For this controlled trial, 463 patients were randomly assigned to two groups. The control group received cataract information leaflets and the study group received both leaflets and an educational video compact disc (VCD). Eighty percent of the subjects were more than 60 years old, and 86% were Chinese. Both groups showed significant knowledge acquisition and were marginally less fearful and nervous than before the study began. Between groups, however, there was no significant difference in knowledge and anxiety level. The subjects' preferences of information formats were: verbal (spoken) 54%, VCD 47%, and printed 36%.
在这项对照试验中，463名患者被随机分为两组。对照组收到白内障宣传手册，研究组则同时收到宣传手册和一张教育视频光盘（VCD）。80%的受试者年龄超过60岁，86%为中国人。两组患者均显示出知识水平显著提高，且比研究开始前略微不那么恐惧和紧张。然而，两组之间在知识水平和焦虑程度上没有显著差异。受试者对信息形式的偏好分别为：口头（讲解）54%、VCD 47%、印刷品36%。
