Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospective, concurrent controlled, open-label, multicenter study is designed to collect additional safety data through 5 years of follow-up for subjects randomized to either the treatment arm (PRESERFLO® MicroShunt with MMC) or the control arm (Trabeculectomy with MMC) of the INN-005 clinical study.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The objective of this study is to evaluate the long-term safety of the PRESERFLO® MicroShunt in subjects with Primary Open-Angle Glaucoma who have completed their Month 24 Follow-Up Visit in the INN-005 clinical study, by collecting safety data through 5 years post-operative follow-up.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

MicroShunt treatment group

Subjects previously randomized to this arm in pivotal study conducted under IDE G130028 were implanted with the device

PRESERFLO® MicroShunt

Intervention Type DEVICE

Device surgically implanted

Trabeculectomy control arm

Subjects previously randomized to this arm in pivotal study conducted under IDE G130028 underwent trabeculectomy procedure

Trabeculectomy

Intervention Type PROCEDURE

The procedure involves removal of a small portion of the trabecular meshwork and adjacent scleral tissue. Aqueous humor then drains into the subconjunctival space, creating a bleb on the external part of the eye, where it diffuses away.
