Figure 1 Determination of the navigation implant location of Toric intraocular lens. A: Axial and main incision position; B: The intraoperative navigation system verion system was used to calibrate the position and axis of the main incision before superlactation, and to observe whether the position of manual slit lamp marking was consistent with that before operation; C: Watertight incision and final determination of crystal position and axial accuracy; D: Complete removal of viscous elastic agent before and after crystal removal and accurate alignment of axial direction.
