Canaloplasty is a relatively new surgical option in the treatment of open-angle glaucoma. This non-perforating technique uses a microcatheter connected to a flickering red light laser source, which is inserted within Schlemm’s canal. A 10-0 prolene suture is tied to the distal tip of the microcatheter, which is gently guided out of the canal in the opposite direction and then left tensioned while a small amount of viscoelastic agent is injected in Schlemm’s canal. The aim of this surgery is to facilitate aqueous outflow through natural pathways, with less risks of post-operative complications.
