Brief Summary

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

1. Study objective: To assess the efficacy and safety of collagen matrix implant (Ologen®; OLO) in phacotrabeculectomy and to compare with mitomycin C (MMC) augmented phacotrabeculectomy.
2. Study Design: The study is designed as a prospective randomized trial. Patient who meet the inclusion/exclusion criteria and sign the informed consent form will be included for this study.
3. Follow-Up: This investigation is including 7 post-operative visits and follow-up within 12 months from the date of surgery. Patients should be seen at postoperative days 1, 7, 30, 90, 180, 270 and 360.
