比较电凝环形撕囊与手法环形撕囊术的成功率，确定电凝撕囊术在白内障超声乳化手术中的应用价值。方法：将164例（189眼）各种不同种类的白内障分为电凝撕囊组及手法撕囊组，每组又分为容易组及困难组。结果：两容易组比较，电凝组成功率为97．4％，手法组成功率为91．4％，两组无显著性差异；两困难组比较，电凝组成功率为95．1％，手法组成功率为34．2％，两组有极显著性差异。结论：电凝环形撕囊术适合于各种类型的白内障，是一种操作简便、安全、易掌握的截囊方法。
To compare the success rate of coagulation of circular capsulorhexis and manual circular capsulorhexis to determine the value of electrocoagulation and capsulorhexis in phacoemulsification. Methods: A total of 164 cases (189 eyes) of different types of cataract were divided into electrocoagulation capsulorhexis group and manual capsulorhexis group, and each group was divided into easy group and difficult group. Results: In the two easy-to-treat groups, the power of coagulation was 97.4% and the power of hands was 91.4%. There was no significant difference between the two groups. The power of coagulation was 95.1% Power was 34.2%, there was a significant difference between the two groups. Conclusion: The coagulation enlarging capsulorhexis is suitable for all types of cataract. It is a simple, safe and easy-to-handle method for cyst closure.
