In 1991, 2,967 consecutive cataract cases were analyzed in a prospective, observational study for the incidence of intumescent cataract. Thirty four (1.15%) of the cases were mature intumescent lenses. A deliberately small continuous curvilinear capsulorhexis (CCC) enlarged secondarily by the two-stage continuous curvilinear capsulorhexis (2-CCC) technique was the anterior capsulotomy approach of choice. Depending on the liquidity of the lens material, liquid cortex was aspirated using a 26- or 30-gauge needle before capsulorhexis or through a small CCC. Because of loss of CCC control, a can-opener capsulotomy was used in three of the 34 cases before being converted by the 2-CCC technique. The rigid nucleus was usually extracted using the down-slope nucleofractis phacoemulsification technique. Four (11.7%) of the 34 intumescent cases had anterior capsule tears during capsulotomy. Successful in-the-bag lens implantation was achieved in all cases. We describe a technique of CCC, 2-CCC, and down-slope sculpting nucleofractis phacoemulsification to manage intumescent cataracts.
1991年，在一项关于膨胀期白内障发病率的前瞻性观察研究中，对2967例连续性白内障病例进行了分析。其中34例（1.15%）为成熟膨胀期晶状体。首选的前囊切开方法是采用两阶段连续环形撕囊（2-CCC）技术将故意做小的连续环形撕囊（CCC）继发扩大。根据晶状体物质的流动性，在撕囊前或通过小的CCC用26号或30号针头抽吸晶状体皮质液体。由于CCC操作失控，34例中有3例在转为2-CCC技术前采用了开罐式截囊术。硬性晶状体核通常采用下坡劈核超声乳化技术取出。34例膨胀期病例中有4例（11.7%）在截囊术中出现前囊撕裂。所有病例均成功进行了囊袋内人工晶状体植入。我们描述了一种用于处理膨胀期白内障的CCC、2-CCC及下坡雕刻劈核超声乳化技术。
