Transversal phaco, Venturi pump yield nuclear fragment control

June 1, 2011

Cataract removal using transversal phaco with a Venturi pump improved the followability of nuclear fragments and reduced chatter at the phaco tip compared with conventional longitudinal phaco with a peristatic pump.

Developments in phacoemulsification continue to evolve, according to Matteo Piovella, MD. He described the latest generation of torsional and transversal phacoemulsification and compared their effects during the annual meeting of the American Society of Cataract and Refractive Surgery.

Transversal phaco can be performed with a bent or a straight tip, while torsional phaco requires use of a bent tip. He demonstrated on a video how different ultrasound settings work in the eye.

As the technology advances, he added, the ultimate goals of phaco are shorter surgeries, fewer problems, and greater effectiveness.
