Surgery: Xen Implant using Transconjunctival Approach

This video demonstrates placement of a Xen implant using an external approach transconjunctivally to enhance supra-Tenon’s placement. To ensure adequate length of the Xen implant within the subconjunctival space, pull the injector back by 2mm from the scleral entry site as the slider is advanced forward. This typically leaves approximately 3mm of the Xen subconjunctival, 2mm intrascleral and 1mm in the anterior chamber. Both “ab-interno” and “transconjunctival ab-externo” Xen placement may have a place in surgical approaches.

Surgeon: Dr. Ike K. Ahmed, University of Toronto, Canada
