Minimally Invasive Glaucoma Surgery: Where We Are, and What the Future Holds

Purpose of Review Minimally invasive glaucoma surgery, or MIGS, has revolutionized the glaucoma surgical space in the past 15 years. The high safety profile and moderate efficacy of MIGS has enabled earlier surgical intervention for glaucoma, providing safe and sight-saving care sooner. This review aims to examine the latest evidence on available devices and techniques. Recent Findings Trabecular outflow remains a mainstay for MIGS targets, with distal outflow enhancement and alternative drainage pathways showing efficacy. Comparisons of various MIGS devices and techniques are emerging, which will enable glaucoma surgeons to better design individualized care for their patients. While no single MIGS has emerged as significantly superior to others; some MIGS may be better suited for some types of glaucoma, however. Minimally invasive glaucoma surgeries provide safe and effective alternatives to traditional filtering glaucoma surgeries in many patients. The high safety profile of MIGS enable earlier surgical interventions, which can improve visual outcome and patients' quality of life. There is an abundance of evidence showing the efficacy and safety of various MIGS, with innovations continuing to advance the surgical treatment of glaucoma.
