AIM: To evaluate the effect of complete circular continuous capsulorhexis(CCC)in white inflation cataracts after pressing nucleus to discharge of liquid in lens capsule.

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.
