Population-based assessment of visual acuity outcomes following cataract surgery in Australia: The National Eye Health Survey

Abstract

Aim To assess the visual outcomes of cataract surgery among a national sample of non-Indigenous and Indigenous Australians. Methods This was a population-based study of 3098 non-Indigenous Australians (50-98 years) and 1738 Indigenous Australians (40-92 years), stratified by remoteness. A poor postoperative outcome in an eye that had undergone cataract surgery was defined as presenting distance visual acuity (PVA) <6/12-6/60, and a very poor outcome was defined as PVA <6/60. Effective cataract surgery coverage (eCSC; operated cataract and a good outcome (PVA ≥6/12) as a proportion of operable plus operated cataract) was calculated. Results The sampling weight adjusted cataract surgery preval..
