Stand-alone iStent infinite trabecular micro-bypass substantially reduced mean diurnal intraocular pressure (IOP) in patients with advanced to refractory open-angle glaucoma (OAG) who had failed prior medical or surgical treatment, according to a study presented at AAO 2021.
In this prospective multicenter investigational device exemption trial, 72 patients with OAG uncontrolled by prior surgical and/or medical therapy, were enrolled. At baseline, mean IOP was 23.4 mmHg; mean medication taken was 3.1; and patients had a mean of 2 prior surgeries.
All patients underwent a 3-stent, standalone trabecular bypass (The iStent infinite; Glaukos) procedure.
At 12 months, there was a meaningful reduction in IOP from baseline, with 76% of patients achieving ≥20% reduction in mean diurnal IOP on the same or fewer medications and ≥50% of patients achieving IOP reduction ≥30% in mean diurnal IOP from baseline.
Participants had a 13% reduction in medication burden at 12 months, from 3.1 medications at baseline to 2.7 at 12 months after surgery.
