Power modulations in new phacoemulsification technology: improved outcomes.
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.
