Abstract

Purpose: To introduce a new three-dimensional (3D) endoscope system for vitrectomy.

Subjects and methods: We report a single-center, retrospective, consecutive surgical case series of 391 eyes that underwent 25G hybrid vitrectomy. To create 3D endoscopic images, a 3D converter HD-3D-A was connected to a monocular endoscopic system.

Results: The 3D endoscope system was successfully used to perform hybrid vitrectomy. No intra- or postoperative complications related to this system were encountered in any of the cases.

Conclusion: This 3D endoscope system appears to be a valuable and promising tool for use in vitrectomy.

Keywords: 3D; endoscope; hybrid; vitrectomy; wide-angle view.

The wide-angle viewing image is integrated on the large NGENUITY 3D monitor (right) that is placed at the foot of the surgical bed. The 3D monitor for the endoscope (left) is placed 1 m to the front left of the surgeon. Abbreviation: 3D, three-dimensional.

Intraoperative processed 3D endoscope images are recorded as side-by-side stereo images. Notes: (A) Peripheral vitreous shaving around a retinal break was performed while using the endoscopic view without any scleral depression. (B) Silicone oil was removed through the cannula. Emulsified silicone oil was remarkable. Abbreviation: 3D, three-dimensional.
