[Capsulorhexis technique in pediatric cataract. Presented in the rabbit model].
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.
