The iStent inject device is comprised of two biocompatible titanium stents preloaded on a single-use sterile injector. Each stent contains four lateral outlet lumens to facilitate multidirectional outflow. The stents are placed ab internally through the trabecular meshwork into Schlemm’s Canal at approximately 2–3 h apart, providing access to up to 6 h of aqueous outflow [5 (link), 6 (link)]. Implantation is completed either following phacoemulsification (in combined-cataract cases) or as a standalone procedure, as described in the respective prior publications [3 (link), 4 (link)]. Following implantation, stent position and patency are confirmed via gonioscopy, viscoelastic is removed, and surgical wound closure is ensured. Postoperatively, patients were prescribed 1 week of topical antibiotic ciprofloxacin (Floxal®, Bausch&Lomb, Berlin, Germany) and four weeks of topical anti-inflammatory medication (Dexamethasone; Bausch&Lomb).
