儿童白内障摘出联合后房型人工晶状体植入术的观察

The clinical observation of cataract extraction with intraocular lens implantation in children

目的 评价儿童人工晶状体植入的疗效，探讨人工晶状体屈光度的选择及并发症的防治。方法 对８５例（９６眼）４～１４岁儿童行白内障摘出及后房型人工晶状体植入术，其中先天性白内障２９眼，外伤性白内障６７眼。平均随访时间２６个月。结果除１例合并黄斑病变外，术后矫正视力普遍提高，视力＞０．０５占９８．８％，＞０．３占６８．５％，＞０．５为３１．５％。术后葡萄膜炎及后囊膜混浊较成人严重，发生率分别为７１．９％和３７．５％。结论儿童白内障通过施行白内障搞出联合后房型人工晶状体植入，绝大多数儿童的视力能显著提高，并建立良好的视功能。

ObjectiveTo evaluate the therapeutic effect of cataract extraction with intraocular lens implantation in children and to investigate the choice of IOL’s power and the prevention and treatment of complication.Methods Cataract extracapsular extraction with intraocular lens implantation was performed on 96 eyes of 85 children with age 4～14 years,including 29 eyes with congenital cataract and 67 eyes with traumatic cataract.The averaged period of follow-up was 26 months.Results All the patients received a remarkable improvement in corrected visual acuity,except 1 eye of traumatic cataract associated with maculopathy.The corrected visual acuity of >0.05,>0.3 and >0.5 were 98.8%,68.5%and 31.5%,respectively.If the ametropia is corrected in time and the amblyopia is treated for a long time,the visual acuity can be improved furtherly.Uveitis and opacification of posterior capsule were more severe than that of the adults,incidence of which were 71.9% and 37.5%,respectively.The incidence of IOL dislocation or hold and secondary glaucoma were 10.4% and 4.2%,respectively,in which the injury was more severe.Conclusion Cataract extraction with intraocular lens implantation can help most children to get a remarkable improvement in visual function.
