Exploring Cutting-Edge Minimally Invasive Glaucoma Surgery Techniques

Glaucoma is a serious eye condition that affects millions of people worldwide, often leading to vision impairment or blindness if left untreated. Thankfully, advancements in medical science have led to the development of minimally invasive glaucoma surgery (MIGS) techniques, offering patients a safer and more effective way to manage their condition. In this blog post, we will explore four exciting MIGS procedures: iStent, goniotomy with Kahook’s dual blade glide, Bent ab interno needle gonioectomy, and suture GATT. These innovative approaches provide new hope for glaucoma patients seeking to preserve their vision and quality of life.

1.iStent: A Tiny Device with a Big Impact
iStent is a groundbreaking MIGS procedure that involves implanting a micro-sized device into the trabecular meshwork, a drainage system within the eye. This small stent creates a new drainage pathway, allowing excess aqueous humor to flow out of the eye, thereby reducing intraocular pressure (IOP). iStent is typically performed during cataract surgery, making it a convenient option for patients with both glaucoma and cataracts. Its minimally invasive nature means shorter recovery times and reduced reliance on glaucoma medications.

2.Goniotomy with Kahook’s Dual Blade Glide: Cutting-Edge Precision
Goniotomy has been a traditional surgical approach for managing glaucoma. However, recent advancements, such as Kahook’s dual blade glide, have transformed this procedure into a more efficient and less invasive option. Kahook’s dual blade glide uses a specialized tool that allows surgeons to make precise incisions in the trabecular meshwork, improving aqueous humor drainage. This technique has demonstrated impressive results in lowering IOP and reducing the need for glaucoma medications.

3.Bent Ab Interno Needle Gonioectomy: A Delicate Touch
The Bent ab interno needle gonioectomy is a relatively new MIGS procedure that focuses on enhancing the natural drainage pathways within the eye. During the procedure, a bent needle is inserted into the eye through a tiny incision, allowing surgeons to carefully remove obstructing tissue and improve the outflow of aqueous humor. This approach is considered minimally invasive, as it avoids the need for large incisions, resulting in reduced surgical trauma and quicker recovery times.

4.Suture GATT: A Promising Technique
The Glaucoma Angle Surgery with Suture Technique (GATT) is an innovative MIGS procedure designed to improve aqueous humor outflow. Unlike traditional trabeculectomy, GATT involves creating a microchannel through the trabecular meshwork and sclera, allowing for more controlled IOP reduction. Suture GATT is particularly advantageous because it doesn’t require the use of a permanent implant or drainage device. Instead, a suture is used to maintain the microchannel, making it reversible if needed.
Benefits of MIGS Procedures

MIGS procedures offer several advantages over traditional glaucoma surgeries, including:

1.Minimally Invasive: MIGS techniques use small incisions, reducing the risk of complications and promoting faster recovery.
2.Lower IOP: These procedures effectively lower intraocular pressure, the primary goal in glaucoma management.
3.Reduced Medication Dependency: Many patients can reduce their reliance on glaucoma medications after undergoing MIGS.
4.Compatibility with Cataract Surgery: Some MIGS procedures can be performed concurrently with cataract surgery, streamlining treatment for patients with both conditions.


Minimally invasive glaucoma surgery techniques like iStent, goniotomy with Kahook’s dual blade glide, Bent ab interno needle gonioectomy, and suture GATT represent exciting breakthroughs in the field of ophthalmology. These procedures offer new hope for glaucoma patients by providing effective and less invasive options for managing intraocular pressure and preserving their vision. If you or a loved one are facing the challenges of glaucoma, be sure to consult with an experienced ophthalmologist to explore these cutting-edge treatment options.
