“…This is consistent with previous reports that have also shown an association between near vision and self-reported difficulty with near tasks. 1,2 However, it must be noted that a considerable portion of our population reported FNVI without presence of objective PNVI suggesting factors such as literacy (measured indirectly through education and poverty level) or other unmeasured variables may be playing a role. While similar to previous studies, 2,3,12 older age predicted higher odds of PNVI, the opposite was true for FNVI: we found lower odds of FNVI with older age.…”

Purpose Estimate prevalence of presenting near-vision impairment (PNVI) among people ≥50years in the United States (US) and examine associations with socio-demographic characteristics. Design Cross-sectional study Methods 11016 of 12781 (88.5%) US adults ≥50 years participated in the National Health and Nutrition Examination Survey (NHANES) between 1999–2008 with recorded near visual acuity. PNVI was defined as presenting near-vision worse than 20/40; functional near-vision impairment (FNVI) was defined as at least “moderate-difficulty” with either reading newsprint or near-work. Prevalence of PNVI and FNVI were estimated accounting for NHANES multistage probability sampling design. Multivariable regression models were used to determine socio-demographic characteristics associated with PNVI. Results 13.6% of participants had PNVI with 25.9% reporting concurrent FNVI. Higher odds of PNVI was associated with non-White race, older-age, male-sex, less than high-school education, lack of private health-insurance, income

“…It is common for emmetropic populations above 40 years old; eventually almost everyone will demonstrate a variable amount of near-vision impairment [1]. Projection studies suggest that by 2050 about 1.8 billion people will have presbyopia [2].…”

Evaluation of activities of daily living following pseudophakic presbyopic correction

BackgroundPseudophakic presbyopic correction is among the prevalent methods for regaining near vision capacity. The purpose of this study is to compare the impact of pseudophakic monovision correction and multifocal lens implantation on the performance in a series of activities of daily living (ADL) of presbyopic patients.MethodsAn ADL research framework (10 ADLs) was constructed and validated in a sample of patients divided into three validation groups according to their near visual acuity. Sixty-two participants that underwent mini-monovision (MoG) cataract extraction and 60 that underwent bilateral multifocal lenses implantation (MfG) populated study groups and addressed the ADLs. Binocular uncorrected distant (BdUVA) and near (BnUVA) visual acuity were associated with ADL scores and with subjective satisfaction using the VF-14 questionnaire.ResultsTest-retest reliability [all Intraclass Correlations Coefficients (ICC) >0.90] and construct validity (all p < 0.05) tests indicated sufficient psychometric performance of the ADL framework. Both study groups presented comparable mean ADL scores (p = 0.07) however, MoG patients had lower performance in demanding ADLs (p = 0.02). ADL scores demonstrated significant correlation with BnUVA (r2 = −0.67, p < 0.01) VF-14 scores (r2 = 0.53, p < 0.01).ConclusionsBoth methods provide sufficient near vision capacity for the majority of activities of daily living. However, only multifocal lens implantation can address demanding near vision tasks.Trial registrationClinicalTrials.gov Identifier: NCT02431156.

Quality of Life and Near Vision Impairment Due to Functional Presbyopia among Rural Chinese Adults

Abstract: Difficulties with activities of daily living and resulting social impediments are common due to presbyopia in this setting. Most spectacle wearers with presbyopia in rural China obtain near correction from sources that do not provide comprehensive vision care.
