What is Minimally Invasive Glaucoma Surgery (MIGS)? - Glaucoma Glossary

MIGS encompasses a diverse group of micro-incisional surgical procedures and implantable micro-stents designed to lower IOP safely, typically performed concurrently with cataract surgery.

What it means for the patient

MIGS procedures involve inserting tiny microscopic devices into the eye's natural drain to help bypass clogs. They are much safer and heal much faster than traditional major glaucoma surgeries, though they may achieve slightly less pressure reduction.

Clinical significance

MIGS aims to bridge the gap between pharmacotherapy and invasive penetrating surgeries (trabeculectomy). Devices like the iStent, Hydrus, or Xen Gel Stent offer excellent safety profiles for mild-to-moderate POAG by utilizing Schlemm's canal or forming subconjunctival blebs.

How it is tracked

MIGS surgeries are tracked via the clinical roadmap, visualizing their long-term efficacy in eliminating patient drop-dependency.
