目的:评价在白内障手术中使用高频透热撕囊仪作连续环形撕囊的效果.方法:在30例(34眼)患者进行白内障囊外摘出联合后房型人工晶体植入术中,先向前房注入透明质酸钠,然后使用高频透热撕囊仪作晶体连续环形撕囊术.结果:有3眼术中出现小的晶体前囊放射状撕裂,所有病例术后角膜无水肿,无其他术后合并症,术后一周31眼矫正视力≥0.5,占91.2％.结论:此法操作简便,易于掌握,是一个安全有效的连续环形撕囊的方法.尤其适用于过熟期白内障,儿童先天性白内障和外伤性白内障的截囊.眼科学报1999;15:121?123.“,”Purpose: To evaluate the efficiency of diathermic high-frequency capsulorhexis in cataract surgery.Methods: After injection of viscoelastic material into the anterior chamber, a continuous circular capsulotomy (CCC) was performed using a diathermic high-frequency capsulorhexis machine in 34 eyes of 30 cataract patients during extracapsular cataract extraction (ECCE) combined with intraocular lens (IOL) implantation. Results: Successfully CCC was made in 31 eyes. A small peripheral radial capsular tear was detected in 3 eyes. No postoperative corneal edema and other complications were found in all eyes. The postoperative corrected visual acuity≥0. 5 was accounted for 91.2%.Conclusion: Diathermic high-frequency capsulorhexis is a simple, safe and effective method for ECCE (or Phacoemulsification) combined with IOL implantation. It is especially indicated for those eyes with hypermature cataract, traumatic cataract and children with congenital cataract. Eye Science 1999 ; 15:121 - 123.
