Transversal phaco, venturi pump yield nuclear fragment control

November 1, 2011

ECC slightly better 6 months postopcompared with longitudinal phaco and peristaltic pump

Cataract removal using transversal phaco (Whitestar Signature with Ellips Transversal Ultrasound, Abbott Medical Optics) with a Venturi pump improved the followability of nuclear fragments and reduced chatter at the phaco tip compared with conventional longitudinal phaco with a peristaltic pump. Six months postoperatively, the endothelial cell count (ECC) was only slightly decreased with transversal phaco compared with longitudinal phaco.

Developments in phacoemulsification continue to evolve, according to Dr Matteo Piovella. 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.

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