Short answer
Epicanthoplasty (앞트임) opens the inner corner, lateral canthoplasty (뒤트임) moves the outer corner, and lower canthoplasty (밑트임) lowers the outer part of the lower lid.1, 5, 6
The Korean outer-corner version usually makes the eye longer and slightly less slanted, the opposite of a fox eye, which lifts.1, 12
Before you pay, get in writing which corner, which direction, how many millimeters and the revision plan; this guide prints no Seoul prices.

Take one question into the consult: "Which corner is the problem on my face, and which way will it move?" If the answer is "all three, a bit," ask again.

What is the difference between epicanthoplasty, lateral canthoplasty and canthopexy?

They work on different corners and move them in different directions. Epicanthoplasty changes the skin fold over the inner corner. Lateral canthoplasty cuts and re-anchors the outer corner. Canthopexy only tightens the outer corner with sutures, without cutting the tendon.1, 12, 13

Name on a Seoul menu Corner What it moves Usual goal
앞트임 (epicanthoplasty) Inner The skin web over the pink inner corner Eye looks longer toward the nose
뒤트임 (lateral canthoplasty) Outer The outer corner, released and re-fixed further out Longer eye, softer slant1, 2
밑트임 (lower canthoplasty) Outer lower lid The lower lid edge, set lower Taller opening5
Canthopexy Outer Existing tendon, tightened with stitches Support, small lift, often with lower lid surgery12, 13
"Fox eye" Brow, temple, sometimes outer corner Brow tail and skin pulled up and out Lifted, almond look

Q. Why does the same word mean opposite things? In the US, canthoplasty is often called "cat eye surgery" because it lifts the outer corner.12 In Korea, cosmetic lateral canthoplasty is usually done to lengthen the eye and lower its slant, because an upward slant can make the eye look smaller and sharper.1 Same surgery name. Opposite brief.

Which corner is actually making my eye look small?

Often only one, and the fix depends on which. Look straight into a mirror in daylight, no makeup, and check each corner separately. Then let a surgeon measure; this is a conversation starter, not a diagnosis.

  • Inner corner: Is a skin fold covering the pink tissue next to your nose? That fold is the epicanthal fold, and it is what 앞트임 changes.6 No visible fold, little to gain.
  • Outer corner: How much room sits between the outer corner and the bone beside it? Surgeons measure this distance and the slant before cosmetic lateral canthoplasty, because that space limits how far the corner can move.1
  • Lower lid: Does the lower lid sit high on the colored part of the eye? That is the zone 밑트임 targets.5
  • Upper lid: Does the lid cover part of the pupil? That is a crease or muscle question, not a corner question. Our double eyelid guide covers ptosis and creases, and the upper eyelid guide covers heavy skin and a low brow.

Q. Can a corner fix a droopy lid? No. If the lid sits low over the pupil, a longer eye can still look tired. Sort the lid first.

The outer corner is where 뒤트임 and canthopexy work. Ask how much room your face has there.

Is a fox eye lift the same as eye-corner surgery?

Usually not. "Fox eye" is a look, not one operation. It can be a thread lift that pulls the brow tail and temple up, a toxin brow lift, an outer-corner lift such as canthopexy, or a mix.12, 16

Quick decoder:

  • Fox eye vs cat eye: In US usage, "cat eye surgery" usually means a canthoplasty that lengthens and lifts the outer corner.12 "Fox eye" more often means lifting the brow tail and temple, so the eye looks pulled up from outside.
  • Fox eye vs brow lift: A brow lift moves the eyebrow. It does not change where the eyelids meet. If the corner itself is your problem, a brow lift is the wrong tool.
  • Fox eye with Botox: Toxin can relax muscles that pull the brow down, so the brow lifts a little. The effect lasts about three to six months.16 Our Botox guide explains what Seoul menus mean by the word.
  • Fox eye thread lift: Threads under the temple skin. Extrusion, infection, swelling, pain and an unfavorable result are listed risks.17 Our thread lift guide covers threads in depth.

Q. If I want a fox eye, should I book 뒤트임? Not by default. The common Korean 뒤트임 brief lowers the slant.1 If you want a lift, say "lift" and point at the brow, the corner or both.

What can go wrong at the inner corner?

The two big worries are a visible scar and an inner corner opened too far. Surgeons agree there is no single standard technique, and fine, tension-free closure matters for the scar.6, 7

What the papers report:

  • Thick scars: A 2025 review of 85 papers names hypertrophic scarring as a common surgeon concern, partly because many candidates scar more easily. Newer methods release tension and report low recurrence and high satisfaction, but there are no randomized head-to-head trials.7
  • Too much pink: Excess exposure of the inner pink tissue (the caruncle and tear lake) is a named problem of epicanthoplasty.8, 9 It can make the look harsh.
  • Asymmetry: One corner opens more than the other.
  • Revision exists, but it is its own surgery. One series treated 324 people unhappy with a previous epicanthoplasty, for asymmetry, too much pink and scars. Minor complications occurred in 4.6%.9 A smaller 2026 series of 32 revisions reported 2 reoperations.10

Q. Can an inner-corner opening be undone? Partly. "Restoration" operations can pull skin back over the corner, but they leave their own scar and are judged case by case.9, 10 Treat 앞트임 as hard to reverse.

Q. Can Botox help the scar? In one randomized split-face trial, 5 units of toxin injected 6 to 7 days after epicanthoplasty improved scar scores on the treated side in the 30 people who finished.11 It is a doctor's call, not a routine add-on.

