The engine probably looks the same inside.
And that's likely the bigger issue. All things considered the filter held up reasonably well.
That said, the Prizm (Corolla) is a very reliable tough little car/engine. If it's running ok, a few shorter OCI's (3-4k), with a quality cleaning oil like PYB or (5k)PP, should help clean it up. Others can speak to MMO, but another option, 3/4-1qt. added the last 1k of oci wouldn't hurt either imo. Might not hurt to change the pcv too.
