Would a Canthoplasty or an Upper Blepharoplasty Surgery Benefit my Eyes? (photo)

What a canthoplasty achieves is proper positioning of the outside corner of your eyes, otherwise known as the lateral canthas. A lateral endoscopic brow lift is another potential consideration to help support the soft tissue and the lateral aspect of your eyes. A conservative upper blepharoplasty will also effectively eliminate the "weighed down" look you're noticing around your eyes.

You should consult with a board certified facial plastic surgeon for a full assessment of your options. To get a sense of  the permanent improvement a brow lift can give, you may want to try an injectable Botox treatment as a temporary solution to relieve the heaviness you feel around your eyes.

Certainly combining any or all of these procedures, as appropriate, is commonly done. This also makes the most sense, since you will receive the results you are looking for with a much shorter recovery time.

Looking at those photos I think an upper lid bleph would be fine.I really do not think you really need a lower lid bleph/canthoplasty.

Conservative upper blepharoplasty can help achieve your goal but NOT canthoplasty.  Again, do NOT do canthoplasty.  See an oculoplastic surgeon.
