摘　　要：采用截囊针撕囊法和撕囊镊撕囊法对29例31只眼白内障进行连续环形撕囊术,24只眼撕囊成功,成功率为77.4%。撕囊失败的7只眼中,4只眼因产生辐射状撕裂;2只眼因开始未形成反转小三角片;1只眼因首尾衔接不准确,均改为或补充行开罐式截囊。采用水分离术游离晶体核,无一例发生娩核困难。娩核后无一例形成前囊膜开口边缘放射状撕裂。本文对环形撕囊术的基本技术进行讨论。Continuous circular capsulorhexis(CCC)was per- formed during cataract extraction in 31 eyes of 29 cases using a bent 2S-gauge needle attached to a 1- ml.syringe or Utrata capsule forceps.In 24 of the 31 eyes(77.4%)the procedures were done successfu- lly.The other 7 eyes were performed can-opener ca- psulotomy because of the following conditions:radial capscular tears(4 eyes),unforming upturned triangular tag at the beginning(2 eyes),the two ends of the tear failiing to link up each other(1 eye).Hydrodissection was used to free the lens nucleus and there was no difficulty in delivering it in any of the 24 eyes that CCC were operated on.No radial tears on the verge of capsulor membrane were produced in any of these cases.The basic technique of CCC was discussed in this article.
