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.
