Asymmetrical sunken/hollow eyes after blepharoplasty 6 years ago; fat transfer to fix it? Are there any risks? (Photo)

 Hi and thanks for your question. Fat transfer is a routine procedure for how long this around the eyes. Make sure that you see a very experienced board-certified plastic surgeon regarding this or any other cosmetic plastic surgery procedure. The final outcome is most dependent upon doing your research and  seeking a surgeon who is certified by the American Board of Plastic Surgery. That is my best advice after 30 years performing cosmetic plastic surgery. Best of luck. 

The risk that your surgeon told you about is the possibility of introducing fat intra-arterially that would travel to your retinal artery, clog it off and cause blindness. There is this possibility, but it is EXTREMELY rare and these days surgeons who do a lot of this will use blunt micro-cannulas that are less likely to pierce vessels and even if they do, the fat embolus introduced is microscopic. Also, I would ask if your surgeon has a protocol for what to do in the event of an emergency.
