Hyaluronic Acid Filler Under Both Eyes

I had this done under both eye's 1 1/2 yrs ago and the H filler looks like bags under my eye's, it hasen't disolved as I was told it would after a year and I want it out. I have heard hyaluronidase can disolve the natural fat in your face if injected into the Hyaluronic acid, is this ture?? The doctor who injected the acid is going to inject hyaluronidase to disolve the H filler in a couple of months, the H filler would have been in for nearly 2 yrs by then, is this the best move to make?
