The Cost and Economics of Endoscopic Cyclophotocoagulation in the United Kingdom: A Tertiary Center Experience.

Precis: As the only microinvasive glaucoma surgery (MIGS) with a reusable component, the cost per procedure of endoscopic cyclophotocoagulation (ECP) diminishes with each successive use. We present a cost comparison of ECP with other MIGS devices, based on our clinical practice.

Purpose: ECP delivers diode laser via a reusable probe to the ciliary processes under direct visualization. The aim of our study is to evaluate the direct cost of ECP based on a retrospective review of cases and compare the cost per procedure with other MIGS devices.

Methods: We conducted a retrospective review of ECP procedures performed at St Thomas' Hospital over 4.5 years. The cost of the ECP endoscope and diode laser consoles, reusable probes, and maintenance contracts were obtained from the hospital procurement log. The on-site Central Sterile Services Department was contacted for probe sterilization and repackaging costs. The cost per device for ECP and commonly performed MIGS procedures were obtained from the product specialists of each company.

Results: A total of 332 procedures were performed using 37 ECP probes during the study period. Each reusable ECP laser probe was found to give an average of 8.97 laser treatments. The cost per procedure decreased over the course of 4.5 years from £819.43 for the first 42 cases to £341.50 after 332 cases. Compared with other MIGS devices, the cost per procedure of ECP after 100 procedures is second lowest to the Kahook Dual Blade and reduces with each successive procedure performed.

Conclusion: The ability to reuse each ECP probe significantly lowers the cost per procedure compared with other MIGS devices in the United Kingdom. The cost per procedure continues to reduce with each successive procedure.
