Have been boxing and stopped, but one eye is larger than the other? (Photo)

So I've been boxing for a year.About half a year ago I was hit in the left eye and supposedly my left eye socket was "fractured" now it has healed itself back up. I noticed one eye is smaller (the left) than the right eye. Could it have healed wrong? This was never an issue before the accident . Ive heard about plastic surgery but that is the chance of the surgery messing up? Or creating more problems than solving ? Thank you.
