Sunken eyes - what can be done to open them up as much as possible? (Photo)

Thank you for reading. My eyes have become sunken over the last few years, hopefully it's obvious by the photos that they don't protrude as much. They've also gotten noticeably darker (and my vision has gotten worse). What can be done to open them back up as much as possible to how they were before? I've looked at canthoplasty/canthopexy and upper/lower blepharoplasty, but have no idea which one (or all) would be most appropriate. Any guidance welcome.
