3-D visualization system enhances view of microsurgical techniques

A 3-D high-definition visualization system designed specifically for microsurgery can assist ophthalmologists in clinical practice and teaching, according to one glaucoma specialist.
The TrueVision 3D Surgical Visualization System is a three-part stereoscopic device that provides a real-time view of the operative field. TrueVision 3D can be used during various procedures, such as spine, vascular, and ear, nose and throat surgery. However, as ophthalmologists begin to incorporate the system into their surgical routines, they are quickly discovering its value.
Richard A. Lewis, MD, an OSN Glaucoma Board Member, is one of the first glaucoma specialists in the country to use the TrueVision system. Although not widely used in the glaucoma field, TrueVision has been used in other subspecialties, such as cataract and corneal surgery, for about 2 years, according to Dr. Lewis.
However, he said that all eye surgeons could benefit from the system because it can be used anytime a surgical microscope is required. Moreover, the True-Vision Image Capture Module, which attaches to the eyepiece, is compatible with most microscopes and maintains the normal functions of the device.
Whereas conventional microsurgery allows only the operating surgeon to observe the stereoscopic field of view, TrueVision 3D can present the images to an entire operating room or exam room.
Software converts the microscope’s optical view into a digital 3-D image that is then projected onto a flat panel liquid crystal display screen. The panels range from 24 inches to 46 inches and can be mounted on the wall, from the ceiling or on a boom arm, depending on the surgeon’s needs.
In addition, the system can display streaming 3-D surgical video, as well as record and edit more than 2 hours of video for use during future medical courses, conferences and lectures.
Dr. Lewis, who helped introduce TrueVision 3D at the 2010 American Academy of Ophthalmology meeting, said these comprehensive features are what make the system so useful for teaching both students and surgeons.
“The system presents the image to you in a way that you are not used to seeing it, so you can see more detail, the good and the bad,” Dr. Lewis told Ocular Surgery News in an interview.
TrueVision 3D can be especially helpful for surgeons who are teaching in large lecture halls because it allows students to more accurately visualize ocular pathology, he said. For the same reason, Dr. Lewis has used TrueVision 3D to review old techniques and teach new skills to his colleagues.
In addition to offering advanced image clarity, TrueVision 3D provides surgeons with the ergonomic support necessary for lengthy procedures.
According to Dr. Lewis, neurosurgeons are the most widespread users of the system because, like ophthalmologists, they perform complex procedures within a very limited area. With TrueVision 3D, surgeons do not have to sacrifice comfort in order to maintain accuracy; the system allows them to operate in an upright position, rather than hunched over a microscope.
“It has real advantages for those with back and neck problems,” Dr. Lewis said. “If you use the system in its full capacity, you can watch the flat panel screen instead of being forced to sit at the oculars.”
However, for surgeons who prefer to have access to the eyepiece during surgery, a stereo bridge can be attached to the microscope in order to work with TrueVision 3D and the eyepiece simultaneously.
Although 3-D technology emerged in ophthalmology through advancements in optical coherence tomography and ultrasound imaging, TrueVision 3D will give surgeons the opportunity to expand the technology beyond just diagnostics. – by Courtney Preston
