What is canthoplasty?
Lateral canthoplasty reshapes the outer corner of the eye by releasing and re-attaching the lateral canthal tendon to change the corner's position, angle or horizontal length. Unlike canthopexy, which only supports the corner, canthoplasty creates a true shape change, so it is used selectively and always with adequate lower-lid support to avoid rounding or scleral show. It is often combined with lower-lid or under-eye surgery.
Why choose Sinsa L for canthoplasty
- Selective use — canthoplasty is chosen only when anatomy calls for real shape change; otherwise canthopexy is preferred.
- Support built in — lower-lid tone is measured and supported to prevent rounding.
- Whole-eye design — corner, lids and crease are planned together.
- International-friendly — English support, remote photo consults, transparent quotes and travel-aware scheduling near Sinsa Station.
Who is a good candidate?
- Short or downward-slanting outer corners you would like reshaped
- Corner rounding after previous surgery
- Planned lower-lid surgery where corner reshaping helps the result
- Good lower-lid tone, or willingness to add a support procedure
- Realistic, natural-shape goals
Techniques we offer
Lateral canthoplasty
Releases and re-anchors the tendon to adjust angle or length.
Canthoplasty + lid support
Combined with canthopexy or a lateral tarsal strip to protect lid position. Canthopexy →
With under-eye surgery
Paired with fat repositioning for a smooth lower lid and balanced corner. Fat repositioning →
Revision of the corner
Correcting over-widened or rounded corners. Revision →
Canthoplasty with under-eye surgery
In this case canthoplasty was combined with under-eye fat repositioning and micro-fat grafting, refining the outer corner while smoothing the under-eye.
Corner changes are kept subtle to avoid an operated look.

Frequently asked questions
Will canthoplasty make my eyes look bigger?
It can lengthen the eye slightly or change the corner angle, but the aim is a natural proportion, not a dramatic change.
What is the difference from canthopexy?
Canthopexy supports the corner without cutting the tendon; canthoplasty releases and re-anchors it to change the shape.
Can it cause scleral show?
It can if the lower lid is not supported, which is why lid tone is measured and support added when needed.
Is there a visible scar?
A small scar at the outer corner usually fades and becomes hard to see.
Can it be combined with under-eye surgery?
Yes — it is often combined with fat repositioning or lower blepharoplasty.
