“…The construct validity of the VND-Q was supported in the present study, where respondents with poorer selfreported general vision in low-light and with glare had more vision-related night driving difficulties. Notably, respondents who self-reported bilateral eye conditions had more difficulties, which provides additional support of construct validity of the VND-Q, given that conditions such as glaucoma, 61 AMD 24,62 and cataract 63,64 are known to impair mesopic vision and increase glare sensitivity. However, the majority of respondents did not self-report any eye disease (69%), therefore the ability to generalise these results for glaucoma, AMD and cataract populations is limited.…”

“…Pioneering studies has demonstrated that PBMs can be reliable and valid methods in assessing real-life visual ability. [13][14][15][16][17][18][19][20][21][22][23] Owing to its significance in visual hierarchy, PBMs of visual function is becoming an important part of researches on the real-life effects of visual diseases.…”

“…More recently there is a coming up of trend in developing a method for evaluation of functional vision-performance-based measures (PBMs) of visual function. [13][14][15][16][17][18][19][20][21][22][23] It involves presenting patients with commonly encountered tasks of daily life in a standardized format and getting a grade in accordance with their visual ability to complete the tasks.

Purpose Real-Life Vision Test (RLVT) is a newly developed performance-based measures of functional vision. This present study is designed to determine whether it could be a meaningful assessment for cataract surgery outcomes evaluation. Patients and methods Age-related cataract patients (56) who scheduled for bilateral cataract surgery and 44 age-matched controls were evaluated by four types of measurements: (1) demographic, medical, cognitive and depressive evaluation, and the reaction time testing; (2) clinical measures (visual acuity, contrast sensitivity, stereopsis, and color perception); (3) the 25-item National Eye Institute's Visual Functioning Questionnaire (NEI-VFQ); (4) the RLVT. Spearman's coefficients and multiple regression analysis were conducted to investigate the relationship among RLVT, clinical measures, and self-report assessment of visual function. Results The results of RLVT, clinical measures, and NEI-VFQ total scores were improved significantly after cataract surgery. There were no differences between control subjects and post-surgery patients with respect to NEI-VFQ-25 total scores, self-rating depression scale scores and three tasks of RLVT. Change of RLVT was significantly associated with the change of clinical measures in the cataract group. Multiple regression analysis demonstrated that change of distance, intermediate, and near visual acuity, and binocular contrast sensitivity were significant predictors of improvements of RLVT.Conclusions Cataract surgery could improve real-world visual ability effectively for cataract patients. Our study highlights the potential usefulness of RLVT as an adjunct to the current outcomes evaluation system for cataract surgery. The use of RLVT combined with clinical and self-survey methods may be the comprehensive strategy to manifest the impact of cataract surgery on patients' overall vision-related quality of life.

“…2,10,17 Based on the inherent limitations of clinical tests and self-report questionnaires, more recently there has been an upcoming interest in developing a complementary method for evaluation and outcome measures of visual function-the performancebased measures (PBMs) of visual function. 4,10,13,[18][19][20][21][22][23][24][25][26][27] Vision-specific PBMs take on actual performance of vision-related tasks. It involves presenting patients with commonly encountered tasks of daily life in a standardized format and getting a grade in accordance to their visual ability to complete the tests.…”

Purpose (1) To describe and validate a newly developed, timed performance-based measures of functional vision-the real-life vision test (RLVT). (2) To determine how RLVT relates to clinical measures and selfreport assessment of visual function and the complex interactions among visual impairment, psychosocial status, and demographic factors. Methods A total of 64 patients with age-related cataract and 45 age-matched controls were evaluated by four types of measurements: (1) demographic, medical, cognitive, and depressive evaluation and the reaction time (RT) testing; (2) clinical measures (visual acuity, contrast sensitivity, stereopsis, and the color perception); (3) the 25-item National Eye Institute's Visual Functioning Questionnaire; and (4) the RLVT. Spearman's coefficients, partial correlation, and multiple regression analysis were conducted to determine the relationship among RLVT, clinical measures, and selfreport assessment of visual function while controlling for confounders. Results Control subjects performed RLVT significantly better than the cataract patients. RLVT correlated well with both clinical and self-report assessments of visual function. All subscales of RLVT remained highly associated with most of the clinical measures, even after adjusting for age, years of education, depression, cognitive status, and the RT. Distance, intermediate and near visual acuity, and binocular contrast sensitivity were significant predictors of the RLVT performances. Conclusions Given the strong relationship among RLVT, clinical measures, and the self-report assessments, our results highlight the potential usefulness of RLVT for assessing the functional vision of cataract patients. RLVT may provide information not obtainable from clinical measures or surveys and therefore it is essential to be incorporated into future ophthalmological practice.
