The Revolutionary iStent: A Minimally Invasive Solution for Glaucoma

Effective glaucoma treatment is critical for preserving a patient’s vision. Glaucoma is chronic and progressive, and without proper treatment, it robs patients of their vision. Globally, glaucoma is the leading cause of blindness, but it is possible to slow its progression significantly.  

One minimally invasive glaucoma surgery (MIGS) that’s revolutionizing glaucoma treatment is the iStent. Here’s a look at the iStent, how it treats glaucoma, and how to determine if it’s right for you.  

What Is the iStent?  

The iStent is a tiny, implantable device designed to alleviate the intraocular pressure (IOP) caused by glaucoma. Shaped like a microscopic stent, it’s made of biocompatible material and is so small that it qualifies as the tiniest medical device currently in use. The primary purpose of the iStent is to facilitate the drainage of fluid from the eye, addressing the root cause of the IOP that can damage the optic nerve and rob glaucoma patients of their vision.  

How Does the iStent Treat Glaucoma?  

To understand how the iStent treats glaucoma, it’s critical to know how glaucoma impacts the eyes and a patient’s vision. Glaucoma is characterized by a rise in IOP due to poor drainage of the aqueous humor (the fluid that nourishes the eye).  

When IOP increases, the pressure can damage the optic nerve. As the optic nerve is damaged, vision impairment occurs. Without treatment, vision loss expands, potentially leading to blindness.  

The iStent treats glaucoma by creating a pathway for fluid. During a MIGS procedure, the iStent is positioned in the trabecular meshwork in a drainage channel in the eye. Once in place, the iStent allows the natural drainage system in the eye to work more effectively. In turn, IOP is reduced, and that prevents or reduces further optic nerve damage.  

The iStent is positioned during cataract removal surgery, allowing for fewer total incisions. Only local anesthesia is required, and the procedure itself is painless.  

Additionally, the iStent is considered a long-term solution for glaucoma patients. It also reduces the need for further treatments, allowing patients to rely less on eye drops to keep IOP at an appropriate level.  

Is iStent Right for You?  

Generally, the iStent is a viable treatment for patients with mild-to-moderate open-angle glaucoma currently using eye drops but who aren’t achieving the desired IOP reductions. Additionally, it’s only positioned in conjunction with cataract surgery.  

However, whether you’re a good candidate for the iStent may depend on other factors. As a result, it’s critical to speak with your eye care provider about your glaucoma, the effectiveness of your current treatment, and whether the iStent is potentially the right choice.

Unlike traditional methods, LACS utilizes femtosecond lasers for critical steps in the surgery, including corneal incisions, capsulotomies, and lens fragmentation.

Before the surgery, detailed imaging of the eye is conducted using technologies like optical coherence tomography (OCT). This imaging provides a 3D eye map, allowing the surgeon to visualize the cataract and other structures more accurately.

The precision offered by lasers in creating incisions and performing delicate procedures has significantly enhanced surgical outcomes. Surgeons can now customize incision patterns, ensuring optimal wound healing and reducing astigmatism. Capsulotomies, the process of creating an opening in the lens capsule, are executed with unparalleled accuracy, contributing to improved IOL positioning and stability.

The femtosecond laser creates corneal incisions, the entry points for surgical instruments. These incisions are more precise than those made manually, promoting quicker healing and potentially reducing astigmatism. The laser is employed to make a circular opening in the front portion of the lens capsule, creating an access point for cataract’s removal. The precision of the laser in this step contributes to better centration of the intraocular lens. The femtosecond laser also fragments the cataractous lens into smaller, easily removable pieces. This can reduce the amount of ultrasound energy required during the surgery, potentially minimizing the risk of complications.

Incorporating robotics into cataract surgery further amplifies precision and safety. Robotic systems allow surgeons to control specialized instruments with utmost accuracy, navigating the complexities of the eye with finesse. The research states, “Robotic assistance can help overcome biologic limitations and improve our surgical performance.” Robotics technology minimizes the risk of complications and ensures the surgical reproducibility of results, setting a standard for excellence in surgical outcomes.

Exploring Minimally Invasive Glaucoma Surgery (MIGS)

Glaucoma is a chronic and progressive eye condition that’s also the leading cause of blindness in the world. Damage occurs as intraocular pressure (IOP) builds, which harms the optic nerve, causing irreversible vision loss. Traditional glaucoma treatments usually involve topical medications or laser treatments, the latter of which are associated with challenges like complications, long recovery times, and significant follow-up requirements.  

Fortunately, newer procedures are proving effective at addressing IOP in glaucoma patients, and they can involve less risk when compared to some traditional alternatives. Minimally invasive glaucoma surgery (MIGS) is a cutting-edge approach that’s proving highly effective, and it’s potentially safer than some other forms of treatment. Here’s what you need to know about MIGS.  

What Is Minimally Invasive Glaucoma Surgery?  

MIGS is a group of glaucoma surgeries that use minimally invasive approaches to reduce IOP. Typically, they involve a small incision and subsequent procedures to improve fluid drainage, leading to far less intraocular pressure.  

While MIGS can’t reverse any damage caused by glaucoma, the treatments can slow or prevent progression. The procedures typically decrease IOP substantially over periods of up to two years. Plus, they can reduce a patient’s need for glaucoma eye drops, making the condition easier to manage daily. 

Types of MIGS  

There are several MIGS procedures currently available. Here is a brief overview of them:  

  • Ab-Interno Canaloplasty (ABiC): A MIGS procedure that uses a microscopic incision and the insertion of a catheter into the drainage canal to inject a viscoelastic substance that breaks down blockages and adhesions to improve fluid drainage  
  • CyPASS: A MIGS procedure involving an implanted device that’s positioned in the suprachoroidal space to enhance fluid outflow  
  • Gonio-Assisted Transluminal Trabeculotomy: A MIGS procedure similar to ABiC that’s particularly well-suited to younger patients with juvenile glaucoma  
  • iStent: A MIGS procedure using a small implant that’s placed in the drainage angle to improve fluid outflow  
  • Trabectome: A MIGS procedure for treating open-angle glaucoma that involves a small incision and a specialized tissue debris-removal tool to address fluid drainage blockages.  

The Benefits of MIGS  

MIGS procedures offer patients an array of benefits. Generally, MIGS is far safer than traditional glaucoma surgery, using smaller incisions and coming with a reduced risk of complications. Each of the MIGS procedures also minimally alters normal anatomy and instead focuses on augmenting physiological systems to improve outflow.  

With a MIGS procedure, IOP is typically reduced significantly, though the exact amount can vary. In many cases, patients can reduce their use of eye drop medications after a MIGS procedure. Recovery is also far quicker when compared to many traditional surgical alternatives, resulting in less downtime for patients.  

Is MIGS Right for You?  

Generally, MIGS are potential treatments for patients with mild or moderate glaucoma who either aren’t getting positive results with topical medications or who don’t tolerate those treatments well. The use of the implants reduces the need for topical medications, making them a strong choice in situations where medications prove ineffective or lead to undesirable or hard-to-manage side effects.  

However, only an eye care provider can determine if you’re a good candidate for MIGS. Additionally, there are several MIGS procedures available, and some may better suit your situation than others.
