先天性白内障后发障形成的危险因素分析

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:对53例(87眼)先天性白内障患者行巩膜隧道切口白内障摘除术,其中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)、手术年龄小于1岁(P<0.05)及I期植入IOL(P<0.05)有关。结论:手术年龄越小、I期植入IOL及保持后囊完整是PCO形成的危险因素。

Risk factors for the posterior capsule opacification after cataract surgery

Objective: To evaluate the factors that lead to posterior capsule opacification(PCO) in cataract extraction.Methods: The clinical data of 53 patients with congenital cataract(87 eyes) reveiving cataract extraction through a scleral tunnel incision were retrospectively analyzed.Of them,the posterior capsule was left in 35 eyes,primary posterior continuous curricular capsulectomy(PCCC) was performed in 19 eyes,PCCC with an anterior vitrectomy(AV) in 33 eyes, and primary intraocular len(IOL) implantation in 51 eyes.Results: During a follow-up of 18 months,PCO occurred in 30 eyes(34.48%),including intact posterior capsule in 19(54.29%) eyes,PCCC in 5(26.32%) eyes,PCCC+AV in 6(18.18%) eye,which may due to not performing PCCC+AV(P<0.01) or implantating primary IOL(P<0.05).Conclusion: Young in age,primary IOL implantation and intact posterior capsule are the risk factors for the formation of PCO.
