方法：回顾性分析我院眼科中心2011-01/2014-08收治的82例87眼先天性白内障患儿的临床及术后随访资料，根据手术方式分为对照组(38例40眼，采用超声乳化晶状体吸出术+后囊膜连续环形撕囊)、研究组(44例47眼，用超声乳化晶状体吸出术+后囊膜连续环形撕囊+前部玻璃体切割术)，比较两组患者的术中、术后并发症，术后1a随访中央视轴区混浊的发生率及术后两组患儿视力分布的情况差异。

结果：对照组中央视轴区混浊0级所占比例为37.5%，低于研究组的76.6%，研究组的1级、2级、3级、4级混浊分布比例均低于对照组患儿，研究组的中央视轴区混浊分布显著优于对照组(P<0.05)。对照组患儿视力检测≤0.5者19眼(47.5%)，高于研究组7眼(14.89%)，对照组>0.5者21眼(52.5%)，低于研究组者40眼(85.11%)，两组患儿术后1a的视力检测比较差异具有统计学意义(P<0.05)，研究组显著优于对照组。两组患者术后第1mo，1a的眼压较术前均显著降低(P<0.05)，但组间比较差异不具有统计学意义(P<0.05)。

结论：用超声乳化晶状体吸出术+后囊膜连续环形撕囊+前部玻璃体切割术治疗先天性白内障能够显著降低术后中央视轴区混浊程度，同时提高术后视力，能够有效降低后发性白内障的形成。

METHODS: Postoperative clinical follow-up data of 82 cases(87 eyes)with congenital cataract treated in Eye Center of our hospital from January 2011 to August 2014 were retrospectively analyzed. The patients were divided into the surgical control group(38 cases, 40 eyes, recieved phacoemulsification + PCCC)and the study group(44 cases, 47 eyes, accepted phacoemulsification + PCCC + anterior vitrectomy). The incidence of central optic axis opaque and postoperative visual acuity distribution were recorded at 1a follow-up. Intraoperative and postoperative complications were observed.

RESULTS: The rate of central optic axis opaque grade 0 in control group was 37.5%, compared to 76.6% in study groups. The opacity distribution ratio of grade 1,2,3 and 4 in study group were lower than that of control group, and the central optic axis opacity distribution ratio in study group was significantly better than that of control group(P<0.05). The 19 eyes(47.5%)of visual acuity testing ≤0.5 in control group, was higher than the 7 eyes(14.89%)of that in the study group, The 21 eyes(52.5%)of visual acuity testing >0.5 in control group was lower than the 40 eyes(85.11%)of that in study group. The visual acuity between two groups has statistical significance difference after 1a follow-up(P<0.05), and the visual acuity in study group was significantly better than that in the control group. The postoperative intraocular pressure at 1mo and 1a follow-up was lower than before operation in two groups(P<0.05), but there was no significant difference between two groups in intraocular pressure(P<0.05).

CONCLUSION: Combination of phacoemulsification, PCCC and anterior vitrectomy presents reliable clinical effects on postoperative central optic axis opacity distribution ratio and visual acuity, and it should be adopted to prevent the occurrence of posterior capsule opacification.
