Had undereye filler dissolved and left with hollow eyes and volume loss (Photo)

I had undereye filler three years ago and about two years into having the filler my eyes would start swelling in the undereye area and they looked discolored. I went to the dermatologist and they told me it could be allergies, but even with allergy medication the swelling would not go away. A year ago, I decided to have my undereye filler removed and now I feel my face looks completely different. What can I do to fix the hollowness? I’m terrified of getting filler again.
