方法：选择2009-12/2012-12在我院行白内障手术治疗的患儿52例84眼，按手术方式分为两组：A组超声乳化吸除+后囊膜环形撕开，B组采用超声乳化吸除+后囊膜环形撕开+前节玻璃体切割术。术后随访6～12mo，并记录术后视力以及并发症情况。

结果：所有患儿术后矫正视力较术前均有提高，差异有统计学意义(P<0.05)； 两组患儿术前视力差异无统计学意义(P>0.05)，而术后矫正视力差异有统计学意义(P<0.05)，B组矫正视力高于A组； 两组术后并发症比较，仅后囊膜混浊(posterior capsule opacification，PCO)差异有统计学意义(P<0.05)，B组术后PCO发生率(12%)远低于A组(53%)，其他并发症组间差异均无统计学意义(P>0.05)。

结论：与超声乳化吸除+后囊膜环形撕开相比，联合了前节玻璃体切割的手术方式能更好的改善术后矫正视力和减少PCO的发生。

METHODS: We selected 52 children(84 eyes)with congenital cataract surgery between December 2009 and December 2012 in our hospital. They were divided into two groups based on the surgical way: A group were treated by phacoemulsification+posterior curvilinear capsulorhexis, B group were treated by phacoemulsification+posterior curvilinear capsulorhexis+anterior vitrectomy. The follow-up was 6-12mo, and postoperative corrected visual acuity and complications were observed.

RESULTS: Postoperative visual acuity of two groups were increased(P<0.05). Preoperative visual acuity between two groups had no significant difference(P>0.05), while postoperative visual acuity between two groups had significant difference(P<0.05), group B was better than group A. Complications had no significant difference between two groups except posterior capsule opacification(PCO)(P<0.05). The incidence rate of PCO in group B(12%)was far lower than group A(53%).

CONCLUSION: Compare with phacoemulsification + posterior curvilinear capsulorhexis, the way combined with anterior vitrectomy can improve the postoperative visual acuity and decrease the incidence rate of PCO.
