Fat injections under the eyes - risks?

Diana.   Fillers or fat is a nice option for the sunken areas below the eyes called tear troughs.  Minor issues of fat transfer include over correction, Asymmetry or small lumps caused by fat lobules.  A rare but serious complication is blindness caused by inadvertent injection into a blood vessel creating blockage of the retinal artery causing blindness.  For that reason I only inject the face with small, blunt cannulas, which decreases the chances of entering a blood vessel.

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  Fat grafting under the eyes can be very effective if good technique is used.  The most common risk is asymmetry or small lumps, but this can usually be avoided with small micro injections of fat.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.
