Increased Efficiency in Phacoemulsification of Hard Cataracts Using Phaco Machine With Balanced Microtip
Narrative Responses:
Purpose
To ascertain a relative efficiency in phacoemulsification of hard cataracts using the Centurion machine and Balanced MicroTip
Methods
A retrospective study of a consecutive series of 20 hard cataract cases (LOCS III NC > 4.0) operated with the Centurion system using the Balanced Tip vs. a similarly matched series of 40 cases operated with the Infiniti system using the 12 degree Partial Kelman MicroTip. Gathered data included: cumulative dissipated energy CDE, Balanced Salt Solution volume (EFU), total operation time, and complications.
Results
Total operation time average CDE and EFU increased with cataract hardness in both groups. Cases operated with the Centurion and Balanced MicroTip took significantly less time to accomplish and registered lower average CDE and EFU than those operated with the Infiniti and Partial Kelman MicroTip.
Conclusion
Surgery of hard cataracts is more efficiently accomplished with the Centurion/Balanced MicroTip configuration vs. the Infiniti/Partial Kelman.
