Background: Minimally invasive glaucoma surgeries are a breakthrough and have added significantly to the glaucoma surgical armamentarium in the recent past. Angle surgeries, in particular, using the trabecular bypass micro-stents, are one of the safest ones for mild to moderate primary open-angle glaucoma. These can be safely done along with the cataract surgeries. Purpose: The purpose of this video is to demonstrate the exact technique of performing iStent inject W in the angle using intraoperative gonioscopy and to help the audience with tackling suboptimal implantation of the iStent intra-operatively. Synopsis: This video demonstrates how to perform the intraoperative gonioscopy, explains about the lenses used for the procedure, and describes the exact technique for performing the iStent procedure. This video describes in detail the iStent inject device and its injector system. It also explains in detail about the different types of intraoperative gonioscopy lenses that can be used to perform the angle procedures. The video describes a step-by-step procedure to implant an iStent in the angle and also to check its efficacy using trypan blue injection. Further, it also explains to the audience about the corrective measures in case there is under-implantation, over-implantation, or wrong implantation of the stent. Highlights: The appropriate technique of performing intraoperative gonioscopy for obtaining a clear view of angles and exact demonstration of the steps of iStent inject implantation, along with tips to avoid problems at each step are the major highlight of this video. Further, it also demonstrates examples of suboptimal implantation and their corrections. Video Link: https: //youtu. be/cVW2kTVSXc
