👨🏻‍⚕️ Dr. Kang Sung-yong, Chief Director:
If we digitally extract these two maps, we can create a difference map.

Looking at this map, you can confirm that only the central part has changed. When surgically correcting myopia in the dominant eye, only the central part is corrected.

On the other hand, looking at the corneal topography of the non-dominant eye, we can observe significant differences compared to the corneal topography of the dominant eye.

If you look at the difference map of the Scheimpflug corneal topography, although the central area has certainly changed, you can confirm that the mid-peripheral zone has changed to a greater extent.

In fact, the laser ablation is applied not to the central part, which is the corneal apex, but rather, more to the mid-peripheral zone. If the corneal apex is made to protrude forward, negative spherical aberration of the cornea occurs.
