All captured images were required to focus on the posterior capsular opening area (PCOA) and visual axis transparent area (VATA) (Figure 1).
(A): The optic diameter of the intraocular lens (IOL) was marked (yellow line), and the distance (pixelated yellow line) was measured. The original image magnification scale was obtained through the distance in pixels/known distance (the optic diameter of the IOL). (B): The contour of the posterior capsular opening area was marked using a pointer. The original area (mm2) was then calculated using the scale included in the Image J software.

The original area was calculated by the software (Figure 2).
