title: [The application of chopping method for phacoemulsification of hard nucleus cataract].
abstract: OBJECTIVE
  The study was designed to investigate the application of chopping method for phacoemulsification of hard nucleus cataract.
  
  
  METHODS
  Modified stop and chop technique was used to emulsify the hard nucleus cataract. The degree of nuclear hardness in 80 eyes was grade IV.
  
  
  RESULTS
  Postoperatively, the visual acuity with correction was >or= 0.9 in 76.25% at 3 months. There were mild corneal edema in 8 cases, moderate corneal edema in 2 cases and posterior capsular rupture in 1 case.
  
  
  CONCLUSIONS
  The modified stop and chop technique enables the tenacious nuclear plate to rupture easily, thus the stress on the zonules and capsule can be decreased, and in the mean time the technique needs less phaco energy and time.
