In this article, we report our experience with a new 3D head-mounted display system in both anterior and posterior ophthalmic surgical procedures. Threedimensional heads-up display systems have been recently described by Weinstock and Desai,1 Weinstock,2 and also Eckardt and Paulo3 as a safe, ergonomic, and well-suited method for vitreoretinal surgery. Conventional 3D surgical systems are composed of a high dynamic range camera mounted on the microscope’s optics carrier, and a 3D widescreen highdefinition (HD) LCD display located approximately at 1.5 m (5 feet) from the viewer. In these systems, the surgeon has to wear passive polarized 3D glasses to see the live image on 3D. The Sony HMS-3000MT Head Mounted Display System (Sony Electronics Inc, Tokyo, Japan) is a new generation of 3D viewing systems that provides a fullfield color video display of images from a 3D surgical camera. The system consists of the HMI-3000MT image processor unit plus the HMM-3000MT headmounted display (also referred to as helmet, Figures 1 and 2) that provides the surgeon with a personal and stereoscopic visualization of the patient’s eye. A second head-mounted display can be connected to the camera control unit for simultaneous viewing by a second user. The helmet is equipped with two organic light-emitting diode displays which offer two simultaneous HD images for the user’s left and right eyes, providing an excellent stereopsis. Experience
