Continuous curvilinear capsulorhexis (CCC) is now a standard procedure in cataract surgery. In pediatric eyes, 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 eye. The anterior lens capsule of young albino rabbits is very elastic. We 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). Mean capsulorhexis diameter was 4.9 mm +/- 0.9. A radial tear occurred in only two of 32 cases. The technique, which permits a controlled circular anterior capsulectomy for capsules with high surface tension and elastic properties, may be useful in pediatric cases. A clinical trial appears warranted.
连续环形撕囊术（CCC）目前是白内障手术中的标准操作。然而，在儿童眼中，这项技术很难实施。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。兔眼也存在类似情况。幼年白化兔的晶状体前囊非常有弹性。我们在兔眼中开发了一种CCC技术，可实现可控的圆形囊膜开口。这项技术用于对16只兔子（32只眼）的实验研究。平均撕囊直径为4.9毫米±0.9。32例中仅2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，可能对儿童病例有用。开展临床试验似乎很有必要。
