老年性白内障人工晶体植入术后并发症的原因分析及处理

The causes and management of complications in posterior chamber intraocular lens implantation in senile cataract

目的 :研究老年性白内障人工晶体植入术后并发症的原因和治疗措施。方法 :为 5 10例老年性白内障行现代囊外摘除、后房型人工晶体植入术 ,术后检查视力、眼压、眼底等 ,随访 8～ 2 4个月。结果 :术后角膜内皮混浊、皱折 2 96例 ,占 5 8.0 4 ;前房炎性反应 79例 ,占 15 .5 % ;晶体前膜 2 1例 ,前房出血 8例 ,眼压高 12例 ,瞳孔散大 6例 ,移位 12例 ,人工晶体偏位 14例 ,后囊膜混浊 4例。结论 :老年性白内障囊外摘除、人工晶体植入术后并发症形成的主要原因是操作不熟练 ,器械反复进入前房 ,以及进入前房的物质质量不可靠 ,操作熟练 ,进入前房稳定的物质质量 ,可减少术后并发症的发生。

Objective:To research the causes and management of the postoperative complications in extracapsular cataract extraction(ECCE) and intraocular lens(IOL) implantation.Method:ECCE and IOL implantation were performed on 510 cases with senile cataract.The postoperative vision,intraocular pressure(IOP),and eyeground were examined.287 eyes were followed up for 8～24 months.Results:After operation,corneal edema occured in 296 eyes;postoperative reactions,in 79 eyes;anterior chamber exudation,in 21 eyes;hyphema,in 8 eyes;increased tension,in 12 eyes;enlarged iris,in 6 eyes;dislocation of iris,in 12 eyes;dislocation of intraocular lenses,in 14 cases;postior capsule opacity,in 4 eyes.Conclusion:The causes of the postoperative complications of extracapsular cataract extraction (ECCE) and IOL implantation were unskilled operations,more operations in anterior chamber and stale qualities of substance entered into anterior chamber.So skilled operations,stable qualities,active preventions can reduce the postoperative complications.
