Gonioscopy Assisted Transluminal Trabeculotomy

The Technique

The SimulEYE model that was developed to practice Ab Interno Canaloplasty (ABiC) with the iTrack device can also be used to practice Gonioscopy Assisted Transluminal Trabeculotomy (GATT). Watch as a 5-0 prolene suture is prepared with low-temp cautery to create a terminal bulb and then introduced into Schlemms canal and advanced using the MST forceps.

The ABiC iTrack Model

This model was designed specifically for the Ellex iTrack device to practice the ABiC procedure. When used in conjunction with the MIGS KIT to simulate head tilt, the angle structures can be visualized with the use of a gonioprism and gel. A pre-placed opening in the pigmented TM allows for placement of the iTrack catheter through a pre-placed side port incision. Advancing the catheter into and along the canal allows visualization of the red blinking light on the outside of the eye. With proper care, this model can be reused multiple times.
