Needs and views on eye health and women's empowerment and theory of change map: implication on the development of a women-targeted eyecare programme for older Zanzibari craftswomen.

OBJECTIVES: To assess needs and views regarding eye health and empowerment from craftswomen's perspectives to develop a theory of change (ToC) for a women-targeted eyecare programme. MATERIAL AND METHODS: Eighteen stakeholders participated in a 2-day consultation workshop in Zanzibar. The composition was (1) 15 women and 3 men; (2) Unguja (n=8), Pemba (n=6) and Tanzania mainland (n=4) and (3) craftswomen (n=14) and governmental stakeholders (n=4). Thematic analysis determined the craftswomen's needs and views regarding eye health and empowerment and subsequently inputs, activities, outputs, outcomes and impact to develop the programme's initial ToC. In refining the initial ToC, we used insights from a qualitative study suggesting that improved near vision is perceived by craftswomen as a potential source of empowerment across economic, psychological, social, political and educational dimensions. RESULTS: The eye conditions experienced by the craftswomen were eye irritation caused by foreign bodies, the need for near spectacles and other eye morbidities. They were advised by the cooperatives to visit eye health centres for treatment. The main barriers to accessing services were inaccessibility and unaffordability of eye services and a lack of eye health knowledge and practices. Nineteen subthemes on women empowerment (economic n=4, social n=4, psychological n=6, education n=2 and political n=3) were obtained. We created a ToC on how investing in improving craftswomen near vision could achieve empowerment. CONCLUSION: The participants provided insights into their needs and how they would like the eyecare programme to be implemented and how they see they could be empowered in the process.

Contextual factors affecting integration of eye health into school health programme in Zanzibar: a qualitative health system research.

BACKGROUND: Short-term school eye health programmes supported by external funders have sustainability issues. This study aimed to understand the contextual factors affecting integrating eye health into the school health programme. METHODS: We elicited responses from 83 respondents, purposefully selected from the Ministry of Health (n = 7), Ministry of Education and Vocational Training (n = 7), hospitals/eye centres (n = 5), master trainers (4) and schools (n = 60) who participated in in-depth interviews. Their responses were analysed and grouped into contextual factors according to the WHO Consolidated Framework for Implementation Research: stakeholders/political, institutional, physical, cultural, delivery system and others. Themes were then generated, and quotations were presented to illustrate the findings. RESULTS: The six contextual factors affecting the integration of eye health into the school eye health programme were i) Stakeholders/political (Good ministry coordination, defined departmental roles and resource mobilisation from multiple stakeholders; Good stakeholder synergies and address current gaps); ii) Institutional (Institutional coordination and adequate clinic space; Securing human and financial resources; Strategic advocacy for institutional resources); iii) Physical (Long travel distance to service points); vi) Cultural (low eye health awareness among parents, teachers and children); iv) Delivery system (Practical approach to increase screening coverage using teachers as screeners; Balance teachers' workload, increase screening sensitivity and follow up and; v) Others (Comprehensive training material and effective training delivery; Improved curriculum, teacher selection and supervision and incentives). CONCLUSION: Integrated school eye health delivery is generally well-received by stakeholders in Zanzibar, with the caveat that investment is required to address the six contextual factors identified in the study.

Subjective Wellbeing, Work Performance and Lived Experience of Zanzibari Women Entrepreneurs with Uncorrected Functional Presbyopia: A Pre-Post Mixed-Methods Study.

PURPOSE: Uncorrected presbyopia has been shown to reduce Zanzibari women's quality of life. In this mixed-methods study, we examined the subjective wellbeing and self-reported work performance among older women entrepreneurs with functional presbyopia before and shortly after correction, and how poor vision at close distance affected their daily lives. METHODS: Women entrepreneurs underwent eye examination to identify those with uncorrected functional presbyopia. Their subjective wellbeing and work performance were both measured in Cantril's ladder. Ready-made glasses were then provided and 30 minutes to an hour later, their subjective wellbeing and work performance was remeasured. Twenty women entrepreneurs were interviewed to understand their lived experience with uncorrected presbyopia. RESULTS: Two-hundred-seventeen women entrepreneurs were included in the survey (mean age 51.6 years, SD 8.64). Women entrepreneurs had a mean subjective wellbeing score of 3.32 (SD 1.10) pre-correction and 5.99 (SD 1.13) post-correction (p < .001), and a mean self-rated current work performance score of 4.62 (SD 1.36) before correction and 5.47 (SD 1.35) post-correction (p < .001). One-hundred-and-ninety (87.6%) and 121 women entrepreneurs (55.8%) rated their current subjective wellbeing and work performance scores < 5, respectively. Around 1/4 of women entrepreneurs reported having severe difficulties with near tasks. CONCLUSION: Poor vision at a close distance caused by uncorrected functional presbyopia negatively affected economic, physical and psychosocial aspects of women entrepreneurs' lives. Subjective wellbeing and self-reported work productivity scores improved significantly shortly after presbyopia was corrected. More research with longer follow-up is needed to understand the full benefits of correcting presbyopia.

