The Korean terms 매몰법 대 절개법 (maemolbeop dae jeolgaebeop — burial/suture method vs incision method) describe the two surgical strategies at the center of this comparison. Both create an upper eyelid crease where none existed naturally, but they achieve this through fundamentally different mechanisms, suit different anatomies, and carry different long-term implications. Plastic surgery and dermatology collectively account for the largest share of procedures sought by international patients visiting Korea,¹ and double eyelid surgery is among the most frequently performed of all aesthetic procedures in the country.
Side-by-Side Comparison
The four main technique variants — non-incisional, partial incision, full incision, and full incision with ptosis (drooping lid) correction — differ across every clinically relevant dimension.
Non-incisional technique works by threading fine sutures (stitches) through small puncture points in the eyelid, creating an adhesion between the skin and the underlying levator muscle (the muscle that lifts the lid). No skin is removed. The crease forms immediately and the puncture marks are invisible within days. The limitation is structural: the adhesion depends on the sutures holding. In patients with thin eyelids and minimal fat, the tension on those sutures remains low and the crease is durable. In patients with heavier or thicker eyelid tissue, the sutures are working against greater mechanical load and loosening is more likely.
Full incisional technique removes a strip of skin along the crease line, allows direct access to remove or reposition orbital fat (the fat pad behind the eyelid skin), and creates a direct surgical adhesion between the cut skin edge and the levator muscle. The result is anatomically anchored rather than suture-dependent, which is why permanence is reliable. Ptosis correction — tightening of the levator muscle itself — can only be performed through an open incisional approach.
Partial incision is a hybrid: two or three small incisions (each 3–5mm) rather than a continuous cut across the full lid. It allows limited fat removal and a more stable adhesion than suture-only, with less trauma than full incision. It does not allow excess skin removal.
Cost Comparison
Prices below reflect the typical range across board-certified plastic surgeons in Korea as of mid-2026. Gangnam-gu, which receives approximately 60% of medical tourists seeking aesthetic procedures,¹ tends to sit at the upper end of each range. FX rate: USD/KRW 1,380; AUD/KRW 890 (July 2026).
The cost differential between non-incisional and full incisional at the mid-range is approximately ₩700K–1.5M (≈$505–$1,085; ≈AUD $785–$1,685). That gap disappears — and inverts — if the non-incisional result loosens and requires revision. A patient who pays ₩1.5M for suture technique and later pays ₩2.5M for incisional revision has spent ₩4M total, more than the upper-mid range for full incision performed initially.
Does Technique Choice Affect Surgeon Skill Requirement?
Both techniques require a board-certified plastic surgeon. In Korea, board certification from the Korean Society of Plastic and Reconstructive Surgeons (KSPRS; 대한성형외과학회, Daehan Seonghyeong Oegwa Haghoe — South Korea’s official professional and certification board for plastic and reconstructive surgeons)² requires completion of six years of medical school, a four-year plastic surgery residency, and passage of KSPRS board examinations.³ As of 2024, approximately 2,100 board-certified plastic surgeons are registered with KSPRS.⁴ Patients can verify certification directly through the KSPRS public registry by searching a surgeon’s name.⁵ Operating without this certification constitutes an illegal medical act under Korean law.⁶
The skill demand is not equal across techniques, however. Non-incisional surgery requires precise suture placement — the knot must be buried cleanly to avoid a visible bump under the skin, and the crease height must be set symmetrically without the visual feedback that an open incision provides. An imprecisely buried knot can create a palpable nodule. Asymmetry is more difficult to correct without converting to incisional.
Full incisional surgery, and particularly full incision with ptosis correction, requires a higher level of technical complexity. Ptosis correction involves identifying and tightening the levator aponeurosis (the tendon connecting the levator muscle to the lid), a structure that varies significantly between patients. Over- or under-correction of ptosis produces a lid that sits too high (causing a surprised appearance) or too low (incomplete correction). Revision of a poorly executed ptosis correction is among the most technically demanding procedures in oculoplastic surgery.
The practical implication: for non-incisional surgery, verify board certification and review before-and-after photographs for suture technique specifically. For full incision with ptosis correction, additionally ask how many ptosis correction cases the surgeon performs per year and whether they hold or have trained toward any of the KSPRS-recognized fellowship sub-specialties in relevant areas.⁷
Decision Framework: Choose Suture If / Choose Incisional If
One principle applies across all situations: the decision should be driven by anatomy first, recovery preference second. A patient with thick eyelids who chooses non-incisional to avoid a longer recovery will, in a significant proportion of cases, return for incisional revision — experiencing both recoveries and paying for both procedures. A patient with genuinely thin eyelids who chooses full incision to guarantee permanence accepts a longer recovery and fine-line scar that was not anatomically necessary.
The consultation is the moment to resolve this. A surgeon who proposes the same technique to every patient regardless of eyelid anatomy is not conducting an individualized assessment. A thorough consultation should include assessment of eyelid skin thickness, the presence or absence of excess skin, fat pad evaluation, and a lid-margin-to-reflex distance measurement to screen for ptosis.
