Re-Produce Molded IEMs?

I have a pair of Ultimate Ears (before Logitech bought them) ~2009~ which I had custom molded to my ears. I still have them but the drivers are shot and the acrylic shockingly isn't clear anymore (I've cleaned them good).

Can I send these to another company to have new IEMs shaped or do I need to go back to an audiologist again?
