Distort > Optics Compensation is intended for removing and reintroducing
distortion.  It's fairly straightforward and requires you to adjust the
properties manually as it does no analysis of the footage.  This is usually
easiest to do on footage that should have strong vertical or horizontal
lines in it.  You can put a layer with the grid effect above your footage
to guide the process.

Once you have the properties all set for your undistortion, you'll need
another copy of the effect applied after compositing (on an adjustment
layer, or up a comp level) with the "Reverse Lens Distortion" checkbox
enabled in order to redistort the footage.

Other than that I know that The Foundry's CameraTracker has some lens
distortion features that will analyze a sequence and generate data on
distortion that can be used to undistort/redistort.  There's at least one
free tutorial on using that feature:
