Abstract Purpose:The aim in this study was to compare the cost-effectiveness of endoluminal lacrimal duct recanalization(ELDR) and endonasal dacryocystorhinostomy(DCR) in treating nasolacrimal duct obstruction based on clinical outcomes and medical reimbursement costs.

Subjects and methods:Sixty-nine cases of acquired nasolacrimal duct obstruction who underwent ELDR or DCR at our clinic in 2023 were retrospectively reviewed. Cases requiring treatment beyond those than nasolacrimal obstruction or postoperative complications were excluded. The costs were calculated at total medical reimbursement points during the observation period, and effectiveness was defined as surgical success(patent irrigation with symptom resolution). The cost-effectiveness ratio(CER) and incremental cost-effectiveness ratio(ICER) were calculated.

Results:The mean cost per eye was \91,900 and \401,910 for ELDR and DCR, respectively. The success rates were 78% and 95% for ELDR and DCR, respectively yielding an ICER of \1,821,353 per additional success. Similar trends were observed in bilateral cases, for which ELDR was more cost efficient. Sensitivity analysis indicated that the CER of DCR was higher than that of ELDR when the ELDR success rate dropped below approximately 20%.

Conclusion:ELDR is more cost-effective than DCR in the short term according to the analysis of medical reimbursement data and clinical outcomes. ELDR may serve as a useful and economically efficient alternative procedure to DCR for nasolacrimal duct obstruction above a certain level of surgical success.
