In short. Epicanthoplasty releases the vertical skin fold at the inner corner of the eye, the epicanthal fold. The fold is a normal variant, common in East Asian eyelids, and surgery is only considered when it is prominent enough to shorten the eye, distort the inner crease, or pull the lid strongly inward. Many people keep it.

Key points

  • The epicanthal fold is normal and common, especially in East Asian eyelids.
  • Surgery is considered for a short-looking eye, a distorted crease, or a strong inward pull.
  • The inner corner has no crease to hide a scar, so a fine line may stay visible.
  • Swelling settles in one to two weeks; the scar refines over months.
  • It is often combined with double eyelid surgery, but that combination is optional.

What is an epicanthal fold?

The epicanthal fold is a vertical skin fold at the inner corner of the eye. It is normal and common, especially in East Asian eyelids, and many people choose to keep it. Reducing the fold can make the eye look longer and allow a double eyelid crease to flow more naturally towards the inner corner.

When is surgery considered?

Surgery is a personal aesthetic decision, usually considered when the fold is prominent enough to make the eye appear short, to distort the inner part of a crease, or to create a strong inward pull on the eyelid. It is not required at the same time as double eyelid surgery. Combining the two is common but optional.

Keeping the fold Releasing the fold
Appearance The eye may look shorter, and a crease may stop at the fold The eye can look longer, and a crease can flow towards the inner corner
Who it suits Many people, because the fold is normal and common A prominent fold that shortens the eye, distorts the crease, or pulls inward
What surgery does No surgery Small incisions; skin rearranged and redistributed
Scar None A fine line at the inner corner, more visible than a crease-line scar
Recovery None Swelling settles in one to two weeks; the scar refines over months
Main risks None from surgery Visible scarring, asymmetry, an over-open corner, partial return
With double eyelid surgery An independent choice Often combined, but the combination is optional

What does the procedure change?

Through small incisions at the inner corner, the surgeon rearranges and redistributes skin so the fold is softened and the inner corner appears more open. The goal is a natural, unstretched look, not a permanently wide-eyed appearance.

Why is the scar at the inner corner more visible?

Upper eyelid incisions hide in a crease. The inner corner has no natural fold to conceal a scar, so the fine incision line there is more likely to be visible, especially in the first months, and it can occasionally remain faintly perceptible long term. People who form prominent scars should weigh this carefully. Because the scar site is more exposed than in standard double eyelid surgery, the decision deserves particular care and a clear understanding of healing.

How long does recovery take?

Swelling at the inner corner settles over one to two weeks, while the scar refines over months. Combining the procedure with double eyelid surgery can produce a more balanced overall change, and the recovery for the two is shared.

What risks should be weighed?

Risks include visible scarring, asymmetry, an inner corner that looks too open, and a rare tendency for the fold to partly return. A partial return is uncommon but recognised. The aim is a softened, natural corner rather than a permanently wide-eyed appearance.

Frequently asked questions

Do I have to have epicanthoplasty at the same time as double eyelid surgery?

No. The fold is normal and common, and many people choose to keep it. It is considered when the fold is prominent enough to make the eye look short, to distort the inner part of a crease, or to pull strongly inward on the eyelid. Combining the two is common but optional.

Will the scar at the inner corner be visible?

The inner corner has no natural fold to conceal an incision, so the fine line there is more likely to be visible than a crease-line scar, especially in the first months, and it can occasionally remain faintly perceptible long term. People who form prominent scars should weigh this carefully.

Can the fold return after surgery?

A partial return of the fold is an uncommon but recognised possibility. Other risks include visible scarring, asymmetry and an inner corner that looks too open. The aim is a softened, natural corner rather than a permanently wide-eyed appearance, and swelling at the inner corner settles over one to two weeks.

Risks & Limitations

  • Dry eye, watering or a gritty sensation, which may be temporary or lasting.
  • Difficulty closing the eye fully (lagophthalmos); if it persists it can expose the cornea and needs review.
  • Asymmetry, an uneven crease, or under- and over-correction, which may require revision.
  • Bruising and swelling that can take several weeks to settle.
  • Visible or thickened scarring; scars are permanent but mature and fade over 6–12 months.
  • Altered or reduced sensation around the lid, usually temporary but occasionally lasting.

When to Seek Care

  • Any sudden change in vision, loss of vision, or double vision — seek emergency care immediately.
  • Severe pain, or an eye that becomes tense, hard and swollen.
  • Inability to close the eye, or new redness and pain in the eye itself.
  • Spreading redness, warmth, pus or fever above 38 °C.
  • Bleeding from the wound that does not stop with gentle pressure.
