Introduction: To evaluate the efficacy and safety of PreserFlo MicroShunt in primary open angle glaucoma (POAG) eyes after a single failed trabeculectomy.
Methods: Retrospective review of POAG eyes with a failed trabeculectomy that underwent PreserFlo MicroShunt implantation from March 2019 to November 2019, in two Italian glaucoma centers. Pre- and postoperative data were collected and compared.
Results: A total of 31 surgeries in 31 patients were reviewed. Mean preoperative IOP and mean preoperative number of medications were 24.12 ± 3.14 mmHg and 3.29 ± 0.64, respectively, and decreased to 12.56 ± 2.64 mmHg and 0.46 ± 0.77 at the 12-month postoperative follow-up visit (p < 0.01). The most frequent adverse events were transient hypotony (6 eyes, 19.3%) and choroidal effusion (3 eyes, 9.6%). In all cases spontaneous resolution was observed, with no intervention.
Conclusion: In POAG eyes with a single failed trabeculectomy, the PreserFlo MicroShunt was safe and effective in reducing the IOP after a 12-month follow-up. The PreserFlo MicroShunt may represent a viable choice as a second surgery.

: The PreserFlo™ MicroShunt (PFMS) is a bleb-forming device considered to be less invasive than traditional glaucoma surgery such as trabeculectomy. This study evaluates the 1-year success rates as well as safety profile of PFMS in patients having high intraocular pressure (IOP) and/or glaucoma refractory to drop therapy with a history of prior intravitreal dexamethasone therapy. : A total of 16 eyes after PFMS implantation due to elevated IOP after intravitreal dexamethasone implant (DEX-I) administration were included in this retrospective cohort study.

To assess the efficacy of using a nylon suture as a stent in the PreserFlo MicroShunt (PMS) lumen to prevent postoperative hypotony, 59 eyes that underwent PMS implantation with follow-up for > 6 months were analyzed. Patients were divided into no intrastenting (NST) and intrastenting (ST) groups, with the ST group subdivided into 9 - 0 nylon suture fully placed (9 F), 9 - 0 nylon suture placement in only half of the lumen (9 H), 10 - 0 nylon suture fully placed (10 F), and 10 - 0 nylon suture placement in only half of the lumen (10 H). The distribution was as follows: 23 eyes in the NST group, 10 in the 9 F group, 9 in the 9 H group, 11 in the 10 F group, and 6 in the 10 H group.

Purpose: To assess the efficacy and safety of PreserFlo MicroShunt (PMS) combined with mitomycin C in patients with medically treated primary open-angle glaucoma (POAG).
Study Design: A retrospective observational study.
Methods: The study examined 83 eyes from 83 patients with medically treated glaucoma surgery naive POAG.

Background/ Aims: To analyze the longitudinal change in Bruch's membrane opening minimal rim width (BMO-MRW) and peripapillary retinal nerve fiber layer (pRNFL) thickness using optical coherence tomography (OCT) after implantation of a PRESERFLO® microshunt for surgical glaucoma management in adult glaucoma patients.
Methods: Retrospective data analysis of 59 eyes of 59 participants undergoing implantation of a PRESERFLO microshunt between 2019 and 2022 at a tertiary center for glaucoma management. Surgical management included primary temporary occlusion of the glaucoma shunt to prevent early hypotony.
