    New instruments, devices improve safety and speed in vitreoretinal surgery

    Features provide surgeons with advancements for their practices, use in operating room

    Take-home message: David R. Chow, MD, provides an overview of new technological advancements for the vitreoretinal surgeon.

    Toronto—Several product launches in recent months are expanding the vitreoretinal surgical armamentarium. These include new vitrectomy platforms, probes, chandeliers, cannulas, surgical lenses, forceps, and loops. David R. Chow, MD, highlights some of these many innovations in this technology overview.

    The EVA PhacoVitrectomy System (DORC) has advanced features, the backbone of which, according to Dr. Chow, is its two-dimensional cutter. The high-speed vitrector probe is capable of 16,000 cuts/minute. The cutter comes with an optional handle extension and has a double cut and double aspiration with each duty cycle—due to its unique inner sleeve. This system recently received FDA 510(k) clearance.

    “In the laboratory, in balanced saline solution and artificial vitreous, the cutter creates aspirational flow rates that remain constant and are independent of the cut rate, due to its 92% duty cycle,” said Dr. Chow, assistant professor of ophthalmology, University of Toronto, St. Michael’s Hospital, Toronto.

    He explained the increased safety associated with this system as a result of the reduced traction on the surrounding tissue with double cuts and no surges in turbulence.

    Constellation CR4 Software upgrade (Alcon) is another recent product to enter the market. The software has a number of phaco and vitreoretinal enhancements.

    “The software upgrade supports a 10,000 cut/minute vitrector probe (Advanced Ultravit Vitrectomy Probe), the Autosert IOL injector, Ozil IP functionality for cataract surgery, and various usability enhancements,” Dr. Chow said.

    The Advanced Ultravit Vitrectomy Probe, in addition to its high-cut rate, has a beveled tip that allows the instrument to come into closer proximity to the retina.

    The latest iteration of the Versavit 2.0 Platform (Synergetics) offers some new surgical features for surgeons including reflux, increased vacuum levels up to 600 mm Hg, and a better port entry system.
