The iStent infinite effectively lowers intraocular pressure (IOP) and reduces the need for topical medications in patients with open-angle glaucoma, according to a poster presented at AGS 2025.
The multicenter, retrospective study included 64 eyes treated by 7 surgeons, with implantation performed either as a standalone procedure or alongside cataract surgery.
At 12-month follow-up, mean IOP had decreased from 18.1 mmHg to 13.8 mmHg, a 23% reduction (P = 0.001). The average number of IOP-lowering medications dropped by 51%, with 61% of eyes no longer requiring topical treatment compared to just 8% before implantation. Two-thirds of eyes achieved an IOP below 14 mmHg, and over a third reached levels below 12 mmHg.
The procedure was well tolerated, with no intraoperative complications. Reported adverse events were mild and resolved without lasting effects.
