with your surgeon by now and hopefully you are no longer anxious about your healing. Photos look normal but be vigilant about implant position and if you find it wandering where you don't want it, you must let your surgeon know so maneuvers can be employed to maintain what you desire. Massage is used liberally in my practice and I find it help immensely with creating cleavage and 'natural' movements of the breast.
Breast implants should always be positioned centrally behind your nipples so that your implants give you the most natural shape. Your pictures show that your implants were placed correctly, and you look great!
For this early in recovery your breast augmentation result and implant position look normal. Over the next 3 months your breast implants should look much more normal and your inframammary crease be more well defined. You really cannot evaluate you results until at least 3 months.
your breasts look great to me for less than 1 week post-op. Your nipples should be in the middle.. Don't worry. They'll be fine
From the photographs it's impossible to tell about minor breast implant issues. However immediately after breast augmentation because of swelling the position can look abnormal.
Your breast implants appear to have been positioned correctly. Give them some time and they will soften up.
Implants look properly positioned as to how far apart they are. They are positioned right behind the nipples and areolas. Your breasts are more widely separated than in some women before surgery, and implants will not change that. As to the position in the vertical dimension, the steristrips are obscuring the area that a surgeon would need to see to make that assessment.
At any rate, your own surgeon is in a far better position to offer reassurance. All the best.
