To evaluate higher-order aberrations (HOAs) after implantation of Artiflex phakic intraocular lenses (pIOLs).
Department of Ophthalmology, Academic Hospital Maastricht, Maastricht, The Netherlands.
This retrospective comparative case series comprised 27 eyes (14 patients) that had Artiflex pIOL implantation and 22 eyes (13 patients) that had Artisan pIOL implantation. Refractive data, pupil size, IOL decentration, and HOA values were recorded and compared. Laboratory analysis was performed. Follow-up was 1 year.
In the Artiflex group, the mean spherical equivalent (SE) changed from -9.95 diopters (D) +/- 1.43 (SD) (range -6.75 to -12.13 D) to -0.30 +/- 0.53 D (range -1.94 to 0.56 D). Postoperatively, trefoil-y increased (increase factor 1.73) and spherical aberration decreased (increase factor 0.55). The mean pIOL decentration was 0.24 +/- 0.12 mm; 96.3% were decentered 0.5 mm or less. There was a significant correlation between pIOL decentration and postoperative spherical aberration and coma-y. In the Artisan group, the mean SE changed from -9.90 +/- 2.74 D (range -4.00 to -14.50 D) to -0.20 +/- 0.42 D (range -0.75 to 0.50 D). Postoperatively, trefoil-y and spherical aberration increased (increase factors 3.32 and 6.84, respectively). Laboratory analysis confirmed the negative and positive spherical aberration profile of the Artiflex pIOL and Artisan pIOL, respectively.
Artiflex pIOL implantation decreased spherical aberration, while Artisan pIOL implantation increased spherical aberration. Trefoil-y increased in both groups. These changes might be explained by incision size differences in relation to trefoil and differences in optic design in relation to spherical aberration.
评估Artiflex有晶状体眼人工晶状体（pIOL）植入术后的高阶像差（HOA）。
荷兰马斯特里赫特学术医院眼科。
本回顾性比较病例系列包括27只眼（14例患者）接受了Artiflex pIOL植入，以及22只眼（13例患者）接受了Artisan pIOL植入。记录并比较屈光数据、瞳孔大小、人工晶状体偏心度和高阶像差数值。进行实验室分析。随访1年。
在Artiflex组，平均球镜等效度（SE）从-9.95屈光度（D）±1.43（标准差）（范围-6.75至-12.13 D）变为-0.30±0.53 D（范围-1.94至0.56 D）。术后，三叶状像差-y增加（增加因子1.73），球差降低（增加因子0.55）。人工晶状体平均偏心度为0.24±0.12 mm；96.3%的偏心度在0.5 mm或更小。人工晶状体偏心度与术后球差和彗差-y之间存在显著相关性。在Artisan组，平均SE从-9.90±2.74 D（范围-4.00至-14.50 D）变为-0.20±0.42 D（范围-0.75至0.50 D）。术后，三叶状像差-y和球差增加（增加因子分别为3.32和6.84）。实验室分析分别证实了Artiflex pIOL和Artisan pIOL的负球差和正球差特征。
Artiflex pIOL植入降低了球差，而Artisan pIOL植入增加了球差。两组的三叶状像差-y均增加。这些变化可能与三叶状像差相关的切口大小差异以及球差相关的光学设计差异有关。
