The REAL cure:

The typical characteristic of Chromatic Abberation is a radial magnification error of the green image content relative to the other colors, beginning from the center with a factor of 0.99 to 1.01.

The Radial Shift option of the free Photoshop plugin "Panorama Tools" can reverse and extinguish the error. I know of no better solution.

Once you have experimentally identified the correct value for your lens and focal length, the correction value can be stored and reloaded.

For the same lens and focal length the CA correction can be executed as a batch job. CA correction MUST be the first step of image processing. The procedure can be found here:
