A removable polyamide suture was placed into the lumen of the MicroShunt during implantation to prevent early postoperative hypotony.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Thirty-one patients undergoing stand-alone glaucoma surgery with implantation of a PreserFlo MicroShunt and an intraluminal occlusion were retrospectively reviewed and compared to a control group without occlusion. Inclusion criteria were diagnosis of primary open-angle glaucoma or secondary open-angle glaucoma due to pseudoexfoliation or pigment dispersion.

Postoperative removal of the occluding suture resulted in a mean IOP reduction in 11.1\u2009\u00b1\u20097.6\u00a0mmHg. Mean visual acuity was 0.43\u2009\u00b1\u20090.24 logMAR during the first postoperative examination. The interval with the occluding intraluminal suture in place varied from days to 2\u20133\u00a0weeks.
