*3.3.3 Surgical technique*

The patient's head should be turned to the opposite side of the eye to be treated [5]. The corneal incision of cataract surgery is used to inject cohesive viscoelastic and introduce the kahook, which advances through the anterior chamber towards the nasal angle sector, which is visualized by gonioscopy [5]. The tip of the kahook is inserted through the TM into SC, and a cut is made along the TM in a clockwise direction, followed by another cut in an anti-clockwise direction, using the insertion site as a point of attachment reference (**Figure 2(B)**) [5]. The reflux of blood confirms the opening of the SC [5]. Finally, the device is removed, the viscoelastic is washed, and the corneal incision is sealed by hydrating the stroma [5].
