MINIMALLY INVASIVE GLAUCOMA SURGERY (MIGS)





 

What is the eye procedure, MIGS?

Minimally invasive glaucoma surgery, better known as MIGS, is a modern procedure that utilises microsurgical equipment to lower high intraocular pressure and treats glaucoma. MIGS reduces eye pressure using techniques and modern devices that are safer and faster to perform than conventional surgery. MIGS is proven to offer a faster recovery than most interventional procedures. In addition, clinical studies indicate that MIGS minimises eye pressure to prevent vision loss from glaucoma and reduces the use of prescription eye drops

How do we perform MIGS?

MIGS aims to reduce fluid pressure and improve the drainage network in people with mild to moderate glaucoma.

MIGS encompasses several eye procedures to treat glaucoma, which include:

  • Trabecular Micro-Bypass i-Stent is the use of an implantable medical device (stent) made from titanium placed in two regions of the front part of the eye to pump out more ocular fluid through the drainage network.
  • Canaloplasty (i-Track) is a procedure that makes use of a tiny, micro-sized catheter to create a path in the clogged drainage canal (Schlemm's canal). Next, the canal is cleaned of any debris, and a viscoelastic gel is applied. The gel helps widen the canal to reduce the build-up of ocular fluid and minimise eye pressure.
  • Trabectome surgery is a procedure that utilises an electrocautery tool (Trabectome) to remove a portion of the eye's natural drainage network. A larger opening in the meshwork allows more fluid to exit the drainage channel, thus reducing intraocular pressure.
  • Gel XEN stent comprises soft, gel-like material that is surgically implanted in the wall of the eye in the front to remove fluid and pump it out in the area just beneath the conjunctiva.
  • Endocyclophotocoagulation is laser eye surgery that targets ciliary body cells that are responsible for producing ocular fluid. A miniaturised camera is used to examine these cells and decrease their functionality by producing less ocular fluid. A laser helps reduce the cell’s activity and minimise eye pressure. Each eye receives treatment that typically lasts no more than five minutes and successfully treats open and closed-angle glaucoma.
