive myopic/myopic astigmatism eyes that exceeded the Contoura labeling of -8.00 with -3.00 D of astigmatism. Residual correction after Contoura with Layer Yolked Reduction of Astigmatism protocol was treated with WFO Contoura LASIK correction. All patients had 3 months of follow-up. Accuracy to the desired refractive goal was assessed by postoperative refraction, regression, postoperative vision, and anecdotal subjective night vision quality.
No eyes lost best-corrected visual acuity (BCVA), and 54% of eyes gained BCVA. Out of 22 distance eyes, five achieved 20/15 or better, 18 achieved 20/20 vision, two achieved 20/25, and three achieved 20/30 vision. Preoperatively, only 14 eyes could achieve 20/20 vision. No night vision issues were observed in anecdotal reporting by patients except for those who needed enhancements that had not yet been performed.
Treatment of high myopia/astigmatism with this combination of Contoura with LYRA protocol and WFO results in excellent visual outcomes, large ablation zones on topography, and few subjective reported night vision issues.
本文旨在展示威视康（WaveLight Contoura）和波前优化（WFO）如何联合用于治疗高度近视/近视散光矫正。
对连续24只近视/近视散光眼进行回顾性分析，这些眼睛的近视度数超过威视康-8.00的标注范围，散光度数为-3.00D。采用威视康散光分层减少方案（LYRA）进行威视康手术后的残余矫正，使用WFO威视康准分子原位角膜磨镶术（LASIK）进行矫正。所有患者均进行了3个月的随访。通过术后验光、屈光度回退、术后视力以及主观夜间视力质量评估达到预期屈光目标的准确性。
无眼最佳矫正视力（BCVA）下降，54%的眼BCVA提高。在22只远距离视力眼当中，5只达到20/15或更好，18只达到20/20视力，2只达到20/25，3只达到20/30视力。术前，只有14只眼能达到20/20视力。除了那些需要增效但尚未进行的患者外，患者主观报告中未观察到夜间视力问题。
采用威视康与LYRA方案及WFO联合治疗高度近视/散光，可获得优异的视觉效果、地形图上较大的切削区，且主观报告的夜间视力问题较少。
