XEN implantation

Webinar Description

Presenter: Chelvin Sng

The XEN Gel Implant is a subconjunctival MIGS device which is implanted ab-interno. Inject the mitomycin C intra-tenon’s at least 5 mm posterior to the limbus. Make a cornea incision in the inferior-temporal cornea with a 20 gauge MVR knife, approximately 1 millimetre anterior to the limbus. Mark the conjunctiva about 2-3 millimetres posterior to the surgical limbus. Insert the injector into the anterior chamber, and with intra-operative gonioscopy, pierce the angle just anterior to Schlemm’s canal. Once the needle has engaged the angle, the gonioscopy lens can be removed, and the slider is moved forward on the injector to push the implant into the subconjunctival space. Ensure that the XEN Gel Implant is free and mobile after implantation.
