摘　　要：目的探讨改良折叠型人工晶状体缝线固定术后角膜表面形态、屈光状态的改变。方法对2012年6月至2014年5月在唐山市眼科医院应用改良折叠型人工晶状体缝线固定术治疗眼外伤晶状体玻璃体切除术后患者23例（23只眼），运用角膜地形图仪检查术前，术后3d、1周、1个月、3个月的角膜散光变化。结果平均角膜散光度术后1个月较1周明显减少，两者比较有显著性差异，3个月与1个月比较无显著性差异，即1个月时视力明显提高且趋于稳定。结论改良折叠型人工晶状体缝线固定术具有术后角膜散光小，视力恢复快等优点，早期即可得到良好的手术效果。Objective To investigate the changes of appearance of comeal surface and refraction after using modified operation with IOL Delivery System secondary foldable intraocular lens with su- ture fixation. Methods Twenty-three patients （23 eyes） who underwent foldable intraocular with su- ture fLxation by modified operation, corneal topography was used to analyze preoperatively and at 3 days, 1 week, 1 month, 3 months postoperatively. Results Average corneal astigmatism was de- creased obviously 1 month after operation compared with 1 week after operation. There was not sig- nificant difference between 3 months and 1 month. Conclusions The changes of corneal topography are not obvious after using modified operation with IOL Delivery System secondary foldable intraocu- lar lens with suture fixation, and have a better operation effect in the early stage.
