title: Defining the ideal femtosecond laser capsulotomy.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  Laboratory study of capsular biomechanics and literature review of histology and published clinical results.
  
  
  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.
  
  
  CONCLUSIONS
  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.
