Continuous curvilinear capsulorhexis (CCC) has become a standard procedure in cataract surgery. In pediatric cataracts, however, this technique is difficult to perform. Because of the elasticity and tension of the pediatric anterior lens capsule the danger of radial tears is high. Similar conditions are found in the rabbit model. The anterior lens capsule of young albino rabbits is very elastic. We have developed a CCC technique in rabbits that allows a controlled round capsular opening. This technique was used in an experimental study with 16 rabbits (32 eyes). The mean capsulorhexis diameter was 4.9 +/- 0.9 mm. A radial tear occurred in only 2/32 cases. The technique permits a controlled circular anterior capsulectomy for capsules with high surface tension and elastic properties. This can readily be applied to human pediatric cases.
连续环形撕囊术（CCC）已成为白内障手术的标准术式。然而，在儿童白内障手术中，该技术实施起来较为困难。由于儿童晶状体前囊的弹性和张力，出现放射状撕裂的风险很高。在兔模型中也存在类似情况。幼年白化兔的晶状体前囊非常有弹性。我们在兔身上开发了一种CCC技术，可实现可控的圆形囊膜开口。该技术用于一项对16只兔子（32只眼）的实验研究。平均撕囊直径为4.9 +/- 0.9毫米。仅2/32例出现放射状撕裂。该技术可对具有高表面张力和弹性特性的囊膜进行可控的圆形前囊切除术。这可很容易地应用于人类儿童病例。
