My double-eyelid line was thick and round, so my eyes looked overall round and a bit asymmetrical. I had surgery with eye correction and two-line double eyelid surgery, because I wanted that roundness gone, and finally it seems to have improved a bit(?)..
My eyelid skin is quite thick, so the swelling that others say goes down in a month seemed to last even longer for me...So I practiced opening my eyes more often too...The feeling of looking like big round eyes seems to have improved a lot, and as for symmetry, they did match it as much as possible, but from what I heard, they checked the eyelid line height several times during surgery! So is it 100% symmetrical now??....nope, not yet. I still have parts that bother me if I look closely.. But it's only noticeable to me, so I guess it's not bad at that level(?) Still, it was a meaningful time in my own way...If you have questions, leave a comment!
