后囊膜混浊的相关因素分析

目的:探讨在白内障及人工晶状体植入后,后囊膜混浊的相关因素以及预防治疗的方法。方法:根据手术方法分为单纯白内障摘除组及白内障加人工晶状体植入组,后者又根据手术方法的不同及人工晶状体的类型进行比较分析。结果:单纯摘除组与人工晶状体植入组,人工晶状体植入中,不同的手术方法及不同的人工晶状体类型其后囊膜混浊发生的频率及程度均存在较大差异。结论:选择适宜的手术方法(完全封闭技术)、优良的人工晶状体材质(疏水性丙烯酸酯和肝素处理)、特殊的形态设计(锐利边缘)就能最大程度的减少或避免后囊膜混浊的发生。

Analysis of related factors of posterior capsular opacification

AIM:To discuss the related factors of posterior capsular opacification after intraocular lens implantation and cataract surgery,to find prevention and treatment methods.· METHODS:The patients were divided into two groups by surgical methods:group 1 with extirpating cataract and group 2 with extirpating cataract plus lens implantation.We compared and analyzed the results of group 2 according to different surgical methods and lens types.· RESULTS:There were significant differences in capsular opacification occurrence rate and degree between group 1 and group 2.The difference was also associated with surgical methods and lens types.· CONCLUSION:The results show that if we choose right surgical method(completely obturated technology),good lens(dealing with hydrophobicity acrylate and heparin)and special shape design(sharp edge),we can reduce or avoid the occurrence of capsular opacification to the greatest extent.
