摘　　要：目的评价虹膜缝线固定折叠人工晶状体的临床效果。方法随机数字法将无晶状体眼62例（63眼）分成A、B两组。A组行虹膜缝线固定植入折叠人工晶状体，B组行巩膜缝线固定折叠人工晶状体，术后3个月比较两组视力和屈光状态。术后4周内，每周观察前房闪光。结果术后3个月，A组裸眼视力为（0．43±0．19）优于B组的（0．35±0．18），P〈0．05，差异有统计学意义；最佳矫正视力（BCVA）两组差异无统计学意义；术后裸眼视力：A组有38．7％（12／31）高于术前最佳矫正视力（BCVA），B组有12．5％（4／32）高于术前最佳矫正视力BCVA；A组有29％（9／31）较术前最佳矫正视力降低，B组有56．3％（18／32）较术前最佳矫正视力降低。显然验光球镜，A组成近视化趋势（-0．47±0．58）D，B组成远视化趋势（0．50±0．43）D；显然验光柱镜，A组（0．84±0．53）D小于B组（1．23±0．70）D，差异有统计学意义；角膜散光，两组差异无统计学意义；A组与B组相比，有较少并发症发生。结论短期观察，虹膜缝线固定折叠人工晶状体视力效果、屈光效果优于巩膜固定折叠人工晶状体。Objective To evaluate the clinical effects of iris- fixated foldable lens. Methods 62 patients （63 eyes） who had insufficient posterior capsular support for intraocular lens had been divided into two groups randomly, group A underwent iris-fixated foldable lens implant, group B underwent scleral-fixated foldable lens implant, 3 months after operation, visual acuity and refractive status were compared ; the first 4 weeks postoperatively, dyndall effect was observed every week. Results 3 months after operation, the UC- VA was better in group A （0.43 ±0.19）than in group B （0.35 ±0.18）, but the BCVA had no difference between the two groups; The postoperative UCVA： 12 of 31 eyes （38.7%）in group A were better than pre- operative BCVA, and the percentage in group B was 12.5% （4/32） , however, 9 of 31 eyes （29%） in group A and 18 of 32 eyes （56.3%） in group B were worse than preoperative BCVA; postoperatively, the sphere in group A was minus （ -0.47D±0.58D）, and that in group B was plus （0.50D ±0.43D）, the cylinder in group A （0.84D ±0.53D） was smaller than in group B （ 1.23D ±0.70D）, the difference was statistical significant, but the corneal astigmatism had no difference between the two groups; there were less complications in group A than in group B. Conclusion In short term, compared with group B, the visual results and refractive effects in group A were better.
