Double eyelid surgery (쌍꺼풀 수술).

Double eyelid surgery creates a crease in the upper eyelid. The incisional method (절개법) opens the lid along the intended crease line, removes a small strip of tissue, and sutures the skin to the underlying levator muscle — making the crease permanent. The non-incisional or "buried suture" method (매몰법) passes fine sutures through tiny entry points, creating the crease without cutting — shorter downtime, but the crease can relax over 3–5 years. A partial-incision variant splits the difference.

People who want a defined upper-lid crease. Some pursue it for aesthetic balance; others for practical reasons — heavy upper lids pressing on the lash line. Korean surgeons typically run a pre-op assessment of levator function, lid thickness, and existing crease asymmetry before recommending a method. The buried method isn't available for every eye shape.

Which method the surgeon recommends and why. How many of that specific method they perform per week. The clinic's revision policy (buried-method creases can relax; incisional creases can drop). Whether the surgeon is board-certified in plastic surgery or oculoplastic specialty. Whether they use local anesthesia with sedation, or general. What is included in the quoted price.

Buried method: 3–7 days of visible swelling. Stitches are removed at day 4–5 (if non-absorbable). Most patients feel presentable in under a week. Incisional method: 7–14 days of swelling, stitches out at day 5–7, residual tightness for 4–8 weeks, full settling at 3–6 months.

Non-incisional (buried): ₩500,000–₩1,500,000. Partial incision: ₩1,200,000–₩2,500,000. Full incisional: ₩1,500,000–₩4,500,000. Gangnam flagship and Cheongdam clinics often run 20–40% above the upper end. Revision cases are quoted separately and typically run higher than primary surgery.

"Can I see un-retouched before/after photos of patients with my specific eye shape, taken at 3 and 6 months?" A confident surgeon will show them. A less confident one will show you marketing composites. That single question is one of the cleanest filters we know.

Most Korean clinics use local anesthesia with light sedation rather than general — you remain semi-aware, calm, and unable to feel pain, but you may sense pressure or tugging. The lid is numbed first with a topical drop, then with fine injections along the marking line, which sting for about ten seconds before going dull. During the buried suture method (매몰법), the sensation is mostly a series of small pulls as the threads pass through the lid; the procedure usually finishes in 20 to 40 minutes. Incisional surgery (절개법) takes longer — typically 45 to 90 minutes — and involves more sustained pressure, the smell of cautery, and at times the sound of saline irrigation. Patients rarely describe it as painful, but most describe it as strange. Immediately after, the lids feel heavy and warm, and vision is blurred from ointment rather than from the surgery itself.

Day 1 is the swollen day: lids tight, slightly bruised, occasional throbbing managed with paracetamol-based analgesics and cold compresses. Sleeping elevated is non-negotiable. By day 3, swelling begins to drop unevenly — one eye almost always deflates faster than the other, which can be alarming if no one warned you. By day 7, with stitches typically removed, the crease looks higher and harder than it will eventually settle. The final shape is usually visible around month three, and continues to soften through month six. Discomfort is rarely the issue patients remember; the wait for symmetry is.

Asian blepharoplasty has one of the longest published track records in aesthetic surgery, and the literature is consistent: serious complications are rare, but minor revisions are not. A 2022 review in the Indian Journal of Ophthalmology by Liu and Song (PMID: 35502011) categorises the recognised complications into five groups — patient dissatisfaction, crease problems, height problems, suture-related issues, and general eyelid surgery risks — and notes that asymmetry is the leading cause of dissatisfaction. A peer-reviewed analysis published in Facial Plastic Surgery (PMID: 33368082, 'Complications of Asian Double Eyelid Surgery: Prevention and Management') frames double eyelid surgery as a major contributor to blepharoplasty-related complaints across primary and revision cases, while a separate 7-year complaint analysis (PMC11898149) found a formal complaint rate of 0.98% across 2,545 revision double eyelid procedures.

On the buried suture method specifically, a Korean cohort study (PMID: 26413962) followed 204 patients (392 eyes) and reported a crease loss rate of 19.3% with the interrupted technique versus 8.6% with the continuous buried suture technique at minimum 3-month follow-up. Reported asymmetry rates in modern small-incision and partial-incision case series cluster between 1.2% and 4.6%, depending on technique and operator experience. Vision-threatening complications such as retrobulbar haematoma or permanent ptosis are rare in published Korean series, but they exist, which is why the literature consistently recommends operators with formal plastic surgery or oculoplastic training. None of these numbers replace a personal pre-op assessment, and revision rates published in journals reflect academic centres, not every clinic on a given street. Ask your surgeon for their own audited revision rate, in writing.

The crease changes how the upper lid folds when the eye opens, which changes the visible eye shape — but not the eye itself. A new crease exposes a strip of pretarsal skin (the lid platform) that was previously hidden, which is what makes the eye appear larger in photographs. The eye is the same size; the visible portion is what shifts. Lash position can also look slightly altered, because heavy monolid skin no longer presses on the lash line. Makeup application becomes the single most cited downstream change: eyeliner stays visible when the eye is open, eyeshadow has a defined zone to sit on, and false lashes attach more predictably.

