While the primary method for implantation is via ab interno approach, it is also possible to implant the device ab externo. This technique paper details the surgical steps for closed conjunctival implantation of the Gel Stent and provides surgical pearls for enhancing outcomes.Keywords: XEN Gel Stent, glaucoma, filtration surgery, ab interno, ab externo, transconjunctival implantation
