Can someone help me fix my left broken cheekbone once and for all? (photos)

I have three fractures on my left cheek area, temple, corner or the eye, and middle of the cheek, I had an implant put in, over twenty years ago it's allot flatter now and seems to have slipped down a bit, as I have well under that eye. The eye is also starting to sag on that side wondering if anyone can design an implant especially for my situation?
