PURPOSE
To compare astigmatic outcomes in patients with bilateral cataracts having toric intraocular lens (IOL) implantation with intraoperative aberrometry measurements in 1 eye and standard power calculation and a toric IOL calculator with inked axis marking in the contralateral eye.
SETTING
Twelve sites in the United States.
DESIGN
Prospective cohort study.
METHODS
The eye with the more visually significant cataract was randomized to intraoperative aberrometry measurements (Ocular Response Analyzer with Verifeye) or standard preoperative biometry and use of a toric calculator with the contralateral eye automatically assigned to the other group. The primary effectiveness outcome was the proportion of eyes with a postoperative refractive astigmatism of 0.50 diopter (D) or less at 1 month.
RESULTS
Of the 130 patients (260 eyes) enrolled, 124 (248 eyes) were randomized; 121 (242 eyes) completed the trial. The percentage of eyes with astigmatism of 0.50 D or less at 1 month was higher in the intraoperative aberrometry group than in the standard group (89.2% versus 76.6%) (P = .006). The mean postoperative refractive astigmatism was lower in the intraoperative aberrometry group (0.29 D ± 0.28 [SD] versus 0.36 ± 0.35 D) (P = .041). Secondary effectiveness endpoints, including manifest refraction spherical equivalent prediction error, uncorrected distance visual acuity, and corrected distance visual acuity, were similar.
CONCLUSIONS
Compared with standard methods, the use of the intraoperative aberrometry system increased the proportion of eyes with postoperative refractive astigmatism of 0.50 D or less and reduced the mean postoperative refractive astigmatism at 1 month. Other efficacy outcomes were similar.

目的
比较双眼白内障患者在一只眼行术中像差测量并使用有标记轴位的计算软件，另一只眼行标准术前生物测量和计算软件的情况下，与仅在一只眼行术中像差测量并使用有标记轴位的计算软件，另一只眼行标准术前生物测量和计算软件的情况下，散光的术后结果。
设置
美国 12 个地点。
设计
前瞻性队列研究。
方法
选择有明显视力影响的白内障眼进行术中像差测量（利用 Ocular Response Analyzer with Verifeye）或标准术前生物测量和有标记轴位的计算软件，另一眼随机分配到另一组。主要有效性结果是术后 1 个月等效球镜度数（D）为 0.50 D 或更低的眼所占的比例。
结果
130 例患者（260 只眼）纳入研究，其中 124 例（248 只眼）随机分组，121 例（242 只眼）完成试验。术后 1 个月等效球镜度数为 0.50 D 或更低的眼在术中像差组的比例高于标准组（89.2%比 76.6%）（P=0.006）。术中像差组的平均术后屈光性散光较低（0.29 D±0.28[SD]比 0.36±0.35 D）（P=0.041）。其他有效性终点，包括视力预测误差、未矫正远视力和矫正远视力，差异无统计学意义。
结论
与标准方法相比，术中像差系统的使用提高了术后等效球镜度数为 0.50 D 或更低的眼的比例，并降低了术后 1 个月的平均术后屈光性散光。其他疗效结果相似。
