    Abstract Purpose: To report cataract surgical coverage (CSC) and effective Cataract Surgical Coverage (eCSC) from four districts in Telangana, India.
    Methods: Individuals aged ≥40 years were recruited from Adilabad, Mahbubnagar, Warangal and Khammam districts using two stage cluster sampling methodology. All participants had detailed eye examinations including visual acuity assessment using a standard Snellen chart at a distance of six meters, anterior segment examination and fundus imaging by trained professionals. CSC and eCSC were calculated for persons using a 6/12 visual acuity cut-off.
    Results: Of 12,150 individuals enumerated from four districts 11,238 (92.5%) were examined. The mean (standard deviation) age of the participants was 54.1 (±11.2) years (range: 40 to 102 years) and 54.6% (
    Conclusions: CSC and eCSC varied across the districts. A significant gap between CSC and eCSC is noted suggestive of challenges with quality of services. District-wise planning of cataract surgical services with a focus on quality care is recommended to improve coverage and contribute towards achieving the goal of universal eye health coverage in the Telangana State in India.

    Abstract Background: Uncorrected refractive error (URE) is one of the leading causes of childhood vision impairment. Increasing effective refractive error coverage (e-REC) is one of the main indicators of WHO's 2030 global eye health targets. The aim of this study is to estimate the e-REC and spectacle coverage among school children in Telangana, South India.
    Methods: School children aged 4-15 years in the study locations underwent vision screening using 6/12 tumbling E optotype by trained community eye health workers in the schools. Those failing the initial vision screening and/or found to be having eye conditions were referred to a nearby referral centre appropriately, where they underwent detailed eye examination.
    Results: A total of 774,184 children were screened in schools of which 51.49% were boys. The mean age was 9.40 ± 3.27 years. The prevalence of URE was 1.44% (95%CI:1.41-1.46) of which myopia was 1.38% (95%CI: 1.35-1.41). In multivariate analysis, the risk of myopia was higher among older children (Adj.OR: 17.04; 95%CI: 14.64-19.85), those residing in urban areas (Adj.OR:3.05, 95%CI:2.60-3.57), those with disabilities (Adj.OR:2.61, 95%CI:2.00-3.39) and among girls (Adj.OR:1.30, 95%CI:1.25-1.35) (P < 0.001). The overall e-REC was 56.97% and the spectacle coverage was 62.83%.
    Conclusion: The need for interventions to improve e-REC to achieve 2030 global eye health target is eminent among children in this region. Improving refractive services through school eye health programs could aid in accelerating this process to achieve the target. Myopia being the most common type of RE, the risk factors included increasing age, urban location, and presence of disability.

    Abstract Clinical relevance: Near Vision Impairment (NVI) is common in developing countries. A substantial proportion of NVI can be addressed by providing spectacles. Innovative eye care programmes are needed to address NVI. Population-based epidemiological studies can provide vital data to plan such eye care service delivery models.
    Background: To report the prevalence of NVI and effective Refractive Error Coverage (eREC) for near vision in West Godavari and Krishna districts in Andhra Pradesh, south India.
    Methods: A population-based cross-sectional study was carried out using a Rapid Assessment of Visual Impairment methodology. Presenting and pinhole distance visual acuity were assessed followed by near vision assessment using a N notation chart at a fixed distance of 40 cm. If the presenting near vision was worse than N8, the best corrected near visual acuity was recorded with age appropriate near vision correction. NVI was defined as presenting near vision worse than N8 among those without distance vision impairment (6/18 or better in the better eye). Effective Refractive Error Coverage for near was calculated as the proportion of individuals with an adequate correction to the total participants, including those with inadequate, adequate, and no correction for near vision.
    Results: Data of 2,228 participants aged ≥40 years were analysed. The mean age of these participants was 54.0 ± 10.4 years; 53.8% were women; 44.5% had no formal education. The prevalence of NVI was 27.1% (95% CI: 25.2-29.0%). NVI significantly associated with 70 and above age group (adjusted OR: 1.97; 95% CI: 1.45-3.70). Participants with formal education had lower odds for NVI (adjusted OR: 0.75; 95 % CI: 0.68-0.83). The eREC for near vision was 48.0%.
    Conclusion: NVI affects over a quarter of people aged ≥40 years in the West Godavari and Krishna districts of Andhra Pradesh. However, eREC is under 50% and there is scope for improving this by establishing eye care services to achieve universal eye health for all.
