AS-OCT analysis (CASIA2, Tomey). Iris implants were placed on the anterior layer of the iris, exceeding the pupil border and contacting with the irido-corneal angle. The green vertical line represents the pupillary axis. By using the calliper system provided by CASIA2, the horizontal (0°-180° axis, A and D) and vertical (90°-270° axis, B and E) distance between this axis and the internal edges of the central hole of the iris implants could be measured. On each axis, 2 segments were measured (nasal/temporal, superior/inferior), and sustracting the longest of them from the central hole radius, the magnitude of the decentration on every direction was determined. Iris-trabecular contact (ITC) analysis in the right eye (E) and the left eye (F): blue area shows the contact of the iris with the trabecular meshwork, confirming some areas of peripheral anterior synechiae in both eyes (SS: scleral spur, red line; AR/EP: trabecular iris endpoint contact marked by an observer analyzing the image, green line)
