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。
