Canthoplasty vs Canthopexy: What’s the Difference?

Canthoplasty and canthopexy are both eye corner procedures that focus on the outer corner of the eye (lateral canthus), but they are not the same surgery. The difference lies in how invasive the procedure is, how much structural change is made, and what problem it is meant to solve.

Understanding this distinction is essential, because choosing the wrong procedure can lead to overcorrection, unnatural eye shape, or unnecessary revision.

What Is Canthoplasty?

Canthoplasty is a reconstructive eye corner surgery.

It involves:

  • Cutting and releasing the lateral canthal tendon
  • Repositioning or reshaping the outer eye corner
  • Re-fixating the tendon to a new position

Because the structure is fully adjusted, canthoplasty can change the shape, angle, and length of the eye.

What Canthoplasty Is Used For

  • Drooping outer eye corners
  • Downturned or sad-looking eyes
  • Horizontal eye enlargement
  • Significant eye shape correction
  • Revision of previously overdone eye surgery

This is the procedure commonly referred to in Korea as lateral canthoplasty.

What Is Canthopexy?

Canthopexy is a supportive tightening procedure, not a shape-changing surgery.

It involves:

  • Tightening and reinforcing the existing canthal tendon
  • Anchoring it without cutting or fully releasing it
  • Preserving the natural eye corner anatomy

Canthopexy focuses on stability and support, not visible enlargement.

What Canthopexy Is Used For

  • Mild eye corner laxity
  • Preventing drooping after lower eyelid surgery
  • Early aging changes
  • Supporting the lower eyelid
  • Reducing risk of ectropion (lid pulling down)

It is commonly performed as a preventive or adjunct procedure.

Key Differences at a Glance (Explained in Words)

Degree of Change

  • Canthoplasty: Structural change and eye shape modification
  • Canthopexy: Subtle tightening with minimal shape change

Invasiveness

  • Canthoplasty: More invasive, tendon is cut and repositioned
  • Canthopexy: Less invasive, tendon is tightened and reinforced

Visual Impact

  • Canthoplasty: Can noticeably lengthen or lift the eye
  • Canthopexy: Usually not visibly obvious

Risk Profile

  • Canthoplasty: Higher risk if overdone (round eyes, scarring)
  • Canthopexy: Lower risk, mainly supportive

Why Korea Is Especially Careful With Canthoplasty

In Korea, canthoplasty has a mixed reputation because:

  • Over-aggressive canthoplasty can cause unnatural eyes
  • Poor technique may lead to visible scarring
  • Excessive lengthening can distort facial harmony

As a result, many experienced Korean surgeons:

  • Recommend canthopexy instead of canthoplasty in mild cases
  • Use very conservative canthoplasty only when truly necessary
  • Combine canthopexy with other eye surgeries for support

This cautious approach is why Korean eye surgery often looks more natural.

Which One Do You Actually Need?

You may need canthoplasty if:

  • Your outer eye corner droops noticeably
  • You want true horizontal eye enlargement
  • You need correction after previous surgery
  • Structural repositioning is required

You may need canthopexy if:

  • You want mild tightening or support
  • You are undergoing lower eyelid surgery
  • You have early laxity, not shape issues
  • You want prevention rather than transformation

Many patients do not need either, despite requesting them.

Can They Be Combined?

Yes—but carefully.

  • Canthopexy is often combined with lower eyelid surgery
  • Canthoplasty may be combined with other eye shape procedures
  • Combination is only recommended when anatomy clearly supports it

Korean surgeons generally avoid stacking aggressive procedures unless absolutely necessary.

Recovery Differences

Canthoplasty

  • More swelling at the outer corner
  • Longer healing time
  • Final shape settles over months

Canthopexy

  • Minimal swelling
  • Faster recovery
  • Usually no obvious external change

Common Patient Misconceptions

❌ “Canthopexy will make my eyes bigger”
→ It won’t. It supports, not enlarges.

❌ “Canthoplasty is always better”
→ Not true. It carries more risk if unnecessary.

❌ “Everyone needs eye corner surgery”
→ Most people don’t.

Final Thoughts

The difference between canthoplasty and canthopexy is not subtle—it’s fundamental.

