Will Massaging Implants Two Years Post-op Help to Lower the Higher, Harder One?

Unfortunately, I don't believe that massage will be of any benefit. It is best that you consult with the operating surgeon. If you indeed have a capsule contracture, you may benefit from removal of the scar tissue and replacement of the implant. Even with this, you may be at a higher risk for a recurrence of the problem.

Two years out means that your hard implant (capsular contracture) will probably not respond

at this point. It can't hurt but probably will not help much. Are you a smoker? - I ask that question as the risk of harness is up to 30X greater and stopping nicotine would help as would certain medications such as Singulair. However it would be an off FDA usage and you would have to have a thorough discussing and informed consent to use it. 

I suspect that you will need surgery to correct this decision. Make sure you see a surgeon board certified by the American Board of Plastic Surgery with experience in secondary breast problems.
