Evolving Surgical Interventions in the Treatment of Glaucoma.

Interventions in the treatment of mild to moderate glaucoma have evolved to include a group of procedures collectively named "Minimally Invasive Glaucoma Surgery (MIGS)." These procedures are less invasive than traditional filtering surgery and setons and offer the benefit of an improved side-effect profile. A review of current published literature has shown that these procedures offer lower intraocular pressure, decrease reliance on topical medications, have no negative effect on refractive outcomes, and can be safely done following failed tube surgery.
