PURPOSE: To compare the efficacy and safety of the XEN45 implant with that of trabeculectomy (TRAB), either alone or in combination with phacoemulsification (PHACO), in patients with open-angle glaucoma (OAG). METHODS: Retrospective, single-center and comparative study conducted on OAG patients. Patients were divided into four groups: group 1 (XEN alone); group 2 (XEN+PHACO); group 3 (TRAB alone); group 4 (TRAB+PHACO). For statistical purposes, groups 1 and 2 were combined (XEN implant), while groups 3 and 4 were also combined (TRAB surgery). The main outcome measure was intraocular pressure (IOP). RESULTS: Ninety-one patients (121 eyes; 65 XEN and 56 TRAB) were included. IOP reduction was - 6.7 (- 10.4 to - 3.0) mmHg, p = 0.0013; - 3.5 (- 5.0 to - 2.0) mmHg, p < 0.0001; - 8.1 (- 10.4 to - 5.9) mmHg, p < 0.0001l; and - 7.3 (- 9.3 to - 5.3) mmHg, p < 0.0001 in the XEN alone, XEN+PHACO, TRAB alone, and TRAB+PHACO, respectively. At month 12, an IOP ≥ 6 and ≤ 16 mm without treatment was achieved by 44 (67.7%) and 43 (76.8%), p = 0.2687 in the XEN implant and the TRAB surgery groups, respectively. The mean number of antiglaucoma medications was significantly reduced in all the study groups (p < 0.0001 each). Needling occurred in 20.0% (13/65) of eyes in the XEN implant group, while hyphema occurred in 30.4% (17/56) of eyes in the TRAB group. CONCLUSIONS: XEN implant, either alone or in combination with phacoemulsification, significantly reduces both IOP and the number of antiglaucoma medications to a similar rate than trabeculectomy, but with a better safety profile.
