Can I have eyelash extensions during a lower eyelid surgery?

No, you may not have eyelash extensions prior to surgery due to the risk of infections. Those extensions are full of bacteria. Please follow your surgeon's instructions.

Many thanks for participating in the RealSelf community and for your question. The most authoritative answer will be forthcoming from your Blepharoplasty surgeon's office. Transconjunctival procedures and open procedures differ. How important to you is your blepharoplasty result vs. maintaining your lashes? Long lashes may interfere with surgeon's view of your detailed anatomy. Extensions may be damaged during the procedure, or may contaminate the surgical field because they're impossible to completely sterilize. If lashes are important, maybe reschedule procedure. These are factors very specific to your situation and the type of blepharoplasty your surgeon is planning, so a phone call to the doctor is in order.

How are they doing the lower lid surgery? If it is "transconjunctival", on the inside of the lids, it may be less of an issue. If it is on the outside it is more in the way. I've done these both ways in people with lash extensions and it is doable, but... it makes it harder for the surgeon and there is a good chance some of the lash extensions fall off anyway.
