To determine the outcome of preoperative against-the rule (AR) astigmatism among 1,648 phacoemulsification and aspiration (PEA) procedures, we analyzed the post-cataract time course of astigmatism over 6 months in 618 eyes divided into three groups. In preoperative AR astigmatism less than 0.75 dptr (n = 208), the astigmatism increase 1 week postoperatively was rapid. In preoperative AR astigmatism greater than or equal to 1.5 dptr (n = 185), no difference in the power of astigmatism was apparent between 1 and 3 months postoperatively. The third group (0.75 less than or equal to preoperative AR astigmatism less than 1.5 dptr, n = 143) showed intermediate characteristics. The eyes with preoperative low AR astigmatism showed exacerbation of astigmatism after the PEA procedure, whereas the degree of astigmatism, corneal curvatures and the rate of AR astigmatism became lower in the eyes with higher preoperative AR astigmatism.
为了确定1648例超声乳化吸除术（PEA）中术前逆规（AR）散光的转归情况，我们将618只眼分为三组，分析了白内障术后6个月内散光的时间进程。术前AR散光小于0.75 Dptr的患者（n = 208），术后1周散光增加迅速。术前AR散光大于或等于1.5 Dptr的患者（n = 185），术后1至3个月散光度数无明显差异。第三组（术前AR散光0.75≤且＜1.5 Dptr，n = 143）表现出中间特征。术前低AR散光的眼在PEA术后散光加重，而术前AR散光较高的眼中散光度数、角膜曲率及AR散光率降低。
