To determine the characteristics of astigmatism 1 week postoperatively or whether the final astigmatism is predictable from that present 1 week postoperatively, we analyzed 544 postcataract against-the-rule (AR) cases of astigmatism among 1,649 standard phacoemulsification cataract operations, all utilizing 10-0 Mersilene in double-running fashion. Postoperative AR astigmatism < or = 1.0 dpt increased markedly 1 week postoperatively (2.72 +/- 0.09 dpt) but decreased 6 months postoperatively. However, in postoperative AR astigmatism > 2.0 dpt, the increase 1 week postoperatively was not as great (2.16 +/- 0.13 dpt) but tended to continue to increase even 6 months postoperatively, with a flatter corneal curvature being the responsible factor. Eyes with less astigmatism 1 week postoperatively showed exacerbation of final astigmatism 6 months postoperatively. This course was different from that of small incision cataract surgery.
为了确定术后1周散光的特征，或者最终散光是否可根据术后1周时的散光情况预测，我们分析了1649例标准超声乳化白内障手术中的544例白内障术后逆规（AR）散光病例，所有病例均采用10-0涤纶线双行缝合。术后AR散光≤1.0屈光度在术后1周时显著增加（2.72±0.09屈光度），但在术后6个月时下降。然而，术后AR散光>2.0屈光度时，术后1周的增加幅度没那么大（2.16±0.13屈光度），但甚至在术后6个月时仍有继续增加的趋势，角膜曲率变平是其原因。术后1周散光较小的眼睛在术后6个月时最终散光加重。这个过程与小切口白内障手术不同。
