Influence of Cataract Awareness on Eye-Care Service Utilization among Older Adults in Nigeria

Abstract

Cataract is a major cause of avoidable visual impairment and blindness among older adults and represents an important public health and eye-health concern in Nigeria. Although cataract can often be effectively managed through appropriate eye-care services and surgical treatment, delayed presentation and limited utilization of eye-care services may contribute to unnecessary vision loss and reduced quality of life. Cataract awareness provides older adults with information about the nature of cataract, common symptoms, risk factors, progression of visual impairment, available treatment options, the importance of early eye assessment, and appropriate sources of eye-care services. Eye-care service utilization refers to the use of appropriate eye-health services by individuals, including routine eye examinations, visual assessment, consultation with eye-care professionals, cataract diagnosis, referral, treatment, and follow-up care. In Nigeria, inadequate utilization of eye-care services among older adults may be associated with limited awareness of cataract, misconceptions about its causes and treatment, financial constraints, geographical barriers, fear of surgery, reliance on traditional remedies, transportation difficulties, and limited availability of accessible eye-care services. Effective cataract awareness may improve older adults' understanding of cataract and encourage timely utilization of appropriate eye-care services. Against this background, this study investigates the influence of cataract awareness on eye-care service utilization among older adults in Nigeria. The study is anchored on the Health Belief Model, Social Cognitive Theory, and the Knowledge-Attitude-Practice framework. The Health Belief Model provides a framework for understanding older adults' decisions to utilize eye-care services through perceived susceptibility to cataract-related visual impairment, perceived severity of vision loss, perceived benefits of early eye-care utilization, perceived barriers, and cues to action. Social Cognitive Theory emphasizes the interaction between knowledge, self-efficacy, social influences, environmental conditions, and health-seeking behaviour in shaping eye-care utilization. The Knowledge-Attitude-Practice framework provides a basis for examining how cataract awareness may improve knowledge and attitudes and influence eye-care service utilization. Collectively, these theoretical perspectives provide a suitable framework for explaining how cataract awareness may influence eye-care service utilization among older adults in Nigeria. The study will adopt a quantitative quasi-experimental research design. Primary data will be collected from older adults in selected communities, primary healthcare centres, hospitals, eye-care facilities, and other appropriate settings in Nigeria using a structured interviewer-administered questionnaire, cataract awareness assessment, and eye-care service utilization assessment tool. A multistage sampling technique will be employed to select states, local government areas, communities, households, healthcare facilities, and eligible older adults. Where feasible, selected communities or participant groups will be assigned to intervention and comparison groups. Older adults in the intervention group will receive structured cataract-awareness education covering the meaning and symptoms of cataract, risk factors, progression of visual impairment, common misconceptions, available treatment options, benefits of early assessment and treatment, importance of routine eye examinations, available eye-care services, and appropriate referral pathways. Eye-care service utilization will be assessed using indicators such as attendance for eye examinations, consultation with eye-care professionals, visual assessment, cataract diagnosis, referral attendance, treatment utilization, cataract surgery uptake where indicated, and follow-up attendance. Where feasible, self-reported utilization will be verified using healthcare records or referral documentation. Descriptive statistics will be used to summarize participants' sociodemographic characteristics, previous exposure to eye-health education, cataract awareness levels, history of eye-care utilization, and patterns of service utilization. Inferential statistical techniques, including chi-square tests, paired-sample tests, independent-sample tests, and logistic or multiple regression analysis, will be used to determine the influence of cataract awareness on eye-care service utilization. Where appropriate, utilization before and after the intervention will be compared. Diagnostic tests will also be conducted to assess the reliability of the research instruments, model assumptions, goodness of fit, and robustness of the findings. The study is expected to find that cataract awareness has a significant positive influence on eye-care service utilization among older adults in Nigeria. Older adults exposed to structured cataract-awareness education are expected to demonstrate improved knowledge of cataract symptoms, risk factors, progression, treatment options, and the importance of timely eye-care utilization. Increased awareness is expected to encourage individuals experiencing visual difficulties to seek professional eye assessment rather than delaying care or relying exclusively on unverified traditional remedies. Education may also improve understanding of cataract treatment and reduce misconceptions and fear associated with cataract surgery and other eye-care procedures. However, awareness alone may not guarantee utilization because older adults may continue to experience barriers such as treatment costs, limited availability of eye-care professionals, geographical distance, transportation difficulties, dependence on caregivers, fear of surgery, and inadequate access to specialized eye-care services. Consequently, cataract awareness may be most effective when supported by affordable and accessible eye-care services, community-based eye-health programmes, effective referral systems, transportation support, and sustained public education. The study is expected to contribute to the literature on cataract awareness, eye-care service utilization, geriatric eye health, health education, health-seeking behaviour, avoidable blindness prevention, health promotion, and public health in Nigeria by providing empirical evidence on the influence of cataract awareness on eye-care service utilization among older adults. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, state ministries of health, ophthalmology and optometry services, hospitals, primary healthcare centres, eye-care organizations, community health workers, public health practitioners, health educators, development partners, and policymakers regarding strategies for improving early detection and treatment of cataract. The study will also provide evidence-based recommendations for integrating cataract awareness into primary healthcare and community health programmes, expanding community-based eye screening, strengthening referral systems, improving access to affordable cataract treatment, addressing misconceptions about cataract surgery, and promoting timely utilization of eye-care services among older adults in Nigeria.
