The TrueVision “story” is one of digital surgery, which allows for overlays, incorporating robotics, and incorporation of preoperative diagnostics. It’s a “virtual surgical cockpit that allows you to see everything you need to during surgery,” EVP, R&D and CTO A. Burton Tipathi said. Digital ophthalmic surgery moves the surgeon away from an analogue microscope to a heads-up display; it adds navigation and connectivity and can improve patient outcomes and surgeon ergonomics. A computing platform inside the system allows for integration of various apps as well. A retrospective study found using the TrueVision 3D device resulted in a 0.35% rate of unplanned vitrectomy (n=293 eyes) compared with a rate of 1.09% (n=461 eyes) with traditional microscope oculars. Through the “IOLcompass,” incorporating digital apps, there is an “augmented reality” for anterior segment microsurgery to help align toric lenses and multifocal intraocular lenses (IOLs). The open architecture allows support to cross multiple platforms. Results on toric lens implantation have shown 87% of patients had 0.5 D or less of astigmatism postoperatively. TrueVision has partnered with Alcon to promote the NGENUITY system to vitreoretinal surgeons. A second-generation model will incorporate data onto the screen in real time, including cut rates. A subtle (but relevant) advantage of the technology is improved surgeon ergonomics. Anecdotally, Dr. Tripathi said surgeons have noted the system will add five to 10 years to their surgical careers. To date, about 1,100 systems have been sold, which is “only 4% of the potential market.” TrueVision plans to introduce the TrueScope stand-alone digital microscope; initial studies compare favorably to analogue systems. The stand-alone microscope should be available by mid-2018.
