小儿白内障后囊破裂人工晶状体植入术探讨

The surgical choice of cataract extraction and int raocular lens implantation in children with posterior-capsule rupture.

目的 探讨小儿白内障后囊不完整时Ⅰ期后房型人工晶状体植入术和Ⅱ期人工晶状体植入术两种术式的效果。方法 小儿白内障术前或术中后囊破裂2 7例(3 9眼)。分为两组:A组18例(2 6眼) ,行Ⅰ期后房型人工晶状体植入术,B组9例(13眼) ,未行人工晶状体植入或行Ⅱ期植入术,术后随访1年,比较两组的视力。结果 两组视力差异有显著意义(P <0. 0 5 ) ,B组的并发症多。结论 应重视小儿白内障手术的质量,以避免术中并发症的发生或尽量实行Ⅰ期人工晶状体植入。

Objective To evaluate the different effects of c a taract extraction with posterior-chamber intraocular lens implantation or secon dary posterior-chamber intraocular lens implantation in children with posterior -capsule rupture. Methods 27 cases(39 eyes) were selected according to posterior -capsule rupture before or in operation from February,1999 to Decembr,2001 in o ur hospital.These cases were divided into two group,group A has 18 cases(26 eye s) which were treated with cataract extraction and posteriou-chamber intraocula r lens implantation,group B has 9 cases(13 eyes )which were treated with catara ct extraction and secondary posterior-chamber intraocular lens implantation or cataract extraction only. Follow-up 1 year,compare the visual acuity of two gr oup. Results The visual acuity of two group has significant difference (P<0.05), group B has more complications. Conclusion Cataract extraction with posterior-chamber intraocula r lens implantation is more helpful for children with posterior-capsule rupture .
