For surgeons, the attention to detail in new technologies being offered today is allowing them to perform safer, more efficient procedures.

Advances in the technologies used by retina surgeons are moving ahead at a rapid-fire pace. Dozens of new devices that are smaller (and sometimes larger), shorter, brighter, and lighter have recently become commercially available with the hope of making surgeries easier and more efficient. David R. Chow, MD, FRCSC, detailed several new tools for physicians to consider adding to their practices.
Dr. Chow is assistant professor of ophthalmology, University of Toronto, St. Michaels Hospital, Toronto Retina Institute, North York, Canada.
Bausch + Lomb has introduced a bi-blade dual-port vitrectomy cutter with an innovative dual-blade design that features a cut rate of 15,000 cuts/minute and is available in three gauges: 23, 25, and 27. The instrument can increase balanced saline flow by 230% and increase vitreous flow by 180%.
Bausch + Lomb also has developed the Vitesse Hypersonic Vitrectomy probe that boasts a new cutting concept, in that the needle is mounted to a piezoelectric ultrasound transducer that vibrates harmonically resulting in a cut rate greater than 1 million cpm. This instrument has been used in more than 200 procedures worldwide with a wide range of vitreoretinal pathologies. It can effectively remove vitreous, lens material, membranes, and silicone oil.
Alcon is offering the Hypervit Dual-Blade Vitrectomy Probe that is capable of 20,000 cuts/minute. This instrument has a beveled tip design, which lets it move up to 50% closer to the retinal surface; it is available in 25- and 27-gauge. A new prototype probe, the multiport vitrectomy cutter features an outer sleeve that can be rotated to expose three ports.
“This exposure of the additional ports facilitates higher flow rates,” Dr. Chow said.
