If all you need is canthopexy without eyelid skin rejuvenation/tightening and without fat removal/reposition, then, since it is a specialized procedure, that not all blepharoplasty surgeons feel comfortable doing, you will probably be charged around 75% of the surgeon's usual full blepharoplasty fee. However, if it is done at the same time as a cosmetic bleph, then you can probably expect to pay around 1.5X the amount that your surgeon charges for blepharoplasty.For various reasons, there's significant variation on what surgeon's charge, and you can find average charges for blepharoplasty (but not specifically for canthopexy) elsewhere on this site.
