*3.4.3 Surgical technique*

After cataract surgery, the side port corneal incision is used in order to introduce viscoelastic and the microcatheter towards the nasal angle [10]. A side port incision for the iTrack™ microcatheter is created approximately 90° away from de nasal drainage angle, wich is inserted into the AC with te catheter tip guided towards the nasal angle [10]. A 25 G needle or a Cystotome® is used to perform a micro-goniotomy in the nasal TM under visualization using a gonioprism [9]. The microcatheter is held by a micro-surgical forceps and the SC is intubated inserting the catheter through the goniotomy until complete the circumferential intubation of SC 360° [10]. After that, the catheter is slowly withdrawn while infusing viscoelastic every clock hour [9]. Finally, the catether is removed, the viscoelastic is washed, and the corneal incision is sealed by hydrating the stroma [10].