What can go wrong at the outer corner?

The most common letdowns are the corner sliding back and the corner changing shape. Korean surgeons list deformity of the outer corner (webbing or rounding), recurrence, visible pink lining and a lid that turns out as common complications.1

  • It slides back: Recurrence can shrink the white triangle at the outer corner, so the eye looks unchanged or even smaller.1
  • Rounded or webbed corner: Cutting the corner can blunt its sharp angle. Some techniques try to preserve it.1
  • Pink lining showing, lid turning out: Often linked to where the corner is fixed to the bone. Fixed too far out can cause it; fixed too low can look unnatural.1
  • Watering from the scar: A case series described tear-gland fistulas after cosmetic lateral canthoplasty, done by four different surgeons. Treatment was excision and repair.4
  • Lashes rubbing, swelling of the eye surface, surface erosion: listed complications of canthoplasty in general. Exposure can also leave the eye dry.1, 14

For context, in a US series of 600 people (mostly functional cases, average age 55), 18 had another operation within two years for a recurring lid or corner problem.19 Korean cosmetic series of 200 to 246 people report satisfied patients and no severe complications, but they are single-center reports without control groups.2, 3

Q. What is the one number to ask for? Millimeters. Ask how far the outer corner should move on your face and what happens if it settles back.

How long is canthoplasty recovery, and when can I fly?

Plan on about a week to look presentable and about a month for most swelling. Bruising typically settles in 7 to 10 days, stitches usually come out at 5 to 7 days, and the incision can stay red for up to three months.14

A practical timeline:

  • Days 1 to 3: swelling and bruising peak. Cold compresses, head up, prescribed drops.14, 15
  • Days 5 to 7: stitch removal and a check.14 Keep this visit in Seoul.
  • First 3 weeks: no rubbing, no swimming pool or sauna, no contact lenses.14, 15
  • Up to 3 months: scars fade from pink. Judge the shape after that, not on the flight.

ASPS suggests waiting seven to ten days after eyelid surgery before flying20, and our stay planner builds a trip around that window. Swelling tips are in our swelling guide.

Q. Is a canthopexy faster? Usually. ASPS surgeons describe canthopexy as less invasive, with a shorter recovery and lower risk than canthoplasty.12

How much does eye-corner surgery cost in Korea?

This guide prints no Seoul prices, because quotes for the same name can cover different work. What moves the number is which corners, whether it is combined with eyelid surgery, revision versus first time, and the anesthesia.

Get an itemized won quote that lists:

  • Each corner as its own line: inner, outer, lower.
  • Combined procedures as separate lines, for example a double eyelid.
  • Anesthesia type.
  • Stitch removal and the check visit.
  • Prescriptions and drops.
  • Revision policy and fees if a corner settles back.
  • VAT included or added.

The old tourist VAT refund on cosmetic surgery has ended; our cost guide explains quotes, fees and that change, and the foreigner price guide explains posted non-covered fees.

Q. What about fox eye lift cost? It depends on what "fox eye" means on that menu: threads, toxin or surgery. Ask which one before comparing numbers.

Can I combine eye-corner surgery with double eyelid surgery?

Yes, and it is common. In one Korean series of 712 epicanthoplasty patients, 707 had a double eyelid procedure at the same time.8

Keep three things straight:

  1. The quote: each procedure is its own line. Inner-corner work is not included unless written. Our double eyelid guide explains the crease side.
  2. The recovery: combined surgery means one swelling period, but the longest part sets your flight date.
  3. The refusal: if you do not want a corner changed, write that before surgery day.

Who is a poor candidate for eye-corner surgery?

People whose problem is somewhere else, and people with little room to move. A precise look at your lid anatomy comes before any plan.1

  • No real inner fold: 앞트임 has little to remove.
  • Little space between the outer corner and the bone: 뒤트임 has little room.1
  • A lid that covers the pupil: start with the lid. (double eyelid guide)
  • Dry eye or a history of lid problems: tell the surgeon first. Exposure and dryness are known complications.1, 14
  • Thick scars or keloids elsewhere: ask about scar plans.7
  • A previous corner surgery: revision is harder. Bring the old operation notes.9, 10
  • Not able to stay about a week: the stitch visit belongs in Seoul.

Patients with darker skin types can ask about scar and pigment risks in our guide for Black, Latina and other non-Asian patients.

What should I ask at the consult?

Send photos first, then ask the same questions in the room. Written answers are your record.

Send the clinic:

  • Front photos in daylight, eyes open, no makeup, plus one looking up and one with eyes closed.
  • One line on the goal: "longer toward the nose" or "outer corner lower", not "bigger eyes".
  • Your dates in Seoul and flight date.
  • Past eye surgery, dry eye, contact lens use, scarring history.

Ask the surgeon:

  • Which corner, which direction, and about how many millimeters?
  • Canthoplasty or canthopexy, and why?
  • How much pink at the inner corner will show?
  • What happens if the outer corner slides back?
  • Who operates, and are they a plastic surgery specialist?
  • When are stitches out, and when can I fly?
  • What is the revision policy, in writing?

Our consultation checklist has the full list for any procedure.

This article is for general education and is not medical advice, a diagnosis, or a promise of outcome. No prices for Korea are printed here; a clinic's itemized quote is the only number that counts. Techniques, recovery times and complication figures come from published case series and society or hospital pages, which vary by surgeon and patient. Dry eye, lid laxity, a previous eye operation, a tendency to thick scars and any vision problem need a qualified surgeon's review before eye-corner surgery.