Refractive error, eye care needs and attitude towards spectacle wearing among older Zanzibari craftswomen and implications for developing women-targeted services: a cross-sectional study.

BACKGROUND: Aged Zanzibari women are in a disadvantaged position, having high demand for near-vision spectacles. Currently, there is no information on the eye health status of craftswomen, which makes planning a women-targeted project to deliver eye health services to older craftswomen in Zanzibar difficult. We assessed the prevalence of vision impairment, refractive error, presbyopia, effective spectacle coverage (distance and near) and attitude towards spectacle wearing among older Zanzibari craftswomen. METHODS AND ANALYSIS: This was a cross-sectional study. Unaided and presenting distance and near vision of craftswomen 35 years and older were assessed at the women's co-operatives. We determined the number of those with distance vision poorer than 6/12 and their causes (distance-vision impairment), the number of those with near vision poorer than N8 at 40 cm (presbyopia) and the number of those whose distance and/or near-vision needs were met adequately with their habitual spectacles (effective distance and near spectacle coverages). A piloted and validated questionnaire (15 statements) was used to determine their attitude towards spectacle wearing. RESULTS: In all, 263 craftswomen participated in the survey (mean age 52.1 years±9.4 years). The prevalence of distance vision impairment among the craftswomen was 29.7% (95% CI 24.2% to 35.6%), the primary cause being uncorrected refractive error (n=51, 65.4%), and none were corrected. The prevalence of presbyopia was 86.6% (95% CI 81.5% to 90.7%, n=231) and the effective near spectacle coverage was 0.99%. The craftswomen showed a positive attitude towards spectacle wearing (strongly agree or agree) based on 12 out of 15 statements. CONCLUSION: The high burden of vision impairment, uncorrected distance refractive error and presbyopia, and a positive attitude towards spectacle wearing among older craftswomen in Zanzibar indicated the need for women-targeted eye health programmes in low-resource settings.

How does a pair of near-vision spectacle correction empower older Zanzibari craftswomen?: A qualitative study on perception.

BACKGROUND: Studies have shown that correcting presbyopia among women could increase short-term income and quality of life. However, it is unclear whether these short-term outcomes translate to long-term empowerment. This is partly due to women's empowerment being under-studied in the eye health field. Hence, we attempted to understand Zanzibari craftswomen's perception of how near-vision spectacle correction could empower them. METHODS: Semi-structured interviews were conducted with 24 craftswomen with presbyopia (7 to 21 April 2022), identified from Zanzibari cooperatives using quota and heterogeneity sampling. We included a sample of tailors, beaders/weavers, and potters who were 40 years and older. Directed content analysis was performed on interview transcripts. RESULTS: Two themes and seven sub-themes emerged from the data. Craftswomen perceived that at the personal level, near-vision spectacle correction could improve their economic empowerment (better income and savings and buying things for themselves), psychological empowerment (more self-confidence and decision-making), political empowerment (taking up leadership roles), and educational empowerment (acquiring new skills). At a relational level, they perceived that near-vision spectacle correction could bring about economic empowerment (ability to buy things for the family), social empowerment (ability to participate in social activities), and educational empowerment (ability to educate other women). CONCLUSION: Older craftswomen perceived that correcting near vision could empower them at personal and relational levels that encompass economic, psychological, social, political and educational empowerment. The findings laid the foundation for future research into eye health and women's empowerment.

Does an integrated school eye health delivery model perform better than a vertical model in a real-world setting? A non-randomised interventional comparative implementation study in Zanzibar.

