Revision double eyelid surgery experiences in Korea?

Korean surgeons do handle a high volume of revision eyelid cases, so experience is generally strong. Revision is genuinely more complex than primary surgery because of scar tissue, altered anatomy, and sometimes a shortage of skin, so it usually costs more (often 1.5–2x) and requires a surgeon who sub-specializes in revisions. Asymmetric crease height like yours is a common, fixable complaint, but the surgeon needs to assess in person — sometimes the higher side is lowered, sometimes the lower side is raised. Wait until tissues are fully settled (at least 6–12 months after the last surgery) before revising.

This is general information — an in-person consultation with a board-certified specialist is the only way to get advice tailored to your anatomy and goals.
