    Phaco sleeve boosts flow, followability

    Novel design features provide protection for posterior capsule and corneal incision

     

    The sleeve also features six internal ridges, two each on opposing sides that run parallel to the shaft and one each across from each other at a position 90° to the large oval irrigation hole. The ridges prevent direct contact between the phaco tip and the sleeve where it is compressed in the incision.

    “When squeezed in the incision, a conventional sleeve comes in direct contact with the phaco tip, and the heat transferred from the tip to the sleeve can cause damage to the incision,” he said.

    The internal ridges in the new sleeve provide a barrier that prevents the sleeve from being pressed directly onto the phaco tip, he added.

    Dr. Akahoshi demonstrated the performance of the new phaco sleeve with a video involving an eye with a dense, grade 4+ nuclear cataract removed with prechopping and a combination of torsional and longitudinal ultrasound.

    “Most cataract cases can be done with cumulative dissipated energy less than 10, but the CDE for the case was almost 40,” he said. “Using a conventional phaco sleeve, severe damage to the incision would be likely.”
