We conducted a prospective study of 56 patients aged 70 to 79 years undergoing cataract surgery, in order to determine the impact of surgery on subjective and objective measurements of visual ability. In 46 cases we could obtain all necessary data. Binocular visual acuity, near vision and contrast sensitivity improved due to surgery. Self-assessed ability to perform visually related tasks was examined in form of a questionnaire. The results show that there was no simple relationship between objective measurements and perceived visual ability. An impairment in preoperative visual acuity cannot be related to a specific loss of visual ability. In order to increase the quality of cataract surgery more subtly, subjective aspects of vision must be taken into consideration when operation is decided upon and in the evaluation of the results.
我们对56例年龄在70至79岁之间接受白内障手术的患者进行了一项前瞻性研究，以确定手术对视觉能力主观和客观测量的影响。在46例病例中，我们能够获得所有必要数据。手术使双眼视力、近视力和对比敏感度得到改善。通过问卷调查的形式检查了自我评估的视觉相关任务执行能力。结果表明，客观测量与感知视觉能力之间不存在简单的关系。术前视力受损与特定的视觉能力丧失无关。为了更精细地提高白内障手术质量，在决定手术和评估结果时必须考虑视觉的主观方面。
