Key Highlights:

  •  A significant proportion of the global population is visually impaired solely because of uncorrected refractive error (URE). Considering its potential impact, URE has become one of the priorities of the VISION 2020 programme to eradicate avoidable blindness.
  • The purpose of this study was to summarise relevant literature investigating the impact of URE on adults and the impact of correcting refractive error in this population.
  • A systematic search of 13 data bases and the reference lists of retrieved studies was conducted using the standard methodology for systematic reviews as described in the PRISMA statement. The Consolidated Standards of Reporting Trials (CONSORT) Guidelines and the Critical Appraisal Skills Programme (CASP) tools were used to assess the quality of the full text articles that were initially considered as meeting the systematic review inclusion criteria. Descriptive statistics was used to analyse the data.
  • The initial search retrieved 663 studies and 23 met the set inclusion criteria. Of the 23 studies selected for inclusion in the review, two were randomised control trials (RCTs), one was a cohort study, two had a case-control design, and 18 studies employed a cross-sectional design.
