Abstract Purpose The aim of the underlying study was to present a new surgical method in PreserFlo MicroShunt surgery for glaucoma. A removable polyamide suture placed into lumen during implantation prevent early postoperative hypotony. Methods Thirty-one patients undergoing stand-alone glaucoma with and an intraluminal occlusion were retrospectively reviewed compared control group without occlusion. Inclusion criteria diagnosis primary open-angle or secondary due pseudoexfoliation pigment dispersion. Patients history filtrating excluded. Results IOP decreased from 26.9 ± 6.6 18.0 9.5 mmHg at first day after implantation. Postoperative removal occluding resulted mean reduction 11.1 7.6 mmHg. Mean visual acuity 0.43 0.24 logMAR examination. interval place varied days 2–3 weeks. followed up 1 year. Conclusion Implantation combined prevented hypotony all patients. pressure reduced despite place.
