Glaucoma surgery: how to manage failing MIGS

Glaucoma surgery is very effective at achieving good and long‐term pressure control with an acceptable safety profile. There are, however, patients for whom a previously successful procedure starts to fail. Minimally invasive glaucoma surgery (MIGS) techniques are becoming widely used for mild to moderate glaucoma. These techniques have an improved safety profile compared to more traditional filtration surgery, but there are still occasions when these techniques fail. This presentation, using surgical videos, personal experience and evidence from the literature, will aim to discuss a range of the most recently used MIGS techniques, including the iStent, Cypass microstent, endocyclophotocoagulation and Xen gel stent. The presentation will cover patient selection, complications, techniques to improve success and device misplacement.
