Minimally invasive glaucoma surgery
Minimally invasive glaucoma surgery (MIGS) refers to a group of procedures aimed at treating glaucoma while minimizing trauma and promoting faster recovery compared to traditional surgeries. In addition, surgeons often combine these procedures with cataract surgery or perform them as standalone interventions, offering a safer and less invasive option for glaucoma patients.
How MIGS Works
MIGS procedures lower intraocular pressure (IOP) by improving the outflow of aqueous humor, the fluid circulating within the eye. By reducing IOP, these procedures help slow down or halt glaucoma progression, thereby preserving vision. As a result, patients experience a significant improvement in their quality of life, with fewer symptoms and better eye health.
The Hydrus MicroStent
Alcon’s Hydrus MicroStent is a small device made of nitinol, implanted in the eye during cataract surgery. Specifically, doctors use this device for patients with mild to moderate primary open-angle glaucoma. The FDA approved it under the MIGS category, creating a “trabecular meshwork bypass.” Consequently, the Hydrus MicroStent forms a new pathway for aqueous humor, bypassing the blocked or malfunctioning meshwork. This improvement in drainage helps lower intraocular pressure.
Benefits of MIGS
MIGS procedures are generally safer and less invasive than traditional glaucoma surgeries like trabeculectomy or tube shunt implants. Moreover, doctors typically perform them on patients with mild to moderate glaucoma, aiming to reduce the need for long-term medication. As a result, many patients experience immediate improvements, including noticeable reductions in eye pressure and enhanced comfort.
Risks and Considerations
As with any surgery, MIGS carries risks and potential complications. Therefore, patients should consult an ophthalmologist or glaucoma specialist to determine the best treatment approach based on their specific circumstances and the type and severity of their glaucoma. Ultimately, early intervention with MIGS can prevent further damage to the optic nerve and help maintain long-term vision.