  • Canthoplasty = shape-changing, structural surgery
  • Canthopexy = supportive, stabilizing procedure

In Korea, the trend is strongly toward doing less, not more, and choosing the least invasive option that achieves a natural result.

A proper diagnosis of eye corner anatomy—not preference or trend—should determine which procedure, if any, is appropriate.

Swelling Stages After Eye Plastic Surgery Swelling after eye plastic surgery is normal, expected, and temporary. In Korea, surgeons place strong emphasis on educating patients about swelling stages because eyelid healing is gradual and early appearance does not reflect final results. Understanding each swelling phase helps prevent unnecessary anxiety and reduces the risk of premature revision concerns. Why Swelling Happens After Eye Surgery Eye surgery involves: Delicate skin Fine muscles (levator muscle) Fat compartments Dense blood supply Even small adjustments can cause visible swelling. Because eyelid skin is thin, swelling appears more dramatic than it actually is, especially in the first two weeks. Stage 1: Immediate Post-Surgery (Day 0–3) This is the peak swelling phase. What to expect: Significant puffiness Tight or heavy feeling Mild bruising (purple or reddish tones) Temporary asymmetry between eyes Difficulty judging crease height What this means: This is inflammatory swelling, not your final result One eye often swells more than the other Creases may look too high or uneven Korean surgeons consider this phase purely transitional. Stage 2: Early Recovery (Day 4–7) Swelling begins to gradually decrease, but is still noticeable. What to expect: Puffiness starts softening Bruising may change color (yellow/green) Eyelid movement feels stiff Crease still looks higher than final Important note: Many patients wrongly judge results at this stage Stitches are usually removed during this period (if incisional) Surgeons in Korea strongly advise not evaluating symmetry yet. Stage 3: Visible Improvement Phase (Week 2–3) This is when patients start to feel more confident. What to expect: Major swelling reduction Crease becomes more defined and natural Eyelids move more smoothly Asymmetry improves noticeably At this stage: You look socially presentable Photos start to look normal Residual swelling is still present internally Most Korean clinics consider this the “public recovery” phase. Stage 4: Settling Phase (1–3 Months) Swelling becomes subtle and localized. What to expect: Eyelid thickness continues to decrease Crease height lowers gradually Eye shape refines Skin softens This stage is critical because: Patients may think swelling is gone—but it’s not Final symmetry is still developing Overreaction here can lead to unnecessary revision requests Korean surgeons typically say: “Judge the result after 3 months, not before.” Stage 5: Final Healing Phase (3–6 Months) This is when results stabilize. What to expect: Swelling fully resolves Eyelid movement feels natural Crease looks softer and more blended Final symmetry is achieved For: Ptosis surgery → closer to 6 months Revision surgery → sometimes up to 12 months This is when surgeons can accurately assess if any adjustment is needed. Swelling Differences by Procedure Type Non-incisional double eyelid surgery Faster swelling reduction Most swelling gone by 2–3 weeks Incisional double eyelid surgery More swelling initially Takes longer to settle (up to 3 months) Ptosis surgery Swelling lasts longer due to muscle work Tightness may persist for weeks Lower eyelid surgery Swelling may descend into cheeks Can last longer but resolves naturally Common Swelling Myths ❌ “If it’s still swollen after 2 weeks, something is wrong” → False. This is normal. ❌ “Uneven swelling means surgical failure” → False. Healing is rarely symmetrical. ❌ “Crease height at 1 week is final” → Very false. Creases always drop as swelling resolves. How Korean Surgeons Help Minimize Swelling Typical post-op care includes: Cold compresses (early phase) Proper head elevation Anti-inflammatory guidance Avoiding alcohol and intense exercise Gentle scar and swelling care instructions Aggressive massage or early manipulation is usually discouraged. When to Contact the Clinic You should contact your clinic if you experience: Increasing pain (not decreasing) Sudden severe swelling on one side Signs of infection (fever, pus, worsening redness) Normal swelling does not worsen after the first few days. Final Thoughts Swelling after eye plastic surgery follows a predictable, staged process. In Korea, surgeons design procedures expecting this timeline and plan crease height and eyelid position accordingly. The most important rule: Never judge eye surgery results during swelling. Patience during healing is the key to appreciating a natural, balanced final outcome. When allowed to settle fully, Korean eye surgery results often look much softer and more natural than early post-op appearances suggest.
