A review of canaloplasty.

Canaloplasty is a method of lowering intraocular pressure (IOP) by which a flexible, beacon-tipped microcatheter equipped with an ophthalmic viscosurgical device (OVD) delivery system is used to catheterize and introduce a suture into Schlemm's canal. Ligation of this suture provides tension on the canal and facilitates aqueous outflow. Canaloplasty is designed to be a blebless procedure that requires no antifibrotic agents and has been shown to safely and effectively lower IOP in patients with open-angle glaucoma (OAG) with minimal complications. Most importantly, no bleb-related adverse events are associated with this procedure. When contemplating surgical management of OAG, canaloplasty may be considered.
