Objective To estimate resource use and the costs of eye injuries in 2011–2012 in the Helsinki University Eye Hospital (HUEH), which covers 1.6 million people in Southern Finland. Methods This population-based study consisted of all new patients (1,151) with eye injuries in one year. The data were from hospital records, internal HUEH accountancy, and prospectively from questionnaires. The costs of direct health care, transportation, and lost productivity were obtained and estimated for the follow-up period of three months. The estimated future costs were discussed. Results During the follow-up, the total cost was 2,899,000 Euros (EUR) (= EUR 1,870,300/one million population), including lost productivity (EUR 1,415,000), direct health care (EUR 1,244,000), and transportation (EUR 240,000). The resources used included 6,902 days of lost productivity, 2,436 admissions and transportations, 314 minor procedures, 313 inpatient days, 248 major surgeries, and 86 radiological images. One open globe injury was the costliest (EUR 13,420/patient), but contusions had the highest overall cost (EUR 1,019,500), due to their high occurrence and number of follow-ups. Conclusions Eye injuries cause a major burden through high costs of direct health care and lost productivity: the imminent costs were EUR 1,870,000/one million population, and the future costs were estimated to EUR 3,741,400/one million population. Prevention remains the main factor to consider for better cost-efficiency.
