方法：2008/2009年，在中国中部一个城市郊区的白内障复明活动中，我们对所有筛查出的影响视力的白内障患者进行问卷调查，询问为何接受(或不接受)免费白内障手术等问题。将答案记录进行分析。

结果：在筛查出的892名患者中，起初只有387人(43.39%)接受免费白内障手术，最终490人(54.93%)接受手术。患者不接受白内障手术的主要原因包括：193人(21.64%)害怕手术，希望有其他治疗方式； 148人(16.59%)认为现有视力够用； 担心手术效果不如付费手术好(147，16.48%； 17人(1.91%)有其他原因。

结论：中国中部城市郊区影响实施免费白内障手术的原因主要包括：患者医学知识匮乏，周围白内障患者手术效果和指定手术医院对免费白内障手术运作形式。
