肝素处理人工晶体在儿童白内障手术中的应用

Heparin-Surface-Modified intraocular lens implantation in pediatric cataract

目的 :观察肝素表面处理人工晶体 (Heparin -Surface -ModifideIOL简称HSM -IOL)在儿童白内障手术中的应用 ;方法 :对 2 5例儿童白内障患者行针吸术 ,1 2例植入HSM—IOL ,1 3例植入普通聚甲基丙烯酸甲酯人工晶体 (PolymethylMethacry lateIOL简称PMMA—IOL) ,对两组术后视力、眼前节反应及后囊混浊进行对比分析 ;结果 :二组术后视力无显著性差异 (P >0 0 5 ) ,晶体表面色素沉着及纤维蛋白渗出在术后 2周时差异有显著性 (P <0 0 5 ) ,术后 6个月后囊混浊HSM组明显低于PMMA组(P <0 0 5 ) ;结论 :HSM—IOL可使儿童白内障术后反应和后囊混浊的发生率降低。

Objective:To observe the results of heparin-surface-modified intraocular lens implanted in pediatric cataract;Methods:In 25 cases of pediatric cataract were performed with aspiration,12 eyes received HSM-IOL and 13 eyes with PMMA-IOL.The postoperative vision,anterior chamber reaction and posterior capsular opacity were analysed between the two groups;Results:Between two groups,there is no significant difference in postoperative vision.There is significant difference in fibrinous exudate and pigment dispertion in two weeks,and posterior capsular opacity in six months;Conclusion:HSM-IOL can reduce the reaction in anterior chamber and posterior capsular opacity after surgery.
