Impact of cataract surgery on visual acuity and subjective functional outcomes: A population-based study in Sweden

PurposeTo determine the prevalence of amblyopia and its association with refraction in Chinese preschool children.MethodsThe Yuhuatai Pediatric Eye Disease Study, a cross-sectional, population-based study, was conducted in children aged 36–48 months in Yuhuatai District, Nanjing, China, in 2015. Visual acuity was measured in 1695 eligible children.ResultsOf the 1695 subjects, manifested amblyopia was detected in 25 children (1.47%, 95% CI 0.90% to 2.05%), including 11 and 14 with bilateral and unilateral amblyopia, respectively. Amblyopia prevalence did not differ by gender (p=0.77). Significant refractive errors were found in 22 (88.0%) of children with amblyopia, and strabismus was found in 6 (24.0%) children with amblyopia. In multivariate analysis, amblyopia was significantly associated with hyperopia (≥+2.00 dioptres (D); OR 8.81, 95% CI 3.27 to 23.69, p<0.0001), astigmatism (≥2.00 D; OR 17.90, 95% CI 6.78 to 47.21, p<0.0001) and anisometropia (≥2.00 D; OR 5.87, 95% CI 1.52 to 22.77, p<0.05).ConclusionsThe prevalence of amblyopia in children 36–48 months old in Eastern China was 1.47%. The refractive error is a major risk factor for amblyopia.

AimTo assess the visual outcomes of cataract surgery among a national sample of non-Indigenous and Indigenous Australians.MethodsThis 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.ResultsThe sampling weight adjusted cataract surgery prevalence was 19.8% (95% CI 17.9 to 22.0) in non-Indigenous Australians and 8.2% (95% CI 6.0 to 9.6) in Indigenous Australians. Among the non-Indigenous population, poor and very poor PVA outcomes were present in 18.1% and 1.9% of eyes, respectively. For Indigenous Australians, these values were 27.8% and 6.3%, respectively. The main causes of poor vision were refractive error (non-Indigenous=41.8%; Indigenous=41.9%) and coincident disease (non-Indigenous=43.3%; Indigenous=40.3%). The eCSC rates in the non-Indigenous and Indigenous populations were 88.5% (95% CI 85.2 to 91.2) and 51.6% (95% CI 42.4 to 60.7), respectively.ConclusionApproximately half of eyes with a poor visual outcome postcataract surgery could be readily avoided through the appropriate refractive correction. The finding of a lower eCSC rate among Indigenous Australians suggests that improvements in access and quality of cataract services may be warranted in order to reduce cataract-related vision loss in the Indigenous population.
