The difference at a glance
Despite both being eyelid procedures, canthoplasty and blepharoplasty target different structures: canthoplasty repositions or tightens the outer corner of the eye (the lateral canthus), while blepharoplasty removes or redistributes excess skin and tissue from the upper or lower eyelids.
The confusion is understandable — both can be performed around the same area and are sometimes combined — but their visual goals are distinct.

Canthoplasty vs Blepharoplasty at a glance
| Look for | Canthoplasty | Blepharoplasty |
|---|---|---|
| How it looks | Outer eye corner appears lifted, elongated, or more angular; almond or fox-eye shape | Eyelids appear smoother and less heavy; upper lids show more crease; lower lids lose puffiness |
| What to check | Position and angle of the outer eye corner; lateral canthal tendon area | Skin drape along the upper lid; presence or absence of under-eye bags |
| In photos | Outer corner sits higher or the eye reads as more elongated horizontally | Upper lid looks less hooded; lower lid contour appears cleaner and less puffy |
| Impression | Eye shape change — the corner angle and eye opening geometry shift | Eye area rejuvenation — the lids look less tired or heavy without necessarily changing corner angle |
Side-by-side look
How to tell them apart
Spotting Canthoplasty
- Outer eye corner appears lifted or angled upward
- Eye opening reads as more elongated or almond-shaped
- The lateral canthal angle (outer corner) looks tighter or more defined
- Sometimes described as a fox-eye or almond-eye result
Spotting Blepharoplasty
- Upper eyelid skin sits higher, revealing more of the lid crease
- Lower lids show reduced puffiness or under-eye bags
- Overall eye area looks less heavy or droopy
- Eye shape geometry stays similar; the lid surface changes
10-second visual check
If the outer corner of the eye appears repositioned — sitting higher or pulling the eye into a more angular, elongated shape — the look aligns with canthoplasty. If the eyelid skin looks smoother, less hooded on top, or less baggy underneath without a clear shift in corner angle, the look aligns with blepharoplasty.
Can You Have Both?
Canthoplasty and blepharoplasty are frequently performed together, since one addresses corner position and the other addresses lid tissue.
A combined result can show both a lifted outer corner and a cleaner lid surface, making the two effects harder to separate in a single photograph.
Canthopexy — a less invasive version of canthoplasty using a suture rather than full dissection — is also sometimes paired with blepharoplasty, adding another layer of overlap in how results appear.
Frequently Asked Questions
What is the main visual difference between canthoplasty and blepharoplasty?
Canthoplasty changes the angle and position of the outer eye corner, while blepharoplasty changes the amount of skin and tissue on the eyelids themselves. One shifts eye shape geometry; the other refines lid surface and contour.
Can canthoplasty and blepharoplasty be performed at the same time?
Yes — they are commonly combined because they address different structures in the same area. In photographs, a combined result shows both a repositioned outer corner and smoother lid contour.
How does canthopexy differ from canthoplasty?
Canthopexy uses a suture to support the lateral canthal tendon without full dissection, making it a less structurally involved approach than canthoplasty. Both aim to influence outer corner position, but the degree of change they produce differs.
