Power modulations in new phacoemulsification technology: improved outcomes.

PURPOSE To evaluate the clinical outcomes of new phacoemulsification technology. SETTING 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. CONCLUSION New phacoemulsification technology offers surgical advantages that translate into improved clinical outcomes.
