A Modern Approach To Glaucoma Management

Minimally invasive glaucoma surgeries (MIGS) represent a modern approach to managing intraocular pressure (IOP) in patients with mild to moderate glaucoma. These procedures are designed to reduce eye pressure by improving the eye’s natural fluid drainage, using techniques that involve smaller incisions, less tissue disruption, and generally shorter recovery times than traditional glaucoma surgeries.

When medications aren’t enough

MIGS procedures are often considered when medications alone are not achieving adequate pressure control, or when a patient is looking for an alternative to long-term use of eye drops. They can also be a good option when combined with other procedures, such as cataract surgery.

Spotlight on iStent

The iStent is a very small implant, made of surgical-grade titanium, that is inserted into the eye’s drainage system through a tiny incision. Its purpose is to help fluid flow more freely out of the eye, which helps lower intraocular pressure. Because of its size and placement, the stent is not visible or felt by the patient once in place.

This procedure is often performed at the same time as cataract surgery, offering the benefit of addressing both conditions in a single surgical event. It is typically recommended for patients with early to moderate open-angle glaucoma who are seeking improved pressure control with the potential to reduce or eliminate the need for glaucoma medications.

Trabectome: Clearing the pathway for fluid flow

Trabectome surgery is another minimally invasive procedure used to treat open-angle glaucoma. During this surgery, a small device is inserted into the eye to remove a portion of the trabecular meshwork—an area of tissue responsible for draining fluid from the eye. By clearing this pathway, fluid is able to exit the eye more efficiently, resulting in lower eye pressure.

The procedure uses a combination of gentle electrical energy and irrigation to precisely remove the tissue without damaging surrounding structures. Like the iStent, trabectome surgery is generally well tolerated and may be combined with cataract surgery if needed.

Evaluating the benefits of MIGS

Minimally invasive glaucoma procedures are not suitable for every type or stage of glaucoma, but they offer an appealing option for many patients due to their safety profile, faster recovery, and reduced reliance on daily medications. These procedures are typically performed on an outpatient basis, and most patients resume normal activities shortly after surgery.

Partnering with your ophthalmologist

Your ophthalmologist will assess several factors—including the type and severity of your glaucoma, your current eye pressure, and how your eyes have responded to other treatments—before recommending a MIGS procedure. In many cases, these techniques are part of a long-term glaucoma management plan that balances effectiveness with quality of life.

If you are interested in learning more about MIGS and whether it may be appropriate for you, speak with your eye care provider. Early and effective management of glaucoma is key to preserving your vision and maintaining eye health over time.
