Areola and Nipple Repositioning After Breast Augmentation

Breast and nipple asymmetry is the rule of nature; Very few women have perfectly symmetrical nipples and breasts. When the nipples are pushed farther from the chest by an implant, the asymmetry is really magnified.
In your case, at this time, I would recommend you do nothing. Your breasts are still swollen and the implants are still high (especially the left implant). I would wait at least 6-8 months until everything is soft and the implants are in their normal position. At that time you would need to re-evaluate your appearance and just how important better (not complete) symmetry is important to you.
If you decide to proceed, you would require a areolar narrowing (to achieve perfect circles) and a periareolar Mastopexy scar around the new areola. To read more about it, please see the link below.

Generally any procedure designed to reduce the size of your areola to the left, right or down will leave a scr which may be incomspicuous or visible depending on your skin type. The scar from raising the areola is the least visible. An abnormally high nipple is difficult if not impossible in some cases to pull down.

Mastopexy is the procedure that lifts and repositions the breast and the areola which can leave very nice or poor scars depending  on your skin type. I have developed a technique which I call the "Internal Lift" or an internal mastopexy which can be performed during during or after an augmentation procedure. This is very effective in mild cases of brest/nipple and areola sagging which leave no additional scars, as I perform it thourgh the original breast augmentation incision.
