Rhonda -  I can't tell you what the right thing to do here is but I think I can help you in your thinking about it to help get you to a good solution.  Hope that makes sense.

The first thing is to figure out (with your doctors?) what is causing the pad.  Is the pad a small lump of fat?  Is it the lower edge of the orbicularis oculi muscle that's sagging?  Is it excess skin?  It's likely to be one of these 3 or a combination of them.  What is your prior doctor's opinion on this?  First, you need a diagnosis of the problem. 

If their explanations aren't satisfactory, the next thing to do is schedule with 2 other plastic surgeons for a short (hopefully no charge) consultation and hear their opinions.  If they disagree, then even possibly get a third opinion until you feel confident that someone has nailed the diagnosis and then given you some reasonable options.  Without seeing you it's impossible to know if the Juvederm just wasn't a good idea or it was a placement problem.  

 The worst thing to do in this situation is to rush into another surgery.   Hope this helps.  Dr. I
