title: [Incidence of posterior capsule opacification in patients submitted to phacoemulsification and expandable acrylic intraocular lens implantation].
abstract: OBJECTIVE
  To evaluate prospectively the results of expandable acrylic intraocular lenses in patients submitted to phacoemulsification as regard posterior capsule opacification.
  
  
  METHODS
  The study group consisted of 830 patients, 1,200 eyes that underwent phacoemulsification from 1998 to 2002, by the same surgeon, using the same technique but with different diameters of capsulorrhexis, with expandable hydrophilic acrylic intraocular lens implantation. The mean follow-up was 2.4 years, ranging from 6 months to 4 years.
  
  
  RESULTS
  The total number of posterior capsule opacification was 54 cases.
  
  
  CONCLUSIONS
  The incidence of posterior capsule opacification was 4.6% in these patients.
