Abstract：
BACKGROUND: Informed consent constitutes an important aspect of eye care. However, patients often experience difficulties understanding and retaining information presented to them during consultations. This study investigates the efficacy of pictorial aids in supplementing preoperative counselling of patients undergoing cataract surgery.
METHODS: Patients attending routine pre-cataract surgery counselling were randomized to receive either a standard verbal consultation (control) or a verbal consultation with a digitalized pictorial aid illustrating key surgical steps (intervention). Patients were assessed after the consultation on their knowledge, satisfaction, anxiety and preparedness using an anonymous questionnaire.
RESULTS: Seventy-six patients were recruited and randomized into the control and intervention groups. The intervention group attained better Knowledge Scores (control: 5 [2-6] vs. intervention: 6 [6]), and more patients \"strongly agreed\" that they were more prepared (control: 78.9% vs. intervention: 97.4%, P=0.028). A higher proportion of patients in the control group either \"disagreed\" or \"neither disagree nor agreed (neutral)\" that they were less worried (control: 15.8% vs. intervention: 0.0%, Fisher\'s Exact Test P=0.025). Although the consultation duration was shorter in the intervention group (21±4mins vs. 27±6mins, P<0.001), the use of digital pictorial aids during consultation resulted in more effective counselling with increased patient knowledge, easier decision-making process and reduced patient anxiety.
CONCLUSIONS: Pictorial aids add to the repository of tools available to eye-care practitioners and are low-cost, easy to implement, and can effectively augment existing preoperative counselling processes to ensure accurate and effective preoperative counselling of patients.

摘要：
背景：知情同意是眼部护理的一个重要方面。然而,患者在咨询过程中经常遇到困难理解和保留提供给他们的信息。这项研究调查了绘画辅助工具在补充白内障手术患者术前咨询中的功效。
方法：接受常规白内障手术前咨询的患者被随机分配接受标准的口头咨询（对照）或带有说明关键手术步骤（干预）的数字化图片辅助工具的口头咨询。患者在咨询他们的知识后进行评估，满意,焦虑和准备使用匿名问卷。
结果：纳入76例患者，随机分为对照组和干预组。干预组获得了更好的知识分数(对照：5[2-6]vs.干预：6[6])，更多的患者“强烈同意”他们更有准备(对照：78.9%vs.干预：97.4%，P=0.028)。对照组中“不同意”或“既不同意也不同意（中立）”的患者比例较高，他们不太担心（对照组：15.8％vs.干预：0.0%，Fisher精确检验P=0.025)。尽管干预组的咨询持续时间较短（21±4分钟vs.27±6分钟,P<0.001)，在咨询过程中使用数字绘画辅助工具可提高患者知识的更有效咨询，更容易的决策过程和减少患者的焦虑。
结论：图片辅助工具增加了眼睛保健从业人员可用的工具库，并且成本低，易于实现，并能有效加强现有的术前咨询流程，确保对患者进行准确有效的术前咨询。
