Can a canthopexy produce a lateral canthal tilt? (Photo)

Canthopexy by itself will not achieve natural long-lasting results you want. The lower eyelids also need to be raised. 

Dr. Robert Flowers, now retired from practice in Honolulu, was famous for his cat eye results.  He accomplished this with a repositioning of the lateral canthal tendon, elevating its position to a higher point on the lateral orbital rim.  I suggest discussing this with a board certified plastic surgeon familiar with this technique.  

Aloha and thanks for your question. Yes a canthopexy can produce a lateral canthal tilt. But without photos, or better, a personal exam and discussion, it's difficult to make specific recommendations.        I would recommend you see an experienced Surgeon certified by The American Board Of Plastic Surgery[ABPS] and a member of The American Society of Plastic Surgeons (ASPS) for an in-depth consultation to review your options. Mahalo, Dr D
