AIM: To evaluate the safety and efficacy outcomes of PRESERFLO™ MicroShunt implantation in patients with primary open-angle glaucoma. MATERIAL AND METHODS: Retrospective data analysis of 19 eyes of 12 patients, comprising 5 females and 7 males. The patients underwent surgery between August 2020 and February 2022. The follow-up period was 24 months after surgery. During the follow-up period, intraocular pressure (IOP), the need to apply topical antiglaucoma medication and its spectrum, visual field status, optic nerve target findings and postoperative complications were recorded. The indication for PRESERFLO™ MicroShunt implantation was primary open angle glaucoma (POAG), poorly controlled with maximum tolerated medical therapy. RESULTS: Average IOP was reduced from 19.05 ±5.58 mmHg preoperatively to 11.47 ±2.48 mmHg at 3 months postoperatively, 12.26 ±2.48 mmHg at 6 months postoperatively, 14.0 ±2.43 mmHg at 12 months postoperatively, 11.78 ±2.37 mmHg at 18 months postoperatively, and 12.73 ±2.51 mmHg at 24 months postoperatively (p.

INTRODUCTION: This study was performed to compare the efficacy and safety of PreserFlo MicroShunt (PMS) implantation with mitomycin C (MMC) applied by sub-tenon injection versus conventional application by MMC-soaked sponges. METHODS: This retrospective, 1-year cohort study included 100 eyes of 100 patients with glaucoma who underwent PMS implantation with MMC (0.4 mg/ml) delivered either by sub-tenon injection (50 eyes) or via soaked sponges (50 eyes). The primary outcome measure at 1 year was intraocular pressure (IOP) reduction, with complete success defined as an IOP reduction of ≥ 20% and achieving a target IOP of ≤ 21 or 18 mmHg without the use of medication. Secondary outcomes, including corneal endothelial cell density (CECD) loss, the number of medications, and complications, were assessed and compared between the groups. RESULTS: Sustained reductions in mean IOP were observed in both groups over the 1-year follow-up, with no significant differences between the groups. The complete success rate, with a target IOP of ≤ 21 mmHg after 1 year, was 19.3% in the sponge group and 26.4% in the injection group. The qualified success rate was 59.0% and 87.4% in the sponge and injection groups, respectively. A longer survival rate was observed in the injection group than in the sponge group when IOP was below 21 mmHg. The mean CECD significantly decreased (P < 0.01) from baseline to each postoperative follow-up time point in both groups. At 1 year postoperatively, the percentage of total CECD loss was 8.1% in the sponge group and 8.0% in the injection group. However, no significant differences in mean CECD values, the number of medications, or adverse events were found between the groups. CONCLUSIONS: PMS implantation with sub-tenon injection of MMC was comparable in terms of efficacy and safety to traditional MMC delivery via soaked sponges. However, the injection group demonstrated a significantly higher success rate than the sponge group.
