MIGS (Minimally Invasive Glaucoma Surgery) at Washington Eye Institute

At Washington Eye Institute, our comprehensive glaucoma team uses minimally invasive glaucoma surgery (MIGS) to lower intraocular pressure (IOP) with microscopic devices and tiny incisions. These micro-invasive glaucoma procedures reduce the tissue trauma and risk associated with traditional glaucoma surgery. With glaucoma affecting more than 4 million U.S. adults, MIGS gives many patients a safer option to help control IOP. MIGS can often be performed at the same time as cataract surgery and as part of a tailored treatment plan based on each patient's stage of disease.

What Is Minimally Invasive Glaucoma Surgery?

Glaucoma is a progressive optic neuropathy — a group of conditions that damage the optic nerve, often (but not always) associated with elevated intraocular pressure (IOP). Because glaucoma can occur even with normal eye pressure, comprehensive evaluation beyond pressure checks alone is essential. Minimally invasive glaucoma surgery, commonly known as MIGS, represents a significant advancement in treating this condition. These IOP-lowering procedures use microscopic devices and tiny incisions to reduce intraocular pressure with a generally lower risk profile than traditional glaucoma surgery. MIGS procedures have grown significantly over the past decade, reflecting widespread confidence in their safety and effectiveness.

Traditional glaucoma surgery — such as trabeculectomy and tube shunts — typically involves larger incisions and generally carries a higher risk profile. MIGS achieves moderate IOP reduction with a generally better safety profile, making it a preferred option for many patients with mild to moderate disease.

At Washington Eye Institute, our glaucoma specialists use MIGS to help patients preserve their vision while minimizing surgical trauma. Serving the Washington, DC metro area with locations in Greenbelt, Rockville, and Cumberland, Maryland, our team provides access to advanced glaucoma treatments for patients across Montgomery County, Prince George's County, Allegany County, and surrounding communities including College Park, Bethesda, Silver Spring, Gaithersburg, Bowie, Lanham, and Potomac.

Is MIGS the Right Choice for Your Glaucoma?

MIGS procedures are ideal for patients with mild to moderate open-angle glaucoma who want to reduce their dependence on daily eye drops. These glaucoma procedures can also be combined with cataract surgery for a comprehensive approach to both conditions.

Combining MIGS with cataract surgery is one of the most common approaches, allowing patients to address both elevated IOP and lens clouding in a single visit. This combined procedure may reduce overall recovery time and the number of separate surgeries needed. MIGS can also be performed as a standalone IOP-lowering procedure for patients who do not need cataract surgery.

Washington Eye Institute manages early to advanced glaucoma. While MIGS is well suited for mild to moderate cases, patients with more advanced disease may require traditional surgical approaches in addition to or instead of MIGS. Your glaucoma specialist will recommend the best treatment path based on your individual condition.

As with any surgical procedure, MIGS carries some risks, which may include temporary eye pressure changes, mild inflammation, or the need for additional treatment. However, MIGS procedures generally have a lower risk profile compared to traditional glaucoma surgery. While MIGS can help prevent further vision loss, damage already caused by glaucoma cannot be reversed, making early detection critical.

Your glaucoma specialist at Washington Eye Institute will evaluate your condition, review your medical history, and discuss whether MIGS is the right treatment option for your needs. MIGS procedures are performed at the Washington Eye Surgery Center, the practice's ambulatory surgery center located at the Rockville office (14995 Shady Grove Rd Suite 110). Call 301.800.7490 to schedule your consultation.

Many of our MIGS patients experience meaningful IOP reduction and are able to decrease or eliminate their glaucoma medications after surgery.

Featured Treatment

Minimally Invasive Glaucoma Surgery (MIGS)

MIGS procedures use microscopic devices and tiny incisions to create or enhance drainage pathways in the eye, improving the flow of fluid (aqueous humor) out of the eye and lowering intraocular pressure. Performed during a brief outpatient procedure, these techniques offer a safer alternative to traditional glaucoma surgery.

Often combined with cataract surgery, MIGS procedures take just minutes and offer patients a safe, effective way to reduce their dependence on glaucoma eye drops while protecting their optic nerve from further damage.

How a MIGS Procedure Works

1
Evaluation & Imaging

Your surgeon performs a comprehensive eye exam and advanced imaging to map the drainage pathway.

2
Numbing & Preparation

Your surgeon applies numbing drops (topical anesthesia) to ensure your comfort throughout the brief procedure.

3
Micro-Device Placement

Your surgeon places the micro-device in the trabecular meshwork (the eye's natural drainage tissue) through a tiny corneal incision.

4
Pressure Monitoring

Post-operative IOP is monitored closely to ensure optimal pressure reduction and healing.

What to Expect After MIGS

1
Rapid Recovery

Most patients typically return to normal activities within a few days. Some patients may experience mild eye irritation or light sensitivity that generally resolves quickly.

2
Follow-Up Visits

Your doctor will schedule follow-up visits to monitor healing, check your eye pressure, and assess how well the procedure is working.

3
Medication Adjustment

Many patients are able to reduce their glaucoma eye drops after surgery. Your doctor will adjust your medication plan based on your post-operative IOP levels.

4
Ongoing Monitoring

Glaucoma requires lifelong monitoring. Regular check-ups help ensure your IOP remains well controlled and your optic nerve stays healthy.

Frequently Asked Questions

What does MIGS stand for?

MIGS stands for Minimally Invasive Glaucoma Surgery. It refers to a group of surgical procedures that use tiny incisions and microscopic devices to lower eye pressure with less risk and faster recovery than traditional glaucoma surgery.

Is MIGS painful?

Most patients report little to no pain during a MIGS procedure. The surgery is performed under topical or local anesthesia, and any post-operative discomfort is generally mild and typically resolves within a few days. Your doctor will provide guidance on managing any soreness after the procedure.

Can MIGS cure my glaucoma?

Studies show MIGS is effective at reducing IOP in many patients, but it does not cure glaucoma. Glaucoma is a chronic, progressive condition, and ongoing monitoring is necessary even after a successful procedure. To learn more about long-term management, visit our page on whether glaucoma can be cured.

Is MIGS covered by insurance?

MIGS procedures may be covered by insurance, especially when combined with cataract surgery. Coverage varies depending on your plan and individual circumstances. We recommend contacting Washington Eye Institute at 301.800.7490 to discuss coverage and costs for your specific situation.

Will I still need eye drops after MIGS?

Many patients are able to reduce the number of glaucoma eye drops they use after a MIGS procedure, and some patients can stop using drops entirely. However, this varies from patient to patient. Your doctor will adjust your medication plan based on your post-operative eye pressure levels.

How do I know if I am a candidate for MIGS?

The best way to find out is through a comprehensive glaucoma evaluation. Candidates typically have mild to moderate open-angle glaucoma and may also have cataracts that need treatment. Factors such as your glaucoma risk factors, current medications, and the severity of your condition will all be considered. Call Washington Eye Institute at 301.800.7490 to schedule an appointment.

How long does a MIGS procedure take?

Most MIGS procedures take between five and fifteen minutes to perform. When combined with cataract surgery, the total surgical time is still relatively short. The entire visit, including preparation and a brief observation period, typically lasts a few hours.
