小儿白内障摘除联合后房型人工晶体植入的临床观察

Clinical Observation on Extraction of Cataract with Posterior Chamber Intraocular Lens Implantation in Children

目的 观察小儿白内障摘除联合后房型人工晶体植入术的治疗效果。 方法 小儿白内障患者 87例 ( 10 3眼 ) ,年龄 2～ 14岁。手术行白内障摘除联合后房型人工晶体植入 ,术中行后囊连续环形撕囊 (PCCC)、前段玻璃体切除及人工晶体后囊夹持 ,术后随访 1～ 36 (平均 7.8)个月。结果 术后视力 >0 .0 5者 83眼 ,0 .1～ 0 .3者 6 6眼 ,最佳校正视力 >0 .5者 2 6眼 ,其中脱盲率 80 .6 %。术后并发症主要为葡萄膜炎 ( 31.1% )、后发障 ( 30 .1% )和角膜水肿 ( 9.7% )等。结论 及时摘除小儿白内障 ,植入后房型人工晶体 ,术中联合PCCC、前段玻璃体切除和人工晶体后囊夹持的方法可有效提高患眼视功能 。

Objective To investigate the effects of extraction of cataract with posterior chamber intraocular lens (IOL) implantation in children.Methods One hundred and three eyes in 87 children aged from 2 to 14 years were treated with cataract extraction and posterior chamber intraocular lens implantation. During the operation, posterior continuous curvilinear capsulorhexis (PCCC), anterior vitrectomy and posterior capsular trap of intraocular lens were performed. Then the children were followed up from 1 to 36 months (mean 7.8 months).Results Eighty-three (80.6%) eyes were relieved from blindness, 66 eyes got visual acuity (VA) of 0.1～0.3 and the best corrected VA of 26 eyes was 0.5 or better. The postoperative complications were mostly uveitis (31.1%), after cataract (30.1%), corneal edema (9.7%) and so on.Conclusion Timely cataract extraction and posterior chamber IOL implantation, combined with PCCC, anterior vitrectomy and posterior capsular trap of IOL can effectively improve the visual acuity and prevent the formation of after cataract in children.
