提出了一种基于自我评估的视功能测量指数，并对其进行了临床和统计学评价。结构效度和信度均达到了设计要求。“视觉功能指数”已被应用于一组白内障患者。当然，在双眼白内障患者中，视觉功能与最佳眼睛的视力相关，但这种相关性并不是直接的。因此，对于视觉损伤的评估，必须同时测量视觉敏锐度和视觉功能。将该指数应用于一组单晶状体白内障患者，表明即使在第一次白内障摘除手术后，视功能也有很好的改善。理想的情况是，白内障手术应该在整个视觉功能和社会融合严重受损之前进行。在此基础上，这项研究中约20%的患者应该在更早的阶段进行手术，这表明需要额外的手术能力。
An Index for measuring Visual Functioning on the basis of self‐assessment is presented and evaluated clinically and statistically. The construct validity and the reliability are shown to be sufficient. The ‘Visual Functioning Index’ has been applied to a group of cataract patients. In bilateral cataract patients visual functioning is, of course, correlated to visual acuity in the best eye, but this correlation is not straight forward. So, for the assessment of visual impairment both visual acuity and visual functioning must be measured. Application of the Index to a group of monaphakic cataract patients indicates a good improvement of visual function obtained even by first cataract extraction. Ideally cataract surgery should be performed before the total visual functioning and social integration is severely damaged. On this basis about 20% of the patients in this study should have been operated at an earlier stage, which among other things suggests a need for additional surgical capacity.
