Usage of YouTube as an educational tool is gaining attention in academic research. To date, there has been no study on the content and quality of eye surgery videos on YouTube. The aim of this study was to analyze YouTube videos on phacoemulsification in eyes with small pupil.
We searched for the phrases "small pupil cataract surgery," "small pupil phacoemulsification," "small pupil cataract surgery complications," and "small pupil phacoemulsification complications" in January 2015. Each resulting video was evaluated by all authors, and Krippendorff's alpha was calculated to measure agreement. Videos were classified according to pupil size (small/very small) in the beginning of the surgery, and whether pupillary diameter was large enough to continue surgery safely after pupillary dilation by the surgeon in the video (safe/not safe). Methods of dilatation were also analyzed. Any stated ocular comorbidity or surgical complications were noted.
A total of 96 videos were reviewed. No mechanical intervention for pupillary dilatation was performed in 46 videos. Fifty-eight operated eyes had no stated ocular comorbidity. Ninety-five operations ended successfully without major complication. There was fair agreement between the evaluators regarding pupil sizes (Kα = 0.670) but poor agreement regarding safety (Kα = 0.337).
YouTube videos on small pupil phacoemulsification have low complication rates when compared to the literature, although no reliable mechanical dilatation methods are used in almost half of these videos. Until YouTube's place in e-learning becomes clearer, we suggest that viewers be cautious regarding small pupil phacoemulsification videos on YouTube.
YouTube作为一种教育工具在学术研究中日益受到关注。迄今为止，尚无关于YouTube上眼部手术视频内容和质量的研究。本研究的目的是分析YouTube上关于小瞳孔白内障超声乳化手术的视频。
我们在2015年1月搜索了“小瞳孔白内障手术”“小瞳孔超声乳化术”“小瞳孔白内障手术并发症”和“小瞳孔超声乳化术并发症”等短语。所有作者对每个搜索结果视频进行评估，并计算Krippendorff's alpha系数以衡量一致性。根据手术开始时瞳孔大小（小/极小）以及视频中外科医生散瞳后瞳孔直径是否足够大以安全继续手术（安全/不安全）对视频进行分类。还分析了散瞳方法。记录任何提及的眼部合并症或手术并发症。
共审查了96个视频。46个视频中未进行瞳孔扩张机械干预。58只手术眼未提及眼部合并症。95例手术成功结束，无重大并发症。评估者之间在瞳孔大小方面一致性尚可（Kα = 0.670），但在安全性方面一致性较差（Kα = 0.337）。
与文献相比，YouTube上关于小瞳孔白内障超声乳化手术的视频并发症发生率较低，尽管其中近一半视频未使用可靠的机械扩张方法。在YouTube在电子学习中的地位更加明确之前，我们建议观看者对YouTube上小瞳孔白内障超声乳化手术视频持谨慎态度。
