I understand about the wind shear but why was her eye ball replaced?

All big storms go through eyewall replacements. It can happen several times depending on how long the storm lives.

I'm tempted to make a witty comment, but hurricanes often replace their eyewalls as part of getting better organized.

It temporarily weakens them, but almost always leads to increased strengthening over the long term unless other factors intervene.
