From the frontal view of the eye, it is known that the horizontal distance of the cornea appears slightly wider than the vertical distance. This is because the top and bottom of the anterior cornea are slightly overlapped by the sclera. The resulting difference between the horizontal and vertical diameters of the cornea is about 10%, according to relevant references.

Thus, if the measurement was based on a vertical standard, as the commenter pointed out, it would be necessary to adjust the values accordingly; however, in this study, the values were measured based on the horizontal diameter. Nonetheless, in Figure 1, the drawings of the corneal diameter as the reference point were incorrectly marked with vertical distances.

I am very sorry about this error, and I will pay careful attention to prevent this mistake from happening again. I would appreciate it if Dr. Kun Hwang could refer to the author’s previous paper, which involved measurements of the horizontal diameter of the cornea and was used as a reference in the present study (Fig. 1) [2,3].
