Hello, this is AB Plastic Surgery.

I wrote this post to answer some of the questions many of you have been curious about.

Q. Can eyelid correction alone fix uneven eyes?

A. Uneven eyes cannot be corrected with eyelid correction alone.

There are various causes of uneven eyes. If the unevenness is caused by different double-eyelid heights on both sides or by different degrees of sagging skin, it can improve simply by resetting the double-eyelid line height or removing the stretched skin.

However, if the strength of eyelid opening differs between the two eyes, unevenness can be improved through eyelid correction.

Eyelid correction surgery for uneven eyes is complicated because of Hering's law.

Since this is a medical term, it may feel difficult, but to explain it simply:

Originally, because one eye had ptosis, the brain recognizes and tries to open the eyes wider.

But if eyelid correction surgery is performed on the eye with ptosis, the brain thinks it does not need to open that eye as widely.

However, the brain sends the same signal to both eyes. Then, because it also thinks the other eye without ptosis does not need to open as widely,

its eyelid-opening strength becomes weaker. In conclusion, the other eye, which had less ptosis, ends up becoming the eye with more severe ptosis.

Of course, depending on the dominant eye (the eye mainly used between the two), Hering's law may not apply.

But basically, when performing eyelid correction surgery for uneven eyes, both eyes must be operated on and finely adjusted based on this theory.
