Can Eye Bags from Fat Transfer Be Corrected Through Blepharoplasty?

Tuscany
Regarding the dark circles - filling the depressions under the eyes does not normally correct these circles unless they are created by shadows.
Regarding the bags - The most important information needed to correct your problem (under eye bags and lumps) is to determine exactly where the fat was injected. If the fat was injected into the sub-dermal or SOOF spaces a transconjunctival blepharoplasty would not be the best approach. If the fat was injected below the orbital septum, then a transconjunctival approach would work fine. If the injections were in both in front of and behind the orbital septum, I would prefer the sub-ciliary incision allowing easier access to all spaces.

Tuscany, Operations around the eye can be complicated, especially if you have already had other procedures affecting the tissues (fat grafting / injectables). You can likely be helped, but it is important that you go to someone with experience. It would help if you would post a picture so we could give you more specific advice.
