Mean number of ocular hypotensive medications in the Xen 63 and MicroShunt groups throughout study follow-up. As compared to preoperative values, the mean number of ocular hypotensive drugs was significantly reduced in both groups, at every time point measured, p < 0.0001. No significant differences were observed between both groups throughout the study follow-up.