BACKGROUND: Few studies on school eye health programmes have shown they were cost-effective. We compared the performance (Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM)) between an integrated model (IM) and a vertical model (VM) of school eye health delivery in Zanzibar. METHODS: The set of RE-AIM performance indicators of the IM (n=9) and VM (n=10) cohorts was compared. The VM implemented only the eye health interventions, while the IM had the eye health interventions conducted within the school feeding programme. Semistructured interviews were conducted with 36 stakeholders to understand the challenges and outcomes experienced when implementing both models. RESULTS: The IM achieved higher screening coverage, voluntary follow-up rate, screening validity and spectacle compliance than VM. This was due to effective coordination between implementers, motivated teachers to prevent vision problems and related negative impacts in children, and activities implemented timeously post-training. Both models recorded low wearing compliance. All schools in the IM cohort completed screening activities, but two schools in the VM cohort did not. Both models ceased activities after the funding stopped. Local stakeholders emphasised that evidence from this study can be used to advocate for more resources for children's eye health. CONCLUSIONS: The IM cohort achieved better reach, effectiveness, adoption rate and implementation performance than the VM cohort. The poor maintenance performance indicators in both arms postfunding call for improvement to the implementation strategy to ensure the sustainability of school eye health. In the optics of scaling up, an integrated approach is recommended.

Is an integrated model of school eye health delivery more cost-effective than a vertical model? An implementation research in Zanzibar.

OBJECTIVE: To review and compare the cost-effectiveness of the integrated model (IM) and vertical model (VM) of school eye health programme in Zanzibar. METHODS AND ANALYSIS: This 6-month implementation research was conducted in four districts in Zanzibar. Nine and ten schools were recruited into the IM and VM, respectively. In the VM, teachers conducted eye health screening and education only while these eye health components were added to the existing school feeding programme (IM). The number of children aged 6-13 years old screened and identified was collected monthly. A review of project account records was conducted with 19 key informants. The actual costs were calculated for each cost categories, and costs per child screened and cost per child identified were compared between the two models. RESULTS: Screening coverage was 96% and 90% in the IM and VM with 297 children (69.5%) from the IM and 130 children (30.5%) from VM failed eye health screening. The 6-month eye health screening cost for VM and IM was US$6 728 and US$7 355. The cost per child screened for IM and VM was US$1.23 and US$1.31, and the cost per child identified was US$24.76 and US$51.75, respectively. CONCLUSION: Both models achieved high coverage of eye health screening with the IM being a more cost-effective school eye health delivery screening compared with VM with great opportunities for cost savings.

Prevalence of refractive error, presbyopia and spectacle coverage in Kahama District, Tanzania: a rapid assessment of refractive error.

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 district of Tanzania. METHODS: A cross-sectional community-based survey was conducted using 54 randomly selected clusters. Respondents 15 years and older were interviewed and underwent standardised clinical eye examinations. Uncorrected refractive error (URE) was defined as presenting vision worse than 6/12 that could be corrected to better than 6/12 using a pinhole. Spectacle coverage was defined as the proportion of need that was met (those that improved from unaided vision with their own spectacle correction). RESULTS: A total of 3,230 subjects (99.75 per cent of 3,240 eligible) participated in the study with 57.2 per cent males and the median age of participants was 35 years (inter-quartile range, 24 to 49). The prevalence of visual impairment was 10.4 per cent (95% CI 9.4 to 11.4) and was lower in those who had completed their primary school education (odds ratio (OR) 0.54, 95% CI: 0.40 to 0.72) and highest in subjects 40 years and older (OR 3.17, 95% CI: 2.14 to 4.70) and farmers (OR 8.57 95% CI: 2.27 to 32.43). Refractive error prevalence was 7.5 per cent (95% CI: 6.65 to 8.54) and this was highest in participants over 40 years (OR 1.60, 95% CI: 1.14 to 2.25) and in students (OR 3.64, 95% CI: 1.35 to 9.86). Prevalence of presbyopia was 46.5 per cent (773/1,663, 95% CI: 44.34 to 48.75). Spectacle coverage for refractive error and presbyopia was 1.69% (95% CI: 0 to 3.29) and 0.42% (95% CI: 0 to 1.26), respectively. CONCLUSION: Uncorrected refractive error is a public health challenge in the Kahama district and sustainable service delivery and health promotion efforts are needed.
