TrueVision Releases New Computer-Guided Surgery System for Cataract Surgery

TrueVision 3D Surgical, the world’s leader in 3D visualization and guidance applications for microsurgery, announced the release of the TrueGuide Computer-Guided Surgery System. TrueGuide provides digital guidance for astigmatism correction and advanced lens placement during cataract surgery.

TrueVision presented TrueGuide at the 117th Annual Meeting of the American Academy of Ophthalmology on Nov. 16-19.

Cataract surgery is the most commonly performed procedure in the world. In the United States alone, nearly 3 million procedures are performed each year. Of those 3 million procedures, more than 70 percent of patients will have astigmatism greater than 0.5 diopters, which can require the use of corrective eyewear post-operatively when left untreated.

Astigmatism can be corrected during cataract surgery using different methods, including the use of toric lens implants and/or performing corrective incisions in the eye (AK/LRIs). The efficacy of these options is directly related to alignment and placement.

TrueGuide is the first and only computer-guided surgery system with dynamic optimization, which matches patient conditions to available treatment options specific to surgeon parameters and tendencies in real-time during surgery. This guidance assists surgeons in targeting the lowest residual astigmatism based on multiple variables with toric IOL alignment, limbal relaxing incision, incision placement and intraocular lens centration.

TrueGuide integrates with multiple diagnostic devices through the TrueCapture software for accurate pre-operative analysis and surgical planning. TrueGuide software will bring optimal patient efficiency to cataract surgical practices, as well as provide precise data for use in the TrueVision® computer-guidance surgical applications.

“We see TrueGuide as a key component of premium practices wishing to offer state of the art capabilities to their patients seeking cataract surgery, along with the near-term potential to integrate with new and existing complementary surgery technologies,” said Forrest Fleming, CEO of TrueVision. “Compatibility with any surgical microscope is a key aspect of this broad appeal.”

“I am an early adopter of TrueGuide computer guidance for my practice,” said Jonathon Solomon, M.D., of Solomon Eye Physicians & Surgeons. “I use TrueGuide for centration of multifocal lenses and toric lens alignment. The preliminary results are outstanding and I am excited to use TrueGuide as a standard of care for my practice.”

“I’ve been working with TrueVision since it was only a heads-up 3D visualization system. They were also the first to introduce computer-guided surgery to the market,” said James Katz, M.D., of The Midwest Center for Sight. “TrueVision is the pioneer of computer-guided ophthalmic surgery and the new features and capabilities of TrueGuide bring more precision to many key steps of advanced cataract surgery.”
