*3.3.1 Definition*

It is a sectoral (90°) ab-interno MIGS technique in which the TM and the internal wall of the canal are bundled (similar to the procedure performed with the trabectome) with a device that is inserted into the TM and consists of a ramp in the distal end that, as we advance in the cut, raises the TM tissue and directs it towards 2 blades at the ends of the ramp that allow the cutting and extraction of this tissue [5].
