We define the ideal anterior capsulotomy through consideration of capsular histology and biomechanics. Desirable qualities include preventing posterior capsular opacification (PCO), maintaining effective lens position (ELP) and optimising capsular strength.
Laboratory study of capsular biomechanics and literature review of histology and published clinical results.
Parameters of ideal capsulotomy construction include complete overlap of the intraocular lens to prevent PCO, centration on the clinical approximation of the optical axis of the lens to ensure concentricity with the capsule equator, and maximal capsular thickness at the capsulotomy edge to maintain integrity.
Constructing the capsulotomy centred on the clinical approximation of the optical axis of the lens with diameter 5.25 mm optimises prevention of PCO, consistency of ELP and capsular strength.
通过考虑囊膜组织学和生物力学来定义理想的前囊切开术。理想的特性包括预防后囊膜混浊（PCO）、维持有效的晶状体位置（ELP）以及优化囊膜强度。
囊膜生物力学的实验室研究以及组织学和已发表临床结果的文献综述。
理想的囊切开术构建参数包括人工晶状体完全重叠以预防PCO、以晶状体光轴的临床近似位置为中心以确保与囊膜赤道同心，以及在囊切开边缘处保持最大囊膜厚度以维持完整性。
构建直径为5.25 mm、以晶状体光轴的临床近似位置为中心的囊切开术，可优化PCO的预防、ELP的一致性和囊膜强度。
