Abstract

Introduction: Cataracts represent a significant public health issue and are the most prevalent vision disorder following refractive errors. They can restrict the economic, social, and psychological activities of those affected, thereby diminishing their quality of life. This study was undertaken to examine the willingness to pay for cataract surgery and the factors influencing this decision in selected medical centers in Urmia. The two-stage Heckman model was utilized to aid decision-making in financing this service.

Methods: This research was a descriptive-analytical study evaluating the economic aspects of health interventions, conducted from the patient's perspective. In this cross-sectional study, a sample size of 217 patients with cataract issues was selected using Michel Carson's table. These patients were from Imam Khomeini Hospital and Aftab Urmia Surgery Center in 2023. Data was collected using a conditional valuation approach to determine the maximum amount patients were willing to pay, as gathered through a questionnaire. The factors influencing the willingness to pay for cataract surgery were estimated using the two-stage Heckman regression model. The final effect value of each variable was calculated using Stata version 14 software.

Results: In this study, 81.11% of participants (176 individuals) expressed a willingness to pay for cataract surgery, with the average amount they were willing to pay being $206.3. However, out of the 217 respondents, 41 rejected the proposed amounts and were not willing to pay anything. The results of the Hemken model indicated that the income of patients and the size of their households significantly influenced their willingness to pay for cataract surgery. However, other variables investigated did not have a significant impact.

Conclusion: The study results revealed a significant influence of both income and household size on the likelihood of willingness to pay, as well as the extent of willingness to pay for cataract surgery. Consequently, it is crucial to formulate policies and provisions that guarantee access to cataract services, particularly for individuals from large households with low income and high costs.

Keywords: Cataract surgery; Contingent valuation; Two-stage Hemken model; Willingness to pay.
