Table 3 Adjusted mean intraocular pressure (IOP) difference from preoperative values in XEN63-standalone and XEN63 + Phacoemulsification groups. The model included "Surgery" (XEN63-standalone versus XEN63 + Phaco) as a factor and age, preoperative IOP, preoperative number of ocular hypotensive drugs, pachymetry, and dose of mitomycin-C as covariates.
