Do I have to have implants to get Galaflex?

I have a few questions about Galaflex mesh. Do you have to have implants to get Galaflex? Since it causes hardening of the tissues will this make it harder to have future procedures, will future procedures take longer to heal? Does Galaflex cause the breast to become firm and hard? Can you feel the scar tissue like you can feel incision scars? Can someone show me pictures of what Galaflex looks like years after the procedure? What is the normal rate for this procedure?
