Visual acuity is the measurement of an individual's ability to recognize details of an object in a space. Visual function measurements in clinical ophthalmology are limited by factors such as maximum contrast and so it might not adequately reflect the real vision conditions at that moment as well as the subjective aspects of the world perception by the patient. The objective of a successful vision-restoring surgery lies not only in gaining visual acuity lines, but also in vision quality. Therefore, refractive and cataract surgeries have the responsibility of achieving quality results. It is difficult to define quality of vision by a single parameter, and the main functional-vision tests are: contrast sensitivity, disability glare, intraocular stray light and aberrometry. In the current review the different components of the visual function are explained and the several available methods to assess the vision quality are described.
视力是衡量个体识别空间中物体细节能力的指标。临床眼科中的视觉功能测量受到诸如最大对比度等因素的限制，因此它可能无法充分反映当时的真实视力状况以及患者对世界感知的主观方面。成功的视力恢复手术的目标不仅在于提高视力行数，还在于提高视觉质量。因此，屈光手术和白内障手术有责任取得高质量的结果。很难用单一参数来定义视觉质量，主要的功能性视力测试包括：对比敏感度、失能眩光、眼内杂散光和像差测量。在本综述中，对视觉功能的不同组成部分进行了解释，并描述了几种评估视觉质量的可用方法。
