    Instrumentation, imaging advances make retina surgery safer

    Smaller gauge allows for smaller sphere of influence, makes tissue removal more accurate


    The faster cut rates and decreased gauge size are available in a few vitrectomy systems, i.e., VersaVit from Synergetics, the Constellation Vision System from Alcon, and the Stellaris system from Bausch + Lomb.

    Dr. Ip described the valved cannula as an important surgical aid for retinal surgeons that enhances the efficiency of vitrectomy.

    “The development of valved cannulas has been very useful and in my hands has led to more stable IOP levels and decreased rates of hypotony in cases in which an open trocar is used,” he commented.

    Upcoming technology

    Dr. Dugel sees greatly improved retinal visualization on the horizon.

    “Our visualization lags behind our mechanical abilities,” he said.

    An example of this, he pointed out, is the gradual phase out of surgical microscopes over the next 5 to 6 years.

    “I believe that we will be using digital imaging with heads-up display. That is how I currently perform all my surgeries,” he noted.
