AIM: To compare the clinical effects of two different surgical ways on congenital cataract.

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.
