【摘要】 目的评价先天性白内障摘除术后导致晶体后囊膜混浊(PCO)的危险因素。方法53例(87眼)先天性白内障病人的临床资料。所有眼均行巩膜隧道切口白内障摘除术,35眼保持后囊膜完整、19眼行后囊连续环形撕囊(PCCC)、33眼行PCCC联合前部玻璃体切除术(AV)。51眼I期植入人工晶体(IOL)。结果平均随访时间为18个月,30眼(34.48%)发生PCO,其中后囊完整组19眼(54.29%)、PCCC组5眼(26.32%)、PCCC+AV组6眼(18.18%)。PCO的形成与术中未行PCCC+AV(P<0.01)及I期IOL植入(P<0.05)有关。手术年龄越小,PCO形成的几率越大(P<0.05)。结论手术年龄小、I期IOL植入及保持后囊完整是PCO形成的危险因素。更多还原

【Abstract】 Objective To evaluate the factors that lead to the development of posterior capsule opacification (PCO). Methods Clinical records of 53 patients with congenital cataract (87 eyes)who had cataract extraction. Cataract surgery was performed through a scleral tunnel incision in all cases. 35 eyes the posterior capsule was left intact, 19 eyes had a primary posterior continuous capsulectomy (PCCC), 33 eyes had PCCC with an anterior vitrectomy (AV), and 51 eyes were received a primay intraocular len (IOL)implantation. Results 30 eyes (34.48%) developed PCO which include 19 (54.29%) eyes with an intact posterior capsule, 5 (26.32%) eyes with PCCC, 6 (18.18%) eyes with PCCC+AV.PCO formation was associated with not perform- ing a PCCC+AV(P<0.01)and ith the implantation of a primary IOL(P<0.05).The younger the age at surgery,the more chances of PCO formation(P<0.05). Conclusions Younger age,primary IOL implantation and intact posterior capsule were the risk factors for the formation of PCO.更多还原
