It can often take several months after breast augmentation before you reach your final result. Swelling is common and will frequently be asymmetrical.
Also, when implants are placed in a submuscular pocket, they may temporarily appear high and unnatural until the pectoralis muscle stretches to accommodate the new implant. This process may take months, and can also be asymmetrical, especially if the muscle on the dominant side of the body is thicker.
In terms of the amount of fluid in the implants, it is highly unlikely that a 10ml (10cc) difference between implants would give a visible difference in breast size. Bear in mind that 10cc is equivalent to 2 teaspoons, so chances are it would hardly be noticeable since that breast was smaller to start with.
Most likely the visible difference at this early stage of healing is due to swelling and/or muscle tightness. This sort of temporary distortion should resolve over time.
I also instruct my patients in massage of the implants to promote stretching of the inner and lower pectoralis muscle, allowing the implant to drop into position sooner.
As for the wrinkly feeling you are noticing at the right breast, that may be due to some rippling of the saline implant shell. Since that implant was filled with less saline, it may exhibit more rippling than the left side.
The pectoralis muscle coverage at the lower lateral part of the implant is thinner, so it is more likely that you will notice rippling in that area.
The rippling itself is nothing to worry about unless it ultimately becomes highly visible. Usually the rippling is not seen unless you are very thin and have very little overlying tissue.
