Glaucoma Stents

Who is suitable for MIGS?

MIGS procedures are generally considered suitable for patients with mild to moderate open-angle glaucoma, the most common form of glaucoma. They may also be considered for patients who haven't responded well to medications or laser treatments but don't yet require more invasive surgical options.

Benefits of MIGS

• Minimally Invasive: MIGS procedures are less invasive than traditional glaucoma surgeries, which usually involve larger incisions and more tissue manipulation. This leads to quicker recovery times and reduced risk of complications.
• Preservation of Conjunctiva: Unlike some traditional surgeries that may require the removal of conjunctival tissue (the thin membrane covering the white part of the eye), MIGS procedures generally avoid extensive conjunctival manipulation, which can help preserve the conjunctiva for potential future treatments.
• Lower Risk Profile: MIGS procedures are associated with a lower risk of complications such as infection, hypotony (very low eye pressure), and prolonged inflammation.
• Faster Recovery: Patients who undergo MIGS procedures typically experience shorter recovery times and can often return to normal activities sooner than with traditional surgeries.
• Reduced Dependence on Medications: MIGS procedures may help reduce the need for glaucoma medications in some patients, potentially improving their quality of life and reducing medication-related side effects.
• Decreased Intraocular Pressure (IOP): The primary goal of glaucoma treatment is to lower IOP to prevent optic nerve damage. MIGS procedures can effectively reduce IOP in many patients.

Types of Glaucoma Stents

There are several types of glaucoma stents used in MIGS procedures. Some of the common ones include:

• iStent: A small titanium stent is inserted into Schlemm's canal, enhancing aqueous outflow.
• Hydrus: A micro stent implanted to open and support Schlemm's canal and provide a larger pathway for aqueous humour drainage.

Glaucoma Stents (MIGS) Procedure

• Anaesthesia: Most MIGS procedures are performed under local anaesthesia. This means you'll be awake but won't feel pain in the eye area. Some procedures might require general anaesthesia.
• Procedure Steps: The specific steps will vary depending on the type of MIGS procedure. Generally, a small incision is made, and the stent or device is implanted to create a new drainage pathway for the aqueous humour.
• Duration: MIGS procedures are usually relatively short, often taking 15 to 30 minutes.
