Glaucoma is a challenging condition that is the leading cause of irreversible blindness worldwide. For patients requiring surgery, the choices often involve balancing effective intraocular pressure (IOP) reduction with minimizing the risk of complications. However, new advancements in treatment are offering fresh hope. One such innovation is the PRESERFLO™ MicroShunt, a groundbreaking procedure designed to help manage this eye condition effectively. Let’s dive into what the Preserflo Microshunt is and how it can benefit those with glaucoma.

What to Expect from Glaucoma Surgery

Primary open-angle glaucoma, the most common type, needs timely intervention to preserve vision. The Health Canada-approved PRESERFLO™ MicroShunt is a tiny, soft, and flexible stent designed to help your eye drain excess fluid, thereby lowering eye pressure and preventing further vision loss. 

It’s important to note that while PRESERFLO™ MicroShunt can help prevent further vision loss, it cannot restore vision already lost to glaucoma.

How Does the PRESERFLO™ MicroShunt Work?

Normally, fluid circulates in the eye to maintain healthy ocular pressure. In glaucoma, this fluid doesn’t drain properly, leading to a buildup that raises eye pressure and potentially damages delicate eye tissues. The PRESERFLO™ MicroShunt helps by providing a permanent way to drain excess fluid out of the eye.

Benefits 

1. Permanent Solution: This device offers a lasting treatment option for managing glaucoma.
2. Effective IOP Reduction: Clinical studies and real-world experience show that the device consistently lowers IOP to an average of 15 mmHg or less.
3. Less Invasive Procedure: The device is implanted during an outpatient procedure under anesthesia. This procedure is less invasive and typically quicker than traditional glaucoma surgeries.
4. Safety: The procedure has low rates of post-operative interventions, making it a safer choice for many patients.

What to Expect Before Surgery

Before your surgery, your doctor might instruct you to adjust your medications. It’s crucial to follow these instructions carefully and discuss any concerns or questions you might have about the procedure. Make sure to arrange for someone to take you home after the surgery for your safety.

What to Expect After Surgery

In the first week following the surgery, you may experience some temporary symptoms such as:

• Blurry vision
• Eye redness
• Eye swelling

These symptoms should subside as you heal. Your doctor may prescribe eye drops to aid in the recovery process. Avoid rubbing your eye or engaging in strenuous activities, including sports, shortly after the procedure.

Is It Right for You?

The Preserflo Microshunt is a promising option for many glaucoma patients, but it’s essential to have a thorough discussion with your eye specialist. They can evaluate your specific condition and determine if this procedure is the best choice for managing your glaucoma. 

It’s important to note that the Preserflo Microshunt procedure is currently being offered at various specialized eye clinics and hospitals across Canada. It was CE-marked in Europe in 2012 and is pending FDA approval in the USA.
