Quiz: Minimally Invasive Glaucoma Surgery (MIGS) Patient

The patient in this video is undergoing one form of minimally invasive glaucoma surgery (MIGS). Typical features of all MIGS procedures include an ab interno approach through a clear corneal incision which is conjunctival sparing, minimally traumatic to the target tissue, high safety profile, and a rapid recovery. There are many types of MIGS procedures, broadly including the following four categories: cyclodialysis, goniotomy, goniotomy (stent), and filtering (bleb). This patient is undergoing a goniotomy-type MIGS procedure using the Kahook dual blade. In this case, it is being performed at the same time as cataract/IOL surgery, just after implantation of the IOL. With this form of MIGS, Schlemm’s canal is unroofed by excising (Kahook dual blade) or ablating (Trabectome) a section of the trabecular meshwork. Please watch this video before taking the quiz:
