title: Power modulations in new phacoemulsification technology: improved outcomes.
abstract: OBJECTIVE
  To evaluate the clinical outcomes of new phacoemulsification technology.
  
  
  METHODS
  Oregon Eye Institute, Eugene, Oregon, USA.
  
  
  METHODS
  After optimization of surgical parameters, patients were randomly assigned to cataract extraction with 1 of 4 phacoemulsification machines using new technology available within the past 1 to 2 years. Outcomes were compared with previously published results for these same machines obtained before the advent of the new technology.
  
  
  RESULTS
  Improvements in effective phaco time, average phaco power, percentage of clear corneas, and 20/40 or better uncorrected visual acuity at the first postoperative visit were noted for most systems using new technology.
  
  
  CONCLUSIONS
  New phacoemulsification technology offers surgical advantages that translate into improved clinical outcomes.
