高频透热撕囊法在白内障手术中的应用

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。

Diathermic High-Frequency Capsulorhexis in Cataract Surgery

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 > or = 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.
