    Head to head: Balanced phaco tip more efficient than Kelman tip

    Chatter minimal at all longitudinal power settings below 75%; increased with higher power

    The debate over Kelman phaco tips versus balanced phaco tips has taken a recess. A head-to-head study found the newer balanced tip is nearly 30% more efficient than the more familiar Kelman tip over the entire range of operating power, said Brian E. Zaugg, MD.

    “There have not been many objective studies comparing phaco tips,” said Dr. Zaugg, assistant professor of ophthalmology, Moran Eye Center, Salt Lake City.

    “What we have seen is that a balanced tip has more movement and an increased amount of work being applied to the cataract at a given phaco power,” he said. “This study confirms the general clinical feeling that the balanced tip is more efficient.”

    Dr. Zaugg directed an in vitro study comparing the standard Kelman tip with the newer torsional tip (OZil Intrepid Balanced tip, Alcon Laboratories). The study was conceived, led, and analyzed by Tyler D. Boulter, BS, medical student at Texas A&M University, College Park, TX.
