Squeezing an encapsulated breast implant in the hopes of resolving a capsular contracture is of historic value only. This practice fell out of favor over 15 years ago. The idea of applying force to tear open the capsule caused bleeding, implant rupture and on occasion would force silicone into the breast tissue further complicating the problem and eventual required surgical correction.
It is a bit concerning that you even know what this is. Do not allow anyone to perform this on you. Seek out a board certified plastic surgeon to help you with this problem.
