Cataract is the leading cause of blindness globally and surgery is the only known measure to deal with it effectively. Providing high quality cataract surgical services is critical if patients with cataract are to have their sight restored. A key focus of surgery is the outcome of the procedure. In cataract surgery this is measured predominantly, using visual acuity. Population- and hospital-based studies have revealed that the visual outcome of cataract surgery in many low and middle income settings is frequently sub-optimal, often failing to reach the recommended standards set by the World Health Organization (WHO). Another way of measuring outcome of cataract surgery is to ask patients for their views on whether surgery has changed the functioning of their eyes and their quality of life. There are different tools available to capture patient views and now, these patient-reported outcomes are becoming more widely used. This paper discusses the visual outcome of cataract surgery and frames the outcome of surgery within the context of the surgical service, suggesting that the process and outcome of care cannot be separated. It also discusses the components of patient-reported outcome tools and describes some available tools in more detail. Finally, it describes a hierarchy of challenges that need to be addressed before a high quality cataract surgical service can be achieved.
白内障是全球致盲的主要原因，手术是有效治疗该病的唯一方法。如果要恢复白内障患者的视力，则必须提供高质量的白内障手术服务。手术的一个关键重点是手术的结果。在白内障手术中，主要使用视力来衡量。基于人群和医院的研究表明，在许多低收入和中等收入国家和地区，白内障手术的视觉效果常常不理想，往往达不到世界卫生组织（WHO）设定的推荐标准。衡量白内障手术结果的另一种方法是询问患者手术是否改变了他们眼睛的功能和生活质量。有不同的工具可以用来收集患者的意见，现在，这些患者报告的结果正变得越来越广泛。本文讨论了白内障手术的视觉效果，并将手术结果置于手术服务的背景下，表明手术过程和结果是不可分割的。它还讨论了患者报告结果工具的组成部分，并更详细地描述了一些可用的工具。最后，它描述了在实现高质量白内障手术服务之前需要解决的一系列挑战。
