Why does one of my eyes open more than other after my nose was broken in assault? Can I fix it? (Photo)

Recently, over the last couple months, I have been realizing that one of my eyes opens more than another. I was restrained and thrown face first to concrete. Every piece of my nose was broken. I did have a reconstruction, but my nose is still crooked and not proportional in the tip or the bridge. I have been wondering if this could be causing my eye to open more, or if it is a result to trauma and an underlying issue. Where do I go to get this examine? Is it going to need surgery?
