Lateral Canthoplasty in Seoul: Reshaping the Outer Eye Corner
The short answer
Lateral canthoplasty reshapes the outer corner of the eye by extending the opening outward and repositioning the canthal tendon, either to lengthen a short eye, soften a sharp upturned tilt, or support a drooping corner. In Gangnam it typically costs about KRW 1.5–3 million, takes 30–60 minutes under local anesthesia with sedation, and usually adds about 2–4 mm of length. Some relapse is common.
Key facts
- What it treats: Short outer corners, sharp upturned tilt, drooping corners
- Typical cost in Gangnam: About KRW 1.5–3 million
- Procedure time: About 30–60 minutes
- Anesthesia: Local with sedation
- Typical gain: About 2–4 mm per side
- Stitches out: About 5–7 days
- Key risk: Partial relapse as tissues tighten
How the outer corner is reshaped
The outer corner of the eye, the lateral canthus, is held in place by the lateral canthal tendon. This tendon anchors the upper and lower lids to the bony rim of the eye socket. Its length and the height of its attachment decide how long your eye looks and whether it tilts up or down at the outer end.
In lateral canthoplasty the surgeon makes a small incision at the outer corner and extends the opening outward. The lower part of the tendon is then repositioned and stitched to the rim, either slightly lower to soften a sharp, upturned eye or tighter and higher to support a drooping corner (canthopexy). The new corner is lined with the inner lid lining so it looks like a natural part of the eye. Because the outer corner has firm, elastic tissue, it often tightens back a little as it heals, so surgeons plan for this.
Most often chosen for and combined with
- Eyes that look short at the outer end
- A sharp, cat-like upward tilt you want softer
- A drooping outer corner or lax lower lid
It is commonly combined with epicanthoplasty to lengthen both ends, or with lower eyelid surgery when lid support is needed.
The procedure, step by step
Incision
A small horizontal cut is made at the outer corner, usually 3–5 mm long.
Release and reposition
The lower limb of the canthal tendon is partly released, the corner is extended, and the tendon is stitched to the periosteum of the bony rim at the planned height. The lining (conjunctiva) is sutured to the skin edge to form the new corner.
Where the incisions are made
At the outer corner, where the scar blends with the natural lid line.
How the scar heals over 12 months
The outer corner scar is usually subtle and fades within 3–6 months. Redness inside the new corner settles over a few weeks.
Recovery timeline
| When | What to expect |
|---|---|
| Days 1–3 | Swelling and tightness at the corner |
| Days 5–7 | Stitches removed |
| Weeks 2–6 | Shape stabilising, some tightening |
| Months 3–6 | Final length, accounting for relapse |
Is it right for you?
A good fit if you
- Have a clearly short or steeply tilted outer corner
- Have enough lid laxity for extension
- Accept that gains are modest
Another option may suit you better if
- Your eye looks short mainly because of an inner fold
- You want a strong "fox eye" lift: a temporal lift raises the outer brow area instead
Risks to discuss at your consultation
Ask about relapse, asymmetry, a rounded or webbed corner, lower lid pulling down, visible pink lining at the corner and dryness. Ask what percentage of relapse the surgeon typically sees.
Lateral canthoplasty cost in Seoul
Typical Gangnam quotes are KRW 1.5–3 million, often lower as part of a combined eye plan. See canthoplasty or epicanthoplasty to decide which corner to treat.
Lateral canthoplasty vs. epicanthoplasty
| Lateral canthoplasty | Epicanthoplasty | |
|---|---|---|
| Corner | Outer | Inner |
| Can change tilt | Yes | No |
| Relapse | More common | Less common |
| Scar visibility | Low | Moderate early on |
| Typical cost | KRW 1.5–3 million | KRW 1–2 million |

Patient questions
Frequently asked questions
How much longer will my eye look?
Typically about 2–4 mm, with some reduction as the corner heals and tightens.
Can lateral canthoplasty give a downturned "puppy eye"?
Combined with lower lid lowering techniques it can soften an upturned tilt, but changes are modest.
Why does the corner relapse?
The outer corner tissues are elastic and tend to pull back as they heal.
Is there a visible scar?
The scar sits at the corner and is usually subtle after a few months.
How long should I stay in Seoul?
About 7 days for stitch removal and a check-up.
