Unmet need for presbyopia correction and its associated factors among school teachers in Hawassa city, South Ethiopia

Abstract

Abstract Background Presbyopia is a decline in the amplitude of accommodation with the onset in the age range 40–45 years affecting near visual task performance. As the age of presbyopia onset coincides with productive age, it results in great productivity loss especially in those with high near visual demand like teachers. A maximum near vision potential is essential for teachers in ensuring the quality of education, as most of the students’ evaluations and scripts are assessed manually in Ethiopia. The prevalence of unmet need for presbyopia correction among school teachers ranges from 38.5–70.4% worldwide. Though presbyopia is a common ocular condition, there is limited evidence regarding the unmet need for presbyopia correction in Ethiopia as well as in Hawassa city. Therefore, this study aimed to determine the magnitude of unmet need for presbyopia correction and its associated factors among school teachers in Hawassa city, South Ethiopia. Methods A school-based cross-sectional study was conducted among teachers older than 35 years. A simple random sampling technique was used to select participants using name lists as a sampling frame from 69 schools. The participants selected underwent for distance and near visual acuity test. Those with distance visual acuity of 6/12 or worse were refracted before near visual acuity test. Information on the spectacle use and associated factors was obtained using the interviewer-administered questionnaire. Data analysis was done using Statistical Package for Social Sciences software version 20. Binary logistic regression analysis was performed to assess association between independent variables and the unmet need for presbyopia correction. Results A total of 459 study participants were included in the study with a response rate of 95.21%.The unmet need for presbyopia correction was 51.26% (95%CI: 46.7–55.6%). Female gender (AOR = 2.50; 95%CI: 1.51–4.15), age 36–45 (AOR = 4.12; 95%CI: 1.46–11.76), unaware of presbyopia (AOR = 2.36; 95%CI: 1.2–4.66) and self-rating of current vision as good (AOR = 3.5; 95%CI: 1.61–7.6) were factors significantly associated with the unmet need for presbyopia. Conclusions The burden of unmet need for presbyopia correction is a moderate priority according to the World Health Organization for presbyopia correction services criteria. A school-based presbyopia awareness creation program is important to reduce this huge burden.
