Clinical outcomes of the EyeWatch system: three-year results.

IOP & Medical Therapy

Summary

Most device adjustments occurred within the first postoperative year, after which IOP remained stable without further intervention.

Abstract

WHAT IS KNOWN

The EyeWatch™ System (EWS) is an adjustable glaucoma drainage device that allows non-invasive postoperative intraocular pressure (IOP) control. Early studies have shown promising short- and mid-term results with EWS in managing refractory glaucoma.

WHAT IS NEW

This study presents the first three-year clinical outcomes of EWS implantation, showing a sustained IOP reduction from a preoperative mean of 34.6 mmHg to 13.6 mmHg, with all patients achieving IOP levels below 21 mmHg and a significant decrease in medication burden. Most device adjustments occurred within the first postoperative year, after which IOP remained stable without further intervention. A transient IOP elevation following MRI underscores the importance of monitoring EWS patients in the context of magnetic exposure.
