Minimally invasive glaucoma surgery (MIGS) refers to a class of surgical techniques designed to lower intraocular pressure (IOP) in glaucoma patients using less invasive methods than traditional surgery. MIGS is typically performed through micro-incisions and involves minimal disruption to the surrounding ocular tissue. These procedures aim to improve fluid drainage from the eye and are often performed in patients with mild to moderate open-angle glaucoma.
Key Benefits of MIGS
Minimally invasive glaucoma surgery represents a significant advancement, offering a safer and more efficient pathway for managing glaucoma, particularly for patients with mild to moderate disease. Key benefits include:
Safer Profile with Lower Risk of Complications
MIGS procedures have a significantly lower incidence of serious complications such as hypotony (abnormally low eye pressure), infection, and bleb-related issues compared to traditional glaucoma surgeries like trabeculectomy.
Faster Recovery Time
Most MIGS procedures are conducted as day surgeries, allowing patients to return to normal activities more quickly than those undergoing conventional surgery.
Preservation of Eye Structure
MIGS techniques are specifically designed to minimise trauma to the conjunctival and scleral tissue. This not only supports a faster recovery but also preserves more options for future surgical interventions should they be needed.
Compatibility with Cataract Surgery
A key advantage of MIGS is its ability to be safely combined with cataract extraction. This offers the dual benefit of simultaneously addressing both visual improvement and intraocular pressure control in a single surgical session.
Who Should Consider MIGS?
Minimally invasive glaucoma surgery is typically recommended for individuals with mild to moderate open-angle glaucoma. It is especially recommended for those undergoing cataract surgery or seeking to reduce their dependence on long-term medication.
However, it may not be appropriate for individuals with advanced or aggressive forms of glaucoma where a greater and more sustained reduction in intraocular pressure is required. In such cases, traditional surgical approaches may be more effective. Long-term outcomes of MIGS are still being evaluated, and for some patients, additional or alternative procedures may eventually be necessary.
At Eye & Glaucoma Surgeons, Dr Daniel Su Hsien Wen carefully assesses each case to determine if MIGS aligns with a patient’s clinical needs and long-term vision goals. If you have been diagnosed with glaucoma and are exploring surgical options, schedule a consultation with our surgeon to find out if MIGS is the right choice for you.
