Description
Summary:Purpose: Interest in micro-invasive glaucoma surgery (MIGS) has exploded over the last 8 years with an increase in MIGS procedures of at least 400% in the United States, according to Medicare data. MIGS is an umbrella term that can cover many different types of surgeries. This review focuses on peer-reviewed evidence for Trabectome ® , iStent inject ® , Kahook Dual Blade ® , XEN ® Gel Stent, and Hydrus ® . Methods: We present key recent studies evaluating the efficacy and safety of MIGS in various types of glaucoma patients with different stages of disease. Conclusion: We conclude that MIGS is generally safe and efficacious, although only some MIGS have been studied through randomized clinical trials. When comparing and contrasting the different MIGS procedures, large prospective studies are not yet the norm. High-quality large prospective studies involving MIGS will be an important next step as ophthalmologists decide how to incorporate MIGS into their surgical armamentarium.
