Buried-method double eyelid surgery is also known by several names, such as non-incisional double eyelid surgery and natural adhesion double eyelid surgery, and because the results are natural and recovery is fast, it is often used for a first eyelid surgery.

Buried-method double eyelid surgery is a surgical method that induces adhesion by using buried sutures through small openings between the eyelid skin and the tarsal plate.
While buried-method double eyelid surgery has the advantage of fast recovery, as time passes the tension of the sutures between the eyelid skin and the tarsal plate may decrease, or the tissue may loosen due to the so-called cheese wiring effect, which tends to loosen the skin adhesion of the double eyelid.
So after some time has passed since buried-method double eyelid surgery, some people undergo revision surgery because the line has become lower or the double eyelid no longer appears clearly defined.

And eye correction is needed to make the double eyelid line more distinct and help the eyes open better.

Ptosis refers to a condition in which the eyes have insufficient strength to open, and surgery to correct ptosis is called ptosis correction surgery.
In fact, because the term ptosis is a disease name, even when the strength to open the eyes is insufficient, it is very rare for someone to be so severely limited in opening their eyes that they would be given the medical diagnosis of ptosis.
For that reason, ptosis correction surgery for cosmetic purposes is called eye correction.

Correcting asymmetry with non-incisional eye correction.
Because the right eye (left side in the photo) has slightly weaker eye-opening strength, asymmetry can be corrected by performing a greater amount of non-incisional eye correction on that side and a smaller amount on the left eye (right side in the photo).
Of course, non-incisional eye correction has a limited ability to correct ptosis, so it is difficult to apply in cases of moderate to severe ptosis or severe asymmetry.
