To describe the variables that may be utilized in the optimization of three-dimensional heads-up surgeries (3D-HUS) for achieving better ergonomics among ophthalmic surgeons.
A.
cross-sectional study was conducted at the operating room of a tertiary eye care center, equipped with an ARTEVO 800 3D surgical microscope and display monitor. The parameters noted were monitor height (MH), surgeon eye-to-floor distance (ETFD), surgeon eye-to-monitor distance (ETMD) and viewing tilt (VT) angle. The neck and eye strain of the surgeon and assistant were scored as per Borg's CR-10 scale, before and after surgeries.
Thirty (13 right, 17 left) eye surgeries were analyzed. The minimum ETMD was 51 inches (in) and the eye strain reduced with shorter ETMD (within the range 51 inches to 83 inches).The VT and ETFD were higher for right eye surgeries. The optimum MH was between 50 and 55 in. Overall, the neck strain and eye strain were in the range of 0-3 and 0-1, respectively.
The various parameters affecting the 3D image quality, neck and eye strain are chair height, VT angle, eye centration, monitor distance, laterality of the eye, and room illumination.
描述可能用于优化三维头高位手术（3D-HUS）的变量，以实现眼科医生更好的手术舒适度。
横断面研究在配备 ARTEVO 800 三维手术显微镜和显示器的三级眼科中心手术室进行。记录的参数包括监视器高度（MH）、外科医生眼离地距离（ETFD）、外科医生眼到监视器距离（ETMD）和观察倾斜（VT）角度。手术前后，根据 Borg 的 CR-10 量表对医生和助手的颈部和眼部紧张程度进行评分。
分析了 30 例（13 例右眼，17 例左眼）眼部手术。最小 ETMD 为 51 英寸（in），ETMD 越短，眼部紧张度越低（在 51 英寸至 83 英寸范围内）。右眼手术的 VT 和 ETFD 较高。最佳 MH 在 50 到 55 英寸之间。总体而言，颈部和眼部紧张程度分别在 0-3 和 0-1 之间。
影响 3D 图像质量、颈部和眼部紧张程度的因素包括座椅高度、VT 角度、眼睛居中、监视器距离、眼睛的侧别和房间照明。
