Micro-Invasive Glaucoma Surgery


Micro-invasive glaucoma surgery (MIGS) is the latest advance in surgical treatment for glaucoma, which aims to help reduce pressure inside the eye to prevent or reduce damage to the optic nerve. MIGS typically require shorter operation time and allow for more rapid recovery. MIGS procedures work by using microscopic-sized equipment and tiny incisions.

Since MIGS procedures have a low risk of complications and provide long-term treatment benefits, they have been touted overall as safer than traditional trabeculectomy or tube shunt surgeries. This is because they do not have some of the associated complications from trabeculectomy and tube shunt procedures, such as too low eye pressure (hypotony) and bleb infection.

What is the OMNI Glaucoma Treatment System?

The OMNI Glaucoma Treatment System is the only device that combines two well-established micro-invasive glaucoma surgery (MIGS) procedures into one using a single device and single clear corneal incision. One device. One incision.

It is a tool, not a treatment. With dual mechanisms of action targeting the trabecular meshwork and collector channels, OMNI is designed to address the entire natural trabeculocanalicular outflow pathways to reduce intraocular pressure in adult patients with open-angle glaucoma.

What causes glaucoma?

A healthy eye drains continuously and without obstruction. When blockages in the natural drainage system develop, increasing intraocular pressure (IOP), a life-long disease called glaucoma develops. If the high eye pressure is left untreated, it may result in irreversible optic nerve damage that can ultimately lead to blindness.

How does FSN Eye Center use the OMNI Glaucoma Treatment System?

At FSN Eye Center, our eye doctors use the OMNI device to perform canaloplasty and goniotomy as a MIGS procedure for their glaucoma patients.

What is a canaloplasty?

Canaloplasty is an open-angle glaucoma surgery–one of the several newer surgical alternatives to lower pressure for patients with glaucoma. 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.

What is goniotomy?

Goniotomy is a surgical procedure for congenital glaucoma. The eye doctor uses a lens called a goniolens to see the structure of the front part of the eye (anterior chamber). An opening is made in the trabecular meshwork, the group of tiny canals located in the drainage angle, where the fluid leaves the eye. The new opening provides a way for fluid to flow out of the eye.

Who is a candidate for the OMNI Glaucoma Treatment System?

The OMNI Glaucoma Treatment System is usually reserved for patients with stable, mild-to-moderate open-angle glaucoma or congenital glaucoma and who do not require complex surgery.

Who is not a candidate for the OMNI Glaucoma Treatment System?

You would not be a candidate for surgery using this system if you have an eye condition (e.g., corneal edema, corneal haze, or corneal opacity) that prohibits sufficient visualization required for safe and successful cannula and microcatheter placement
