We prospectively examined 94 eyes of 93 consecutive patients who had planned extracapsular cataract extraction or phacoemulsification with posterior chamber intraocular lens (IOL) implantation. The observed postoperative iris biomicroscopic modifications are described and classified. Iris synechial formation was more frequently observed in eyes with pseudoexfoliation syndrome, when an irregular anterior capsulotomy was performed, when the IOL was other than in the bag, and in cases of postoperative fibrinous exudation. Synechias occurred more frequently in intraoperatively injured iris areas. Pupil capture was the only postoperative iris modification that was observed to affect visual acuity. The maximal postoperative dilation was greater and the pupillary photic reaction was significantly less modified postoperatively (P = .0058) when the IOL was fixated within the capsular bag.
我们前瞻性地检查了93例连续患者的94只眼睛，这些患者计划进行白内障囊外摘除术或超声乳化白内障吸除术并植入后房型人工晶状体（IOL）。描述并分类了观察到的术后虹膜生物显微镜下的改变。在假性剥脱综合征患者、进行不规则前囊切开术的患者、人工晶状体未植入囊袋内的患者以及术后有纤维素渗出的病例中，虹膜粘连形成更为常见。粘连在术中受伤的虹膜区域更频繁发生。瞳孔捕获是观察到的唯一影响视力的术后虹膜改变。当人工晶状体固定在囊袋内时，术后最大瞳孔散大更大，且术后瞳孔对光反应的改变明显更小（P = 0.0058）。
