Is it possible to move my nipples more central? (Photo)

Thank you for the pictures. It's possible. I definitely would wait six months. You need to evaluate your breast at that point to see what the upside and downside of performing the procedure

There is a relatively wide range of normal in how closely positioned the nipples are in patients who have never had surgery. In that case the nipples can be moved more centrally at the expense of incisions (scars) either completely around the areola or the medial half. Only modest changes in nipple position are possible.  The position of the implants make a big difference.  In your case, your implants may not be centered behind your nipples and breast mounds. If they are placed medially in an attempt to give cleavage, then they will displace the nipples laterally. Preoperative pictures would be necessary to evaluate that.  Larger implants or adjustment of the position of their placement could be done with revisional surgery, but at the price of much more "side boob" which you may not want.  I would discuss your options with your surgeon and give things time to settle down.

Nipples tend to point in a direction perpendicular to the chest wall. So yours are in a normal position for the procedure you had based on your anatomy and chest wall. Now it is possible to move them more medial once the swelling has gone down. But I would not recommend this as the risk of more prominent scaring and distortion or the nipple itself would be high. You would most likely regret doing anything after you see the results and wish you had done nothing but by that time the damage would have been done. So my advice is to leave them where they are. 

You seem to be very early in your recovery.  Wait for everything to settle down.  To move nipples towards the middle can be done by repositioning your implants to create the impression of moving to the middle, or actually moving the nipples but that means putting scars around your areolas.

Obviously, you have recently had a breast augmentation, judging by your pictures.  The addition of breast implants should simply add volume to your breasts, not change the shape of them.  You did not include a pre-op picture so it is difficult to see if this is the case for you.  Ideally, the implants should be centered behind the nipple/areola.  Sometimes, in an attempt to create better cleavage, doctors will undermine the skin too far over the chest bone.  This causes too much fullness towards the middle of the breast and not enough out to the side.  In other words, the implants are NOT centered behind the nipple/areola.  In fact, this may cause the nipple/areola to rotate outwards and point laterally like yours do.  In this case, the solution is to go back to surgery and re-build the cleavage back where it was originally. 

An honest assessment to your posted issue is NOT without increased visible scarring. I would leave alone in this case... 

It is too early to see the final results of your augmentation. The cause of nipple lateral position is either anatomical position of nipples before augmentation or due to implant placement. Your before picture can be helpful.  The repositioning of the nipple-areolar complex does not work well when moving sideways. Please give it six months and then discuss your concerns with your surgeon. 

It is possible to have a small amount of central movement with a modified peri-areolar lift, moving the areola toward the center rather than upward. More movement is possible with a modified "lollipop" lift, again moving to the center, but this would leave a scar that most would find unacceptable. Disucss with ;your surgeon. 

There are two ways to move the nipples.  The most reliable is with a periareolar scar (half moon).  The other is more involved using an internal method to shift the NA complex but is more reliable if the implants are submammary than submuscular.  This involves more surgery however including removing the implants temporarily in surgery.
