We conducted clinical and experimental studies to investigate the effects of image-sharpening algorithms and color adjustments, which enabled real-time processing of live surgical images with a delay of 0.004 s. The images were processed with image-sharpening intensities of 0%, 12.5%, 25%, and 50% during cataract surgery, vitrectomy, peeling of epiretinal membrane, and peeling of internal limiting membrane (ILM) with the Ngenuity 3D visualization system. In addition, the images obtained with a yellow filter during the ILM peeling were processed with color adjustments. Five vitreoretinal surgeons scored the clarity of the images on a 10-point scale. The images of a 1951 United States Air Force grating target placed in no fluid (control), saline, and 0.1% and 1% milk solution were evaluated. The results showed that the mean visibility score increased significantly from 5.0 ± 0.6 at 0% to 6.4 ± 0.6 at 12.5%, 7.3 ± 0.7 at 25%, and 7.5 ± 0.9 at 50% (P < 0.001). The visibility scores during ILM peeling improved significantly with color adjustments (P = 0.005). In the experimental study, the contrast of the grating targets blurred by the 0.1% and 1% milk solution increased significantly by the image-sharpening procedure. We conclude that the image-sharpening algorithms and color adjustments improved the intraoperative visibility of 3D heads-up surgery.
我们进行了临床和实验研究，以调查图像锐化算法和颜色调整的效果，这些效果使实时处理手术图像的延迟时间达到 0.004 秒。在白内障手术、玻璃体切除术、视网膜内界膜（ILM）剥除和内界膜剥除期间，使用 Ngenuity 3D 可视化系统对图像进行了 0%、12.5%、25%和 50%的图像锐化强度处理。此外，在 ILM 剥除过程中使用黄色滤光片获得的图像进行了颜色调整。五位玻璃体视网膜外科医生对 10 分制的图像清晰度进行了评分。评估了放置在无液（对照）、生理盐水、0.1%和 1%牛奶溶液中的 1951 年美国空军光栅目标的图像。结果表明，平均可见度评分从 0%时的 5.0±0.6 显著增加到 12.5%时的 6.4±0.6、25%时的 7.3±0.7 和 50%时的 7.5±0.9（P<0.001）。ILM 剥除期间的可见度评分随着颜色调整显著提高（P=0.005）。在实验研究中，通过图像锐化程序，0.1%和 1%牛奶溶液模糊的光栅目标对比度显著增加。我们得出结论，图像锐化算法和颜色调整提高了 3D 抬头手术的术中可见度。
