Heads-up 3-D Visualization in Complex Vitreoretinal Surgery

The first use of heads-up 3-D technology was reported by Claus Eckardt, MD.1 Since that time, interest in the use of heads-up 3-D visualization has grown, and the technology has improved. The basic setup of the 3-D heads up display system has been described previously.2 In brief, two cameras affixed to an operating microscope send signals to a central processor, which transmits an image onto a wide-screen high-definition monitor. Surgeons wear polarized glasses to appreciate the three-dimensionality of the image on a 2-D surface. Often-cited benefits of using a 3-D heads-up display include improved ergonomics, increased depth of field, wider field of view, the possibility to overlay other data such as images from optical coherence tomography and fluorescein angiography during surgery, and the ability to digitally amplify images.2,3-6 In this article we explain how heads-up 3D visualization, specifically with the Ngenuity 3D Visualization System (Alcon), can be used to perform complex surgical procedures.
