Use of 10-0 monofilament nylon in ECCE cataract surgery leads to high with the rule astigmatism. Many intraoperative and post operative methods have been used to minimise post operative astigmatism. We did selective suture cutting in 38 consecutive patients. Mean keratometric astigmatism at three and six weeks post operative was 5.76 and 5.42 dioptres (D) respectively. 77.5% of eyes had astigmatism above 2 D. Selective suture cutting along the axis of the plus high cylinder was done after six weeks of surgery. Mean post suture cutting keratometric astigmatism was 3.3 D and 70% of the eyes had astigmatism below 2 D. After 3 months of surgery mean keratometric astigmatism was reduced to 1.84 D. Axis of the astigmatism also changed following suture cutting. 40% of the eyes showed improvement in their Snellen acuity following reduction in the cylindrical power.
在白内障囊外摘除术（ECCE）中使用10-0单丝尼龙线会导致顺规散光程度较高。人们已经采用了许多术中及术后方法来尽量减少术后散光。我们对38例连续患者进行了选择性缝线拆除。术后3周和6周时角膜散光平均分别为5.76和5.42屈光度（D）。77.5%的眼睛散光度数高于2D。术后6周后沿正高柱镜轴进行选择性缝线拆除。缝线拆除后角膜散光平均为3.3D，70%的眼睛散光度数低于2D。术后3个月时角膜散光平均降至1.84D。散光轴在缝线拆除后也发生了变化。40%的眼睛在柱镜度数降低后视力表视力有所改善。
