“…Few studies report the cost-effectiveness of RE correction. It has been suggested that screening and spectacles provision are highly cost-effective for school children [37,38] and estimates in the adult Australian population over a five-year horizon were approximately US$ 45 per QALY gained [39]. …”

Objective: To estimate the cost-effectiveness of cataract surgery and refractive error/presbyopia correction in Zambia. Methods: Primary data on costs and health related quality of life were collected in a prospective cohort study of 170 cataract and 113 refractive error/presbyopia patients recruited from three health facilities. Six months later, follow-up data were available from 77 and 41 patients who had received cataract surgery and spectacles, respectively. Costs were determined from patient interviews and micro-costing at the three health facilities. Utility values were gathered by administering the EQ-5D quality of life instrument immediately before and six months after cataract surgery or acquiring spectacles. A probabilistic state-transition model was used to generate cost-effectiveness estimates with uncertainty ranges.Results: Utility values significantly improved across the patient sample after cataract surgery and acquiring spectacles. Incremental costs per Quality Adjusted Life Years gained were US$ 259 for cataract surgery and US$ 375 for refractive error correction. The probabilities of the incremental cost-effectiveness ratios being below the Zambian gross national income per capita were 95% for both cataract surgery and refractive error correction. Conclusion: In spite of proven cost-effectiveness, severe health system constraints are likely to hamper scaling up of the interventions.

Purpose of Review To evaluate the epidemiology of uncorrected refractive errors (URE) in adults both in the US and globally, health outcomes impacted by URE, common barriers to treatment, and propose potential interventions. Recent Findings URE is the main cause of visual impairment (VI) and the second leading cause of blindness globally. Rates of URE are rising, and cause disability that reduces productivity, economic earnings, and the quality of life of affected individuals. Economic barriers, health care access, and socio-cultural constraints are among the most fundamental barriers to correcting URE. However, innovative approaches are poised to lower rates of URE. Summary URE is a leading cause of preventable VI with serious health consequences. Numerous social and financial barriers are associated with the high prevalence of URE in low-income adults. Novel delivery programs for eyeglasses and programs to provide refractive surgery to correct refractive error could decrease rates of URE.
