To assess residual postoperative refractive astigmatism following bilateral implantation of a trifocal toric intraocular lens (IOL) in a real-world multisurgeon setting.
Prospective multisurgeon study (6 surgeons at 2 sites).
Bilateral implantation of a trifocal toric IOL (AcrySof PanOptix IOL; Alcon Vision LLC, Fort Worth, TX, USA) was performed in 140 eyes of 70 patients. Patients were assessed on day 1 and 3 months postoperatively. The primary outcome measure was residual astigmatism. Secondary endpoints included absolute prediction error, IOL rotation, binocular uncorrected and distance-corrected visual acuities at near (40 cm), intermediate (60 cm), and distance (6 m) and spectacle independence evaluated with the validated Intraocular Lens Satisfaction questionnaire.
Mean preoperative cylinder was 1.25 ± 0.72 D and was 0.39 ± 0.28 D at 3 months postoperatively. At 3 months postoperatively, mean residual astigmatism was 0.39 ± 0.28 D (range, 0-1.25 D), and 118 eyes (84.3%) had postoperative astigmatism of 0.5 D or less. Mean absolute prediction error was 0.25 ± 0.21 D (range, 0-1.13 D), and 124 eyes (88.6%) had absolute prediction error of 0.5 D or less. At 3 months postoperatively, mean absolute rotation was 2.0 ± 2.7 degrees compared with baseline (range, 0-15 degrees), and 133 IOLs (95.0%) were within 5 degrees of the implanted axis. Additionally, 55 patients (79%) reported never or rarely using spectacles at near, 66 (94%) at intermediate, and 67 (96%) at distance.
The results of this study demonstrate that implantation with the PanOptix toric IOL can provide excellent refractive and visual outcomes with minimal residual astigmatism.
评估在真实多手术医生环境下双侧植入三焦点散光人工晶状体（IOL）后残余术后屈光性散光。
前瞻性多手术医生研究（2 个地点的 6 名医生）。
在 70 名患者的 140 只眼中进行双侧植入三焦点散光人工晶状体（Acrysof PanOptix IOL；Alcon Vision LLC，德克萨斯州沃思堡）。患者在术后第 1 天和第 3 个月进行评估。主要结局指标是残余散光。次要终点包括绝对预测误差、IOL 旋转、双眼未矫正和距离矫正的近视力（40cm）、中间视力（60cm）和远视力（6m）以及使用经过验证的人工晶状体满意度问卷评估的眼镜独立性。
平均术前散光为 1.25±0.72D，术后 3 个月为 0.39±0.28D。术后 3 个月，平均残余散光为 0.39±0.28D（范围，0-1.25D），118 只眼（84.3%）术后散光为 0.5D 或更低。平均绝对预测误差为 0.25±0.21D（范围，0-1.13D），124 只眼（88.6%）的绝对预测误差为 0.5D 或更低。术后 3 个月，平均绝对旋转为 2.0±2.7度，与基线相比（范围，0-15度），133 个 IOL 中有 133 个（95.0%）在植入轴的 5 度以内。此外，55 名患者（79%）报告在近距、66 名患者（94%）在中距和 67 名患者（96%）在远距从不或很少使用眼镜。
这项研究的结果表明，植入 PanOptix 散光 IOL 可以提供极好的屈光和视觉效果，残余散光最小。
