5. Study Description
Brief Summary
The purpose of this study is to compare the safety and effectiveness of trabeculectomy with ologen (OculusGen) Biodegradable Collagen Matrix Implant and trabeculectomy without antifibrotic agents.
Detailed Description
Study Objective: To determine the safety and effectiveness of the ologen (OculusGen) Biodegradable Collagen Matrix Implant in filtration surgery. The primary endpoint is to prove the effectiveness via the reduction of IOP, and the secondary endpoint is to prove the safety via the incidence of complications and adverse events.
Study Design: The study is designed as an open-label, randomized, parallel, comparative study. Patients who meet the inclusion/exclusion criteria and sign informed consent will be included. After enrollment, patients will be randomized into two groups: trabeculectomy with OculusGen implant or trabeculectomy without antifibrotics.
Follow-Up: There will be 7 post-operative and follow-up visits within 6 months of surgery: postoperative days 1, 7, 14, 30, 60, 90 and 180. A window of ± 7 days is allowed for the 30, 60, 90 day visits and ± 14 days for the 180 day visits. Further follow-up of subjects after the trial will be the responsibility of the investigator.
