As you can see from the below answers, all the physicians are in agreement that the problem can be treated nonsurgically with a filler, either fat or dermal injectable, such as a hyaluronic acid or calcium filler.
Injectable fillers need to be placed deep along the bone and placed slowly and carefully. These will last about one year.
Surgical treatment requires repositioning the fat in the lower eyelid over the rim and into the tear trough defect. I have performed this both through an external incision below the lashes as well as on the inside of the eyelid. In your case, I would do this through the inner eyelid because you don't have excess skin to remove. This will give a longer lasting result
