Abstract Details

Purpose:

To investigate the use of three-dimensional(3D) heads-up display(N geunity) viewing system for vitreoretinal surgery under SDI-BIOM(Stereoscopic Diagonal Inverter-Binocular Indirect Ophtalmic Microscope) and 27+ Gauge for various status.

Setting:

Nonrandomized case-control study.

Methods:

Consecutive cases to To investigate the use of three-dimensional(3D) heads-up display(N geunity) viewing system for vitreoretinal surgery under SDI-BIOM(Stereoscopic Diagonal Inverter-Binocular Indirect Ophtalmic Microscope) and 27+ Gauge for various status.have vitreoretinal surgery under various status were prospectively recruited. 3D viewing system and Twenty-five gauge vitrectomy platform and SDI-BIOM were used. Main outcomes included: luminous emittance(lux) of endoillumination pipe,surgical duration, the surgeon and residents’ preference and ergonomics. Control group patients have vitreoretinal surgery with the conventional viewing system that were recruited inclusion and exclusion criteria and underwent surgeries by the same surgeon with the same microscope and vitretomy platform.

Results:

Twenty-six patients(26 eyes; Group study) and Twenty-eight patients(28 eyes; Group control) were included; Minimum required endoillumination was significantly lower with 3D HUD(3-dimensional heads-up display)(mean 22.80%±10.2%SD) compared with SOM(a standard operating microscope)(mean 39.02%±1.72%, P<0.001). There was no significant difference in overall operative time. There were no clinically significant intraoperative complications in either group. The surgeon and residents expressed overwhelming preference with the 3D system in both groups. Improved ergonomic was rated in Group Study(4.4 0.8 vs 3.0 0.8 P<0.001). All cases without significantly statistical difference in terms of age, gender, main iagnosis, surgical duration and difficulty rating between both groups(allP<0.05)

Conclusions:

27+ Gauge vitreoretinal surgery under various status can be well finished with the 3D HUD platform. Main benefits included lower endoillumination intensity, enhanced user’s preference and surgery visualization. Reduce the repeated focusing of different magnification and save the operation time. 27+G with sutrue free technique of complete incision. It is a perfect combination in the application of vitrectomy at present.
