Thank you for sharing your question. There are many good Oculoplastic Surgeons in Korea, but there are probably even more in the USA. See an experienced eyelid specialist who corrects complex cases for comprehensive evaluation and discussion of possible treatment. Good luck,
Asymmetry is normal, and may be improved on with surgery; however, if your goal is to create complete symmetry or you want to do surgery only because of the asymmetry then you may not be the right candidate for surgery. Please post your photos so that we can give you better recommendations.
It is not unusual for swelling or edema post-transconjunctival blepharoplasty to last for a couple months if not longer depending on the circumstances. You are still in the early phase of healing, just give it more time before any decision is made regarding future treatment.
