What canthopexy does
The outer corner of the eye is supported by the lateral canthal tendon — a band of fibrous tissue anchoring the lid edge to the bone. With age (and especially after surgery that disturbs the lid support structures), this tendon can stretch, causing:
- Lower lid descent — "scleral show" (white visible below the iris)
- Lid laxity — the snap-back test becomes slow
- Rounding of the eye shape — loss of the natural almond contour
Canthopexy tightens the lateral canthal tendon by anchoring it firmly to the orbital bone, preventing or correcting these issues.
Canthoplasty goes further — the tendon is fully detached and re-attached at a higher position. More effective but more involved.
When canthopexy is essential
Canthopexy is essential — not optional — in:
- Subciliary lower bleph in patients with negative vector anatomy
- Lower bleph in patients with positive snap-back test (lid laxity)
- Revision lower bleph after previous over-resection
- Any case where significant orbicularis muscle is being released
In these scenarios, skipping canthopexy substantially increases the risk of lower lid retraction — the most-feared cosmetic complication of lower bleph.
When it's optional
- Transconjunctival lower bleph in young patients with elastic lids — canthopexy may not be needed
- Standard subciliary bleph in middle-aged patients with no lid laxity — canthopexy is a small added safety margin but not strictly necessary
Frequently asked questions
Does canthopexy change my eye shape?
Done properly, no — it preserves your natural canthal angle while adding support. Aggressive canthoplasty can subtly raise the outer corner (a deliberate aesthetic in some cases — 'almond eye' or 'fox eye' technique); standard canthopexy for support purposes is invisible.
Does canthopexy add recovery time?
Minimally — the same surgical access used for the bleph is used for the canthopexy. Some additional swelling at the outer corner for ~1 week, otherwise identical recovery.
Not sure if you're a candidate?
Blepharoplasty is most successful when patient anatomy, age, and goals align with what surgery can realistically deliver. Send three facial photos (front, profile, eyes-closed) and Doç. Dr. Erdal will give you an honest, no-pressure suitability assessment before you commit to anything.
