Minimally invasive glaucoma surgery includes different devices which provide a less invasive and safer means of reducing intraocular pressure. The XEN Gel Stent (Allergan Inc., CA) is an ab interno procedure which creates a subconjunctival drainage pathway. It is a new surgical device and there is a paucity of data on complications and their management. We report a clinical case of a leaking bleb after XEN surgery managed by bleb revision, conjunctival suturing, and XEN replacement.
