Detailed Description
The COMPASS Trial (TMI-09-01/NCT01085357) 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 COMPASS Trial, 374 subjects undergoing cataract surgery were randomized to the CyPass group and received the CyPass Micro-Stent, whereas 131 subjects underwent cataract surgery alone. All subjects were to be followed for 2 years postoperatively. Four hundred eighty (480) subjects completed this study.
The COMPASS XT Trial (TMI-09-01E/GLD122b-C001/NCT02700984) was designed to collect safety data beyond 24 months postoperatively for subjects who completed the COMPASS Trial. In COMPASS-XT, clinical data was collected at 36 months, 48 months, and 60 months postoperatively for a total of 5-year follow-up across the 2 studies.
In this trial, COMPASS XXT, clinical data will be collected annually for the subjects who were implanted with the CyPass Micro-Stent in the COMPASS TRIAL until the subject reaches 10 years post-CyPass implantation. For some subjects, the first visit will be at or after 10 years post-CyPass implantation, and therefore the first visit may coincide with the Exit visit.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: CyPass Micro-Stent CyPass Micro-Stent placed in the angle of the eye at the conclusion of cataract surgery (COMPASS trial) |
Device: CyPass Micro-Stent
The CyPass Micro-Stent is a small tube with a through-lumen designed to redirect aqueous fluid from the front into the back of the eye. The device is implanted after completion of cataract surgery.
