InnFocus MicroShunt Versus Trabeculectomy Study

Not Applicable
Completed
Conditions
Primary Open Angle Glaucoma
Interventions
Device: InnFocus MicroShunt
Procedure: Glaucoma Surgery
Registration Number
NCT01881425
Lead Sponsor
InnFocus Inc.
Brief Summary

Assess the safety and effectiveness of the InnFocus MicroShunt when used to lower intraocular pressure (IOP) in subjects with primary open angle glaucoma where the IOP is not controlled when using maximum tolerated glaucoma medications.

Detailed Description

This clinical trial is a prospective, randomized, controlled, multicenter, study. After informed consent is obtained, patients will be evaluated for eligibility based on glaucoma severity, eye health, and visual acuity.

Clinical follow up will be scheduled over the course of the 24 month study, and examinations will be repeated to monitor eye health. At the 1 and 2 year follow up, diurnal (IOP taken in the morning, mid-day, and afternoon in the same day) IOP evaluation will be done. Annual follow up will occur up to 2 years. The primary effectiveness endpoint is 20% or greater reduction in IOP from pre-op medicated IOP at 12 months.
