Summary

This study compares two small drainage devices (XEN-63 and PRESERFLO) placed during a single surgery to lower eye pressure in adults with open-angle glaucoma. About 166 participants will be randomly assigned to one device and followed for two years. The goal is to see which works better at reducing pressure and preserving vision.
