A Study to Assess Long-Term Safety of the CyPass Micro-Stent in Patients Completing the COMPASS Trial

The COMPASS Trial (TMI-09-01) was a prospective, randomized, comparative multicenter study to assess the safety and effectiveness of the CyPass Micro-Stent in subjects with primary open angle glaucoma who were undergoing cataract surgery. In the study, 505 subjects were randomized to either the CyPass group, who underwent cataract surgery and received the CyPass Micro-Stent, or the Control group, who underwent cataract surgery alone. All subjects randomized were to be followed for 2 years postoperatively. Four hundred eighty (480) subjects completed this study. The COMPASS-XT (TMI-09-01-E) Trial is designed to collect safety data beyond 24 months postoperatively for subjects who completed the COMPASS Trial. In COMPASS-XT, clinical data will be collected at 36 months, 48 months, and 60 months postoperatively for a total of 5 year follow-up across the 2 studies.
