Curious about cause of lower eyelid retraction (Photo)

I underwent lower blepharoplasty over 6 months ago, resulting in mild retraction to my left lower lid. The lower lid is now thick, with either persistent swelling or possibly a slight Entropion. I frequently struggle with dry eye now, both are very gritty, red and uncomfortable a large proportion of the time. I’m curious as to whether this requires scar release, or whether something else is going on. I’m also wondering what the risks of repair being unsuccessful or resulting in further issues.
