目的　分析超声乳化术中电子与手工连续环形撕囊2种方法的临床特点及晶状体囊膜边缘的病理结果。方法　对随机抽取的电子与手工连续环形撕囊各 5 0例 5 0眼进行随访。取部分前囊膜行病理检查。结果　病理切片显示 :电子环形撕囊的前囊膜反卷、增厚重叠在一起 ,晶状体上皮细胞排列失去规则。在超声乳化及人工晶状体植入的过程中电子环形撕囊的囊膜边缘较手工环形撕囊易撕裂。手工环形撕囊的囊膜边缘上皮细胞排列整齐 ,不易发生撕裂。结论　对于初学者及某些特殊类型的白内障 ,电子环形撕囊简单易操作 ,同时对于手工撕囊失败的病例是一种有效的补救方法 ,但有撕囊口易撕裂的缺点。 Objective To analyze the clinical features of phacoemulsification and electronic manual loop capsulotomy and the pathological findings of the lens capsule rim. Methods A total of 50 cases of 50 cases of electronic and manual continuous circular capsulorhexis were randomly followed up. Take part of the anterior capsule line pathological examination. Results The pathological sections showed that the anterior capsule of the electronic toroidal capsulorhexis was unwound and thickened, and the arrangement of lens epithelial cells was lost. In the process of phacoemulsification and intraocular lens implantation, the edge of the capsular membrane of the electronic toroidal capsulotomy is easier to tear than the manual toric capsulorhexis. Manual circular capsulorhexis capsule epithelial cells arranged in neat rows, not prone to tearing. Conclusion For beginners and some special types of cataract, the electronic toroidal capsulorhexis is simple and easy to operate. At the same time, it is an effective remedy for the cases of failed manual capsulorhexis. However, it has the disadvantage of easy to tear the capsulorhexis.
