متن کاملGlobal 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...
