PURPOSE Uncorrected refractive error is recognized as the principal cause of visual impairment in school-aged children. Although correction of refractive error is easy, safe, and effective, many children are without the necessary spectacles. Empiric research on barriers to refractive correction remains limited, precluding the formulation of effective remedial actions. The aims of this study wer...

purpose: to assess the results of combined penetrating keratoplasty and cataract extraction by extracapsular extraction versus phacoemulsification and to compare outcomes and complications. methods: in this interventional retrospective study, 76 eyes that had undergone triple surgery were included. cataract surgery was done in two different methods of extracapsular extraction and phacoemulsific...

It is estimated that 2.3 billion people worldwide have refractive error. The vast majority of these could have their sight restored by spectacles, but only 1.8 billion people have access to eye examinations and affordable correction. This leaves approximately 500 million people, mostly in developing countries (close to 1/3 are in Africa) and many children, with uncorrected error causing blindne...

There are 12.8 million children worldwide who are visually impaired due to uncorrected refractive error (URE)1, the leading cause of visual impairment among children wherever the problem has been studied.2 Half of these children live in China1, where the total number with URE may reach 100 million by 2020.3 The prevalence of myopia, the most common refractive error, is growing rapidly in childr...

BACKGROUND Uncorrected Refractive Error is one of the leading cause amblyopia that exposes children to poor school performance. It refrain them from productive working lives resulting in severe economic and social loses in their latter adulthood lives. The objective of the study was to assess the prevalence of uncorrected refractive error and its associated factors among school children in Debr...

PURPOSE To characterize refractive error, presbyopia, and spectacle correction among adults aged ≥40 years in Timor-Leste in 2010 and examine the impact of the National Spectacle Program by comparing results to those obtained 5 years earlier. METHODS A population-based, cross-sectional survey sampled 50 clusters of 45 people each. Participants with uncorrected and undercorrected refractive er...

BACKGROUND In Tanzania, the prevalence of refractive error and presbyopia have not been comprehensively assessed, limiting appropriate planning and implementation of delivery of vision care. This study sought to determine the prevalence of refractive error and presbyopia, spectacle coverage and the barriers to uptake of refractive services in people aged 15 years and older in the Kahama distric...
