Ocutrx Vision Technologies LLC revealed the company’s most significant technology milestone — a next generation AR (augmented reality) headset technology for Surgery Visualization called the ORLenz, a second medical device related to their flagship Oculenz ARWear headset for Macular Degeneration. A prototype of this technology is being formally introduced at the American Academy of Ophthalmology 2019 Conference in San Francisco this October during the dedicated Retina Subspecialty Day.
The ORLenz technology will be available for surgeons and retinal specialists to utilize during procedures as an aid for delivering effective care. The ORLenz allows for a 120-degree field of view and a resolution of 60 pixels-per-degree — the highest resolution the human eye can discern (at 20/20). Ocutrx has developed its own 6DoF (6 degrees of freedom) platform for enhanced 2D and 3D “posing” of graphics and holograms from MRI’s, CT scans and other 2D/3D/4D medical imaging. The ORLenz also takes the direct feed from a digital microscope and portrays the surgery images to the surgeon in 2D or 3D. ORLenz’s MedTiles provide an overlay of vital surgery information on the 3D picture of the surgery. The ORLenz weighs about 250 grams and is wireless and tetherless, providing comfort and complete freedom of movement for the surgeon. It operates with Ocutrx’s WiDtrx wireless system, which allows video transmission without wires at multi-gigabit speeds with the same or less latency than a hard-wired connection like HDMI.
The ORLenz also has a MedTiles subsystem visual presentation, which is an overlay of vital information (text and graphs) in virtual display over the operating view. The MedTiles are virtually presented like windows or chyron-generated information visible within the AR field-of-view. For Ophthalmologic surgery, included in the MedTiles is information like IOP (intraocular pressure), Cut Rate, and Flow Rate. The MedTiles also show which "mode" a surgeon is in (vitrectomy, extrusion, dense tissue). This data is visible at the voice command of the surgeon and will run at the option of the surgeon at the bottom, side or top of his/her AR lens view. The MedTiles can also pose in a “horizon” view, where the surgeon can either dip his/her eyes below the virtual horizon to include this information as an overlay or raise his/her eyes above the horizon to only see the digital microscope view. The same works for either side viewing or top horizon. In this fashion, surgeons who dislike data distraction while conducting surgery can have the option of including the text and graph information at all times or make a slight head or eye adjustment when needed to “see” the information when they choose.
“The ORLenz provides the surgeon with the immersive experience that he/she has been trained in and will allow the surgeon’s full and undivided attention to rest on the patient, where it should be,” said Dr. Thomas A. Finley, MD, the chairman of the Ocutrx International Advisory Board. “The ORLenz is AR, and there is a difference between immersion and isolation. With VR, you are cut-off from what else is happening in the surgery room, while with the ORLenz, the experience is immersive, yet, you can still easily stay connected with the other physicians, technicians and equipment in the surgery room.”
The ORLenz for Surgery Visualization technology introduced at AAO 2019 is a prototype, with the final version set to be available in Q2 2020 when the Oculenz ARWear headset becomes available for purchase.
