Purpose: The purpose of this article is to compare whether open-angle glaucoma requiring surgical management can be effectively treated using new minimally invasive surgical devices and techniques versus an old, proven, but problematic invasive surgical procedure.

Method: A PubMed literature search was conducted with the search terms open-angle glaucoma, minimally invasive glaucoma surgery, and trabeculectomy. Twenty-five pertinent articles were retrieved, and they serve as the basis for this clinical review.

Results: Minimally Invasive Glaucoma Surgery (MIGS) was found to offer patients requiring surgical management of open-angle glaucoma an alternative way to reduce intraocular pressure (IOP) over trabeculectomy.

Conclusion: Trabeculectomy has been the standard treatment for open-angle glaucoma requiring surgical management for over fifty years. However, recent advancements have been made that allow less invasive techniques and devices to effectively reduce intraocular pressure and avoid the high complication rate of trabeculectomy. Depending on the degree of reduction of eye pressure required, trabeculectomy may be the only alternative. Further research is needed to determine the long-term efficacy of newer intraocular pressure-reducing devices.
