The trabeculectomy surgery has persisted for a century because, though it has its challenges, it certainly can work to lower intra-ocular pressure for our glaucoma patients. The use of trabeculectomy has decreased somewhat due to an uptake in MIGS procedures (minimally-invasive glaucoma surgery) and competition from seton tube surgery. This is a relatively easy surgery to perform and all resident surgeons in training should make an effort to learn it. This video shows a combination of phaco plus trabeculectomy. Many years ago these were done via the same incision (superior scleral tunnel) and that still works well, however many surgeons now prefer to do a two site approach with a temporal corneal phaco incision and the superior trabeculectomy.
