Muscle separation again and how do you fix it? (Photos)

I am 56 and had a tummy tuck/breast augmentation in 2006. R implant leaking, so I had a consult w/another Dr (original Dr moved out of state). I also showed the Dr my abdomen - I have 2 unequal vertical lumps on each side under my belly button, which you really notice when I tense the muscles. Abdominals are very weak. I had an MRI which said that everything looks fine, but it's obviously not. What is going on? How do you fix it? The plastic surgeon says he has not seen anything like it.
