We analyzed 83 cases of remarkable postcataract against-the-rule (AR) astigmatism (greater than 1.5D) occurring in a total of 809 Kelman's phacoemulsification aspiration procedures, all using 10-0 polyester sutures in a double-running fashion to close the corneoscleral incisions. All operations were done by one surgeon, using the same surgical procedure and the same number of sutures. The induction and spontaneous regression of several types of astigmatism were analyzed over six months. In cases of preoperative oblique and AR astigmatism, shifts (2.09 +/- 0.22D, 1.93 +/- 0.13D, respectively) after the first week were much smaller than those of preoperative with-the-rule astigmatism. Thereafter, degrees of oblique and AR astigmatism increased and remained higher even six months after surgery. The induction and spontaneous regression of postoperative AR astigmatism was similar to that of oblique astigmatism. Compression of the lids on the eye may be a more important factor than previously considered.
我们分析了在总共809例凯尔曼超声乳化吸出术病例中出现的83例显著的白内障术后逆规散光（大于1.5D），所有手术均采用10-0聚酯缝线以双连续方式关闭角巩膜切口。所有手术均由一名外科医生完成，采用相同的手术步骤和相同数量的缝线。分析了六个月内几种类型散光的诱导和自然消退情况。在术前斜轴散光和逆规散光的病例中，第一周后的变化（分别为2.09±0.22D、1.93±0.13D）远小于术前顺规散光的变化。此后，斜轴散光和逆规散光的度数增加，甚至在术后六个月仍保持较高水平。术后逆规散光的诱导和自然消退与斜轴散光相似。眼睑对眼球的压迫可能是一个比之前认为的更重要的因素。
