Abstract
Purpose:To compare image resolution and depth between the microscope versus intracameral illumination images during 3D heads-up cataract surgery.Methods: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.Results: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).Conclusion: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.
