The iStent® Trabecular Micro-Bypass Stent is indicated for use in conjunction with cataract surgery for the reduction of intraocular pressure in adult patients with mild to moderate open-angle glaucoma currently treated with ocular hypotensive medication.
It is contraindicated in eyes with primary or secondary angle closure glaucoma, including neovascular glaucoma, as well as in patients with retrobulbar tumor, thyroid eye disease, Sturge-Weber Syndrome or any other type of condition that may cause elevated episcleral venous pressure.
The most common post-operative adverse events reported include early post-operative corneal edema, best visual acuity loss, posterior capsular opacification, stent obstruction, early post-operative anterior chamber cells, and early post-operative corneal abrasion.
