Abstract

BACKGROUND AND OBJECTIVE: To evaluate the economic impact in Spain derived from the introduction of the XEN®63 implant as a surgical alternative in the management of primary open angle glaucoma (POAG) with or without cataract in refractory patients. MATERIALS AND METHODS: A budget impact analysis was designed to estimate the costs of surgical treatment of POAG from the perspective of the Spanish National Health System (NHS), over a time horizon of 1?year. The comparators considered (trabeculectomy, deep non-perforating sclerectomy, Ahmed valve, iStent® Inject, Preserflo® microshunt and XEN®45) correspond to those used in Spanish public clinical practice. For the calculation of the target population, market shares and resource use in terms of follow-up visits, additional procedures and post-surgery complications, data from the literature were used and validated with a panel of 4 experts. Unit costs (; 2021) were obtained from the ESALUD database. RESULTS: The inclusion of XEN®63 could generate savings of ;2,569,737 after one year since its introduction, derived from savings in the cost of the implant and procedure (-;423,120; -0.7%), follow-up visits (-;777,407; -4.5%), additional procedures (-1,048,145; -20.6%) and post-surgery complications (-;321,065; -14.2%). CONCLUSIONS: The incorporation of XEN63®in the surgical arsenal for the treatment of refractory POAG with and without cataracts could generate savings for the NHS.
