    Background: To compare the content and quality of 3D YouTube videos with 2Ds as additional educational tools for phacoemulsification surgery. Methods: This cross-sectional study included 2D and side-by-side 3D phacoemulsification videos found on YouTube by searching for “phacoemulsification,” “phaco,” and “cataract.” Data was collected on video length (min), time since upload (days), number of views, likes, dislikes, cataract type, chop technique, and visualization system. Video popularity and interaction were calculated by video power index, interaction index, and viewing rate. Two senior ophthalmologists (SOs) and two ophthalmology residents (ORs) evaluated videos using the DISCERN, global quality score (GQS), and usefulness scoring systems. Inter-rater reliability was assessed using intra-class correlation coefficient (ICC). Results: A total of 457 videos were screened, with 85 in 2D and 85 in 3D deemed appropriate for analysis. 2D videos received significantly more views, likes, dislikes, days since upload, video power index, and viewing rate than 3Ds (p < 0.001). Video length and interaction index in 3D videos were significantly greater than in 2Ds (p < 0.001). All video scoring systems revealed that 3D videos outperformed 2Ds in ORs (p < 0.05). ICC confirmed good inter-rater reliability agreement even at the lowest value (SOs: 0.924, 95% CI, 0.910–0.937; ORs: 0.892, 95% CI, 0.878–0.908). Conclusions: 3D YouTube videos as additional educational tools could help not only SOs but also ORs fully comprehend the breadth and depth of ocular surgeries, particularly phacoemulsification, by improving depth perception. They can also be used to review previously learned procedures, observe new ones, and recall old ones.