Many patients are surprised by what the surgery does not do. It does not enlarge the eye — that is the role of medial epicanthoplasty (내안각) or lateral canthoplasty (외안각), which are separate procedures with their own scar profiles. It does not lift the eyebrow; chronic frontalis-muscle compensation from heavy lids can ease after surgery, which sometimes reduces forehead lines, but the brow position itself is unchanged. It does not change iris colour, eye spacing, or under-eye fat. And it does not produce a Western eye — the goal in Korean practice is a defined Asian crease, typically 6 to 8 millimetres from the lash line, tapered or parallel depending on the patient's underlying anatomy. Going in with photos of an outcome that contradicts your own bone structure tends to produce the dissatisfaction the literature describes. A measured, anatomy-led conversation with the surgeon is the better starting point.

Long-term outcome data for Asian blepharoplasty have improved considerably since 2015, with several prospective and large retrospective studies now available. A FACE-Q validation study published in the Journal of Plastic, Reconstructive & Aesthetic Surgery (PMID: 28579035) followed 200 young Asian patients (400 eyes) aged 21 to 30 after minor-incision double eyelid blepharoplasty and reported a mean satisfaction-with-eyes score of 81.7 out of 100, with 8 cases of partial fold loss and 4 cases of asymmetric fold across the cohort. The Korean buried-suture cohort study (PMID: 26413962) is the most-cited comparison of suture techniques: continuous buried suture preserved the crease in 91.4% of patients versus 80.7% for interrupted buried suture, with fewer suture-knot exposures in the continuous group. For scar visibility, published small-incision series report that mini-stab scars become clinically invisible by 3 months, while full-incision scars typically continue to mature through month 12 before reaching their final appearance.

Revision triggers reported across the literature are consistent: relaxation of the buried-suture crease (usually 3 to 5 years post-op), unintended height asymmetry, shallow or absent fold on one side, and triple-fold formation. The complications review (PMID: 33368082) notes that incisional revision is preferred over re-suturing when excess skin or fat is present, because incisional outcomes have a measurably lower relapse rate. On patient motivation and outcome perception, a multi-cohort study (PMID: 31853906) surveyed East and Southeast Asian respondents and explored motivations and post-operative perceptions, with patients who had undergone surgery reporting improvements in self-reported social and professional domains — though the study was self-reported and not blinded. A separate revision-focused review (PMID: 26306087) catalogues the technical causes behind each revision category — low fold, high fold, shallow depth, triple folds — and highlights that most revisions trace back to imprecise pre-op measurement rather than intra-op error. The takeaway across these studies is that satisfaction is high when expectations are anatomy-led and the surgeon is experienced; revision rates rise when neither condition is met.

The Korean post-op recovery market has shifted considerably in the last two years, and the procedure itself has not changed much — what surrounds it has. PDRN (polydeoxyribonucleotide), derived from salmon DNA and used in injectable and topical form for skin repair, has moved from clinic-only use into Olive Young's mass-market shelves, where related skincare searches grew nearly sevenfold in 2025. Patients now ask whether topical PDRN serums applied after the stitches come out can shorten the redness phase; published evidence is still early, and most Korean surgeons treat it as adjunctive rather than essential. Glass skin remains the dominant aesthetic endpoint that frames how patients judge the post-op face — the expectation is not just a defined crease, but a clear, light-reflecting lid surface, which means concealer-heavy routines are increasingly rejected in favour of barrier-repair Korean skincare routines centred on hydrating toners, ceramide creams, and broad-spectrum SPF.

Exosome facials, offered in many Gangnam clinics from 2025 onwards, are marketed as a recovery accelerator after eyelid surgery; clinical data in this specific indication remain limited, and patients should ask whether a given clinic uses regulated, traceable exosome products or unverified imports. None of these trends replace the basics — sun avoidance, no rubbing, no makeup until cleared, sleeping elevated. They sit on top of conventional recovery, not in place of it. Treat them as optional add-ons to discuss with your surgeon, not as a substitute for the proven post-op protocol.

Will I be awake during surgery? In most Korean clinics, yes — local anesthesia with light sedation is standard. You will be aware but calm, and the lid itself is numb.

Can I wear contact lenses during recovery? Most surgeons ask you to switch to glasses for 2 to 4 weeks; lens insertion involves lid manipulation that can disturb sutures and swelling.

Will it look natural? Natural is anatomy-dependent. A crease set 6 to 7 millimetres from the lash line on an eye that supports it usually reads as natural; an over-high crease rarely does. Ask to see un-retouched 6-month results on patients with similar eye shape to yours.

Can I see my eye shape preview before deciding? Most clinics use a fine blunt probe to simulate the proposed crease in front of a mirror, which is the closest preview available. Digital morph apps are marketing aids, not predictions.

How visible is the scar long-term? Buried-method entry points are usually invisible by 3 months. Full-incision scars take 6 to 12 months to mature and remain faintly visible to a close observer in some patients.

Can the buried method be redone if it relaxes? Yes, and revision is common; many surgeons convert relaxed buried-method creases to a partial or full incisional revision rather than re-suturing.

Is it safe if I wear glasses constantly? Glasses do not disturb a healed crease. Heavy frames pressing on swollen lids in the first 2 weeks are the only short-term concern.

Will I need to take time off work? Buried method: 5 to 7 days for visible swelling. Incisional: 10 to 14 days. Plan video-call avoidance accordingly.

Can it be combined with epicanthoplasty? Yes, it is one of the most common combinations in Korea. The trade-off is a slightly longer recovery and an additional small scar at the inner corner. Discuss with your surgeon whether your anatomy benefits from the combination, or whether the crease alone is enough.
