方法：对60例60眼皮质液化白色膨胀白内障随机分组。观察组30例患者，撕囊镊直接撕囊； 治疗组30例患者，压核排液后进行撕囊。

结果：在初步破囊时，有前囊膜自动裂向周边现象，观察组有9例，治疗组有10例，差异无统计学意义(P>0.05)。观察组连续环形撕囊的成功率为26.7%，治疗组撕囊成功率66.7%，差异有显著统计学意义(P<0.01)。观察组2例患者术中后囊自发破裂，治疗组无后囊破裂情况发生。

结论：在白色膨胀白内障手术中，应用压核排液处理后，液化皮质的流出可消除晶状体核的上浮对前囊膜撕囊的影响，并可显著提高此类白内障中连续环形撕囊的成功率。

METHODS: Sixty cases of white cortical liquefaction cataract were divided randomly into 2 groups. Thirty patients of the observation group were performed capsulorhexis with capsulorhexis forceps directly. The treatment group of 30 patients were operated the capsulorhexis after pressing nucleus with capsulorhexis to discharge of liquid in lens capsule.

RESULTS: In the initial broken capsule, the anterior capsule automatically split to the surrounding circumstances. There were 9 cases in the observation group, 10 cases in the treatment group(P>0.05). The observation group CCC success rate was 26.7%, the treatment group 66.7%(P<0.01). In the observation group, 2 patients underwent spontaneous rupture of the posterior capsule, in the treatment group, it did not happen.

CONCLUSION: In the white inflation cataract surgery, the use of pressing lens nucleus to outflow of liquefied cortex can eliminate the effect of lens nucleus of upward floating on anterior capsule capsulorhexis. It significantly improves the success rate of CCC.
