To compare image resolution and depth between the microscope versus intracameral illumination images during 3D heads-up cataract surgery.
We collected 25 consecutive patients who had cataract surgery using the 3D viewing system. Based on bright, contrast, visibility, and color balance, the digital images (RGB color and three monochromes) extracted at the same point of the procedures were compared between the two illuminations.
Contrast values of green and blue channels except for red channel and visibility values of all three channels were higher in the intracameral illumination images than in the microscope images (P < 0.001, t-test). Color balance values of both green/red and blue/red were higher in the intracameral illumination images than in the microscope images (P < 0.001, t-test).
The digital images in the digitally assisted cataract surgery were enhanced by using the intracameral illumination. Considering the contrast and color balance in the 3D cataract surgery, the intracameral illumination may be better than the microscope illumination.
比较 3D 抬头白内障手术中显微镜与眼内照明图像的分辨率和景深。
我们收集了 25 例连续接受 3D 观察系统白内障手术的患者。根据亮度、对比度、可视度和色彩平衡，比较了两种照明条件下同一手术点提取的数字图像（RGB 彩色和三种单色）。
除红色通道外，绿色和蓝色通道的对比度值和所有三个通道的可视度值在眼内照明图像中均高于显微镜图像（P < 0.001，t 检验）。绿色/红色和蓝色/红色的色彩平衡值在眼内照明图像中均高于显微镜图像（P < 0.001，t 检验）。
数字化辅助白内障手术中的数字图像通过眼内照明得到增强。考虑到 3D 白内障手术中的对比度和色彩平衡，眼内照明可能优于显微镜照明。
