The Relationship between Anterior Chamber Angle and Intraocular Pressure Early after V4c Implantable Collamer Lens Implantation

Figure 1

The indication of parameters measured by AS-OCT. Note: AOD: the vertical distance from the posterior surface of the cornea to the iris surface, with a 500 µm or 750 µm distance to the scleral spur; TIA: a vertical line was drawn from the cornea to the iris, and the TIA was the angle formed by the recess, cornea point, and iris point, with the recess as the vertex, and the cornea point was 500 µm or 750 µm from the scleral spur. Green line: the indication of a certain parameter. Abbreviations: AS-OCT: anterior segment optical coherence tomography, AOD: angle opening distance, and TIA: trabecular-iris angle.
