To evaluate surgically induced changes in corneal, internal, and ocular higher-order aberrations (HOAs) after phakic intraocular lens (PIOL) implantation and compare them between two PIOLs with different pupillary diameters.
Twenty-three eyes with an Artisan PIOL (Ophtec BV, Groningen, The Netherlands) (Artisan group) and 30 eyes with an Artiflex PIOL (Ophtec BV) (Artiflex group) were retrospectively evaluated. The corneal, internal, and ocular HOAs and refractive data were recorded preoperatively and 6 months postoperatively. The root mean squares (RMSs) of the total HOAs from the third- to sixth-order Zernike coefficients were calculated. The RMSs of the third- and fourth-order coefficients represented coma-like aberrations (S3) and spherical-like aberrations (S4), respectively. The main outcome measures were the differences in the parameters among the groups with different pupillary diameters.
The mean postoperative spherical equivalents decreased from -11.84 ± 4.90 to -0.16 ± 0.40 diopters and -9.78 ± 3.20 to -0.09 ± 0.26 diopters in the Artisan and Artiflex groups, respectively. With the 4- and 5-mm pupillary diameters, the postoperative internal and ocular spherical aberrations (Z4(0)) were significantly lower in the Artiflex group than in the Artisan group (4 mm, P = .002, .024; 5 mm, P = .004, .022, respectively). With the 6-mm pupillary diameter, there were no significant postoperative differences in any parameter measured between groups; both groups had positive spherical aberration values.
The postoperative ocular spherical aberrations were positive after Artisan and Artiflex implantation. The postoperative ocular spherical aberration was greater in the Artisan group, possibly due to differences in the SAs of both PIOLs.
评估有晶状体眼人工晶状体（PIOL）植入术后角膜、眼内和眼高阶像差（HOA）的手术诱导变化，并比较两种瞳孔直径不同的 PIOL 之间的差异。
回顾性分析 23 只眼行 Artisan PIOL（荷兰 Groningen Ophtec BV）植入术（Artisan 组）和 30 只眼行 Artiflex PIOL（荷兰 Groningen Ophtec BV）植入术（Artiflex 组）。分别于术前和术后 6 个月记录角膜、眼内和眼 HOA 及屈光数据。计算第三到第六阶泽尼克系数的总 HOA 的均方根（RMS）。第三和第四阶系数的 RMS 分别代表彗差像差（S3）和球差像差（S4）。主要观察指标是不同瞳孔直径组之间各参数的差异。
Artisan 组和 Artiflex 组术后平均等效球镜从-11.84±4.90 至-0.16±0.40 屈光度和-9.78±3.20 至-0.09±0.26 屈光度分别下降。在 4-mm 和 5-mm 瞳孔直径时，Artiflex 组术后眼内和眼总球差（Z4（0））明显低于 Artisan 组（4-mm，P=0.002，0.024；5-mm，P=0.004，0.022）。在 6-mm 瞳孔直径时，两组间测量的各参数术后均无显著差异；两组均有正性球差。
Artisan 和 Artiflex 植入术后眼总球差为正性。Artisan 组术后眼总球差较大，可能与两种 PIOL 的 SA 不同有关。
