When intraocular pressure cannot be controlled with medications or laser alone minimally invasive glaucoma surgery (MIGS) may be recommended. In mild to moderate cases MIGS can reduce or eliminate the need to continue using glaucoma medications in the majority of patients. In more advanced cases MIGS may be needed in conjunction to the glaucoma medications.

iStent is a microscopic stent that is implanted at the time of cataract surgery into the drain of the eye to create a permanent tunnel for fluid outflow. It helps decrease intraocular pressure and treat vision loss related to glaucoma. Because the iStent is extremely small and implanted inside the eye patients are not able to see or feel it.

The Kahook Dual blade is designed to carefully excise a strip of the drain of the eye (trabecular meshwork). It helps decrease intraocular pressure and treat vision loss related to glaucoma. Goniotomy can be performed at the time of cataract surgery or as a stand alone procedure.

Endocyclophotocoagulation (ECP) is a laser procedure performed at the time of cataract surgery to reduce the amount of fluid formation in the eye. It helps decrease intraocular pressure and treat vision loss related to glaucoma. The laser is painless and very effective.

Canaloplasty utilizes a microcatheter or tube placed in the Canal of Schlemm (the natural site of drainage for healthy eyes) to enlarge the drainage canal, relieving pressure inside the eye. Studies have been published demonstrating long-term efficacy and safety.

Examples of canaloplasty devices include ABiC and Omni.
