Biomicroscopy and AS-OCT trajectory of the Preserflo MicroShunt.Fig. 2.I. Patient 1. a. Biomicroscopy of the left eye, the microshunt is located superiorly, no corneal edema. b. AS-OCT visualizing a horizontal and corneal trajectory of the microshunt. The intracameral portion of the microshunt is very short.

Fig. 2.II. Patient 2. a. Biomicroscopy of the left eye, the microshunt is located nasal-superiorly, no corneal edema. b. AS-OCT visualizing a satisfactory trajectory of the microshunt in the cornea and a suficient portion of the shunt in the anterior chamber, far from the cornea and the iris. We must note a hyperreflective structure between the shunt and the endothelium that can be an inflammatory reaction. We can also see a swollen intracameral part of the shunt (*).
