How can one fade scars?

I was in a severe accident a few years ago and after a few rounds of surgery, I still have some massive scars (1/2 inch wide in places).

My surgeons have stripped the scars several times, but each time they come back as bad as the last time.

Are there any other methods to fade surgical scars other than further surgery?

And to clarify, 3 separate surgeons have tried stripping them, all highly recommended plastic surgeons and no success from any of them.
