Strattice for bottoming out and contracture
Strattice is a material used for an internal bra, and is very helpful in supporting implants that have dropped or move too far to the side. It is also very effective at preventing capsular contracture, so it may actually be the answer for both of your problems. With contracture, usually the scar capsule is removed, so there is less coverage of the implant. Using Strattice adds the coverage and support back in addition to helping prevent recurrent capsular contracture.
Solely based upon the photo, it looks like the breast on the your left( right side of photo) has bottomed out compared to the one on the opposite side. You probably will need a pocket adjustment to fix this.
Update to my question: What procedure works for bottoming out and capsular contracture?
Although accurate advice would necessitate in person examination your picture and description are helpful. Based on this information, you are likely dealing with a breast implant encapsulation on your right side; treatment may involve capsulectomy and/or the use of acellular dermal matrix. On your left side, it is likely that you are dealing with breast implant displacement/malposition; treatment would involve internal suture repair ( capsulorraphy) of the inferior and lateral breast implant pockets. You may find the attached link, dedicated to revisionary breast surgery examples, helpful to you. Best wishes.
Left breast implant dropping
This is discussion even at our plastic surgery meetings. First in my opinion, your left (photo) breast implant sits closer to where it was meant to be. The photo right is too low and has bottomed out. The star gazing nipple tendency is an indicator of the center of this implant below the nipple complex.
An inferior capsulorhaphy can fix this and if needed change to a textured implant and this will likely not occur again.
