完善的白内障囊外摘除术(ECCE)和人工晶体(IOL)植入术的成功率已在95%以上。两个主要远期并发症是后囊混浊(posterior capsule opacification PCO)(包括后发障、囊膜纤维化和上皮珍珠样小体)和与PCO紧密相关的人工晶体偏中心。近年来PCO的预防受到了越来越广泛的重视,现就有关研究进展综述如下: 1 PCO的发生率及其原因晶体上皮细胞的增殖和移行可形成PCO,术前存在的后囊下型白内障即由此产生。Wihelmus和Emery报道的术后发生PCO的平均时间是术后26
Successful cataract extraction (ECCE) and intraocular lens (IOL) implantation rate of more than 95%. The two main long-term complications are posterior capsule opacification (PCO) (including posterior capsular disorders, capsular fibrosis and epithelial pearl-like bodies) and intraocular lens centers closely related to PCO. The prevention of PCO in recent years has been more and more attention, and now on the progress of the research are summarized as follows: 1 The incidence of PCO and its causes The proliferation and migration of the lens epithelial cells can form PCO, postoperative pre-subcapsular cataract That is the result. The average time to postoperative PCO reported by Wihelmus and Emery was 26 postoperatively
