Considering Lower Eyelid Surgery - suggestions to support mid face and cheek area? (Photo)

A photo with your face in repose would have been more helpful for evaluating your issue. However, a robust HA volumizing filler works very well for addressiving cheek volume loss and restoring a more feminine, heart-shaped oval face. It usually secondarily improves the under-eyes, as well.
Should the under-eyes require additional improvement, this can be achieved with the use of a low viscosity, cohesive, malleable HA filler. And finally, if the muscle under the eyes is felt to be contributing to the problem, a couple of tiny microdroplets of Botox can help to slim down the protruding belly of this muscle.
You would be wise to consult with an experienced, board certified dermatologist injection expert and best of luck.

You may benefit from a lower blepharoplasty, fat grafting, soof midface lift, or something else. A smiling photo is a hard one for assessment.

Based on this photo you seem to have a condition called malar hyperplasia, small cheek bones what is the reason that this condition is present since your childhood. Augmentation of cheek bones with implants or fat grafting in combination with lower blepharoplasty would be my choice. Hope this helps. Good luck.
