Micro-invasive glaucoma surgery (MIGS) is a group of minimally invasive procedures designed to lower eye pressure in patients with glaucoma. Unlike traditional glaucoma surgery, MIGS uses tiny incisions and microscopic instruments to improve the eye’s natural drainage system. Many MIGS procedures can be performed during cataract surgery, allowing patients to address both cataracts and glaucoma in a single procedure.
Quick Takeaways
- MIGS helps lower intraocular pressure by improving fluid drainage from the eye.
- Many MIGS procedures can be performed during cataract surgery.
- MIGS typically involves smaller incisions and a faster recovery compared with traditional glaucoma surgery.
- Glaucoma often develops without noticeable symptoms, making medical eye exams important.
- An ophthalmologist can determine whether MIGS is appropriate based on your type and severity of glaucoma.
How Does MIGS Treat Glaucoma?
Glaucoma damages the optic nerve, often due to increased eye pressure caused by poor fluid drainage. Over time, this damage can lead to permanent vision loss. According to the American Academy of Ophthalmology, glaucoma is one of the leading causes of blindness worldwide.
MIGS procedures work by improving the eye’s natural drainage pathways to help reduce pressure and protect the optic nerve. Common MIGS techniques include canaloplasty and goniotomy, which target the eye’s drainage system.
Newer approaches continue to expand treatment options for glaucoma patients. AlloFlo® is an emerging suprachoroidal glaucoma procedure designed to create an additional pathway for fluid drainage using a small biotissue implant. This minimally invasive approach is being studied as part of the continued advancement of glaucoma care and may be an option for select patients based on their individual eye health.
At DLV Vision, patients often ask whether glaucoma surgery requires a lengthy recovery. In many cases, MIGS provides a less invasive treatment option that allows patients to return to normal activities more quickly compared with traditional glaucoma procedures.
Who Is a Candidate for MIGS?
MIGS may be recommended for patients with mild to moderate glaucoma, especially those who are undergoing cataract surgery. Candidates may include patients who:
- Have open-angle glaucoma
- Need additional eye pressure control despite using glaucoma medications
- Want to reduce their dependence on eye drops
- Are already planning cataract surgery
A comprehensive evaluation is needed to determine whether MIGS is the right choice. The DLV Vision team reviews eye pressure, optic nerve health, and visual field results before recommending treatment.
What Should You Expect During Recovery?
Recovery after MIGS is typically faster than traditional glaucoma surgery, but patients may experience temporary blurry vision or mild discomfort during the first few days.
A small amount of blood in the front of the eye may occur after treatment and typically clears on its own within a few weeks. Patients should continue their glaucoma medications unless instructed otherwise by their ophthalmologist. Follow-up visits help monitor healing and determine whether medication adjustments are needed.
If you live in Ventura, Westlake Village, Camarillo, Simi Valley, Thousand Oaks, Oxnard, or Newbury Park, you can request a glaucoma consultation at DLV Vision or call (805) 987-5300.
When Should You See an Eye Doctor About Glaucoma?
Because glaucoma often progresses without symptoms, early detection is essential. Schedule a medical eye exam if you have a family history of glaucoma, diabetes, elevated eye pressure, vision changes, or difficulty seeing in your peripheral vision.
MIGS cannot cure glaucoma or restore vision already lost, but it can help lower eye pressure and slow disease progression. Your ophthalmologist can determine the best treatment approach based on your specific needs.
