Lower blepharoplasties with transposition of the fat to the hollow areas will likely provide the longest lasting correction.  Short of surgery, any of the fillers can be used.  However, the skin of the eyelid is very thin and may show lumpiness or irregularity.  Thus, make sure the injector is very experienced with using fillers in this area and that the filler is placed deep, near the bone, to try to avoid an unacceptable result, which may take months or longer to resolve.  Also, care should be taken to avoid an intravascular injection, which can lead to skin necrosis (loss) or blindness.  I prefer using Radiesse, which lasts clinically about one year, for augmenting this area. 

Soft Tissue Fillers

First, there are many names for similar procedures, which sound less invasive and better, but really aren't.   What you described is a type of tummy-tuck, but without tightening the muscle fascia (the layer covering the muscle).  Some people call this a mini-tummy-tuck with or without liposuction.  In any case, both procedures can be performed together assuming you are in good health and are a satisfactory candidate to have both procedures performed during the same operation.  The procedure should not last more than six hours, especially if it is going to be performed as an out-patient.  Typically, doing procedures together will save you some money.  Additionally, it would only require one anesthetic and one recovery course, rather than multiple.  You should consult with a board certified plastic surgeon about which option(s) are best for you.  Be aware of new-fangled names that may sound too good to be true.  Often, someone is just trying to get a marketing edge.

Laser resurfacing and chemical peels can make pores appear smaller with a lasting effect.  However, these procedures may be a lot to go through just to make pores smaller.  These procedures are really more designed to tighten facial skin, reduce wrinkle and pigmentation variation, and in addition they do make pores appear smaller.  I would suggest you speak with a board certified plastic surgeon to discuss your options.

Miscellaneous

Micro-liposuction with a small aspiration needle/cannula can be attempted to try to remove or break-up the fat deposit.  I've done this for a patient with a bulge on the upper lip and another patient with a bulge in the lower eyelid tear trough from fat injections many years prior and it yielded satisfactory results.  You can be left with a depression or contour irregularity if too much fat is removed.  I would recommend you see a Board Certified plastic surgeon to discuss your specific situation in more detail.

Fat Injection

I would not change your implants unless you wish to be larger or smaller, the implants are hard (capsular contracture), markedly rippled or ruptured.  If you have silicone gel implants, you may wish to get an MRI to see if the shell of the implants are ruptured.  If they are ruptured, the recommendation is to change them.  I would see a Board Certified plastic surgeon who can help you with this process.
