TrueVision Systems Continues to Refine 3D Digital Visualization Technology for Cataract Surgery

March 12, 2009

TrueVision System’s 3-dimensional, high-definition (3DHD) digital imaging system for microsurgery converts the stereoscopic optical view of surgical microscopes to a digital 3DHD image (called TrueView™), and displays it on a projection screen or monitor.

According to the company, TrueView™ delivers over twice the depth of field compared to the microscope view, and three times the resolution of standard definition, enabling surgeons to successfully perform “heads-up” microsurgery without looking into the microscope’s eyepieces. The 3DHD video recording accurately captures the surgical view. Thus, surgeons, residents and OR staff can view what traditionally only one surgeon could observe through the microscope’s binoculars.

A recent article on the Daily Sound website discussed how the TrueView™ technology is being used in cataract surgery. According to TrueView™ user Dr. Douglas Katsev, an ophthalmologist and cornea specialist, among other benefits, the visualization of surgery on a projection screen helps nurses anticipate what surgical instrument he will request next and be ready with it before he even asks, and eliminates the need for surgeons to remain hunched over a surgical microscope as they operate, thus providing ergonomic benefits. Recorded surgical footage can also be used for educational purposes.

TrueVision System programmers are currently developing software that will show surgeons where to make incisions for a variety of operations.  Cataract surgeons will be able to take a scan of a patient’s eye prior to surgery, and then during the operation, the program will display lines on the 3-D screen showing the surgeon where and how incisions should be made. Dr. Katsev commented that the guidance system will make cataract surgery more accurate.

  • there is no benefit except to help surgeons’ back and neck, and perhaps as a teaching tool. Lastly, the resolution still hasn’t reached the level of a regular microscope, so until then, it will be a novelty.
    surgeons need to take the time to adjust their position at the table to make sure they are not straining- it’s worth the 2 extra minutes.
