Correcting refractive error in low income countries.

More than meets the eye in correcting refractive error in low income countries.

Optical products for refractive error and low vision

Large numbers of people, mostly in lowand middle-income countries, continue to be blind or visually impaired due to uncorrected refractive error or cannot function because they lack access to appropriate low vision aids. Numerous challenges have been cited as the reason for the lack of efficient refractive error and low vision services. These include a lack of appropriate human resources, inade...

Two strategies for correcting refractive errors in school students in Tanzania: randomised comparison, with implications for screening programmes.

PURPOSE To compare whether free spectacles or only a prescription for spectacles influences wearing rates among Tanzanian students with un/undercorrected refractive error (RE). METHODS DESIGN Cluster randomised trial. SETTING 37 secondary schools in Dar es Salaam, Tanzania. PARTICIPANTS Distance visual acuity was measured in 6,904 year-1 students (90.2% response rate; median age 14 yea...

Racial disparities in uncorrected and undercorrected refractive error in the United States.

PURPOSE To identify risk factors for inadequately corrected refractive error in the United States. METHODS This cross-sectional study included 12,758 participants 12 years of age and older from the 2005 to 2008 National Health and Nutrition Examination Survey. The primary outcome was the proportion of individuals with inadequate refractive correction for whom refractive correction would resul...

Global cost of correcting vision impairment from uncorrected refractive error.

OBJECTIVE To estimate the global cost of establishing and operating the educational and refractive care facilities required to provide care to all individuals who currently have vision impairment resulting from uncorrected refractive error (URE). METHODS The global cost of correcting URE was estimated using data on the population, the prevalence of URE and the number of existing refractive ca...
