In order for implants to feel soft and natural, it is ideal for the implant pocket to be substantially larger than the implant, with movement of the implant within the pocket. Capsule contracture occurs when the implant is squeezed by a shrinking pocket, making implants feel firm and sometimes even rock hard. In your case the pocket is obviously larger than the implant, but the nature of the saline implants, which can readily fold and ripple, makes this folding both palpable and visible. This is more prominent in some patient than in others, particularly where there is thin covering of breast tissue over the implants. The real solution to this problem is the use of gel implants, which feel more natural and are much less likely to fold and ripple. I have seen a large number of patients with similar problems who have elected to exchange the saline implants for gels with very positive results.
