How Will Eyelid Surgery Affect Eyelash Regrowth?

The eyelashes should not be impacted by blepharoplasty, unless they are inadvertently transected, in which case they should regrow.

Thank you for the very good question. Patients are often concerned about their cut lashes or burned lashes following eyelid surgery. The good news is that the lashes grow back normal within 2 months and usually even sooner. 

If you lost lashes after a lower blepharoplasty, it is because the surgeon operated too close the follicles of the eyelashes.  Unfortunately the damaged lashes may never grow back.  They can also return after being dormant for several months.  WHen they do regrow, scar tissue adjacent to the hair follicle can cause the lash to be misdirected.  Latisse will not benefit this situation.  First Latisse should not be used on the lower eyelid.  Second, if the lash follicle is damaged, stimulating it with Latisse still will not make an eyelash grow.  Eyelash transplants are a very bad idea because the graft hair growth too long too rapidly and can end up irritating the eye.

In general having cosmetic eyelid surgery should have no effect on your eyelash growth.  Bleapharoplasty should not disturb the lid margin or lashes.

When performed by a skilled and
experienced plastic surgeon, eyelid surgery, or blepharoplasty, should not
affect eyelash growth. If, for some reason, the eyelash hair follicles are
damaged during the procedure and scar tissue arises, it can impede eyelash
growth. Generally with careful surgery the risk of damaging the eyelashes should ever very small. If you have had eyelid surgery and
are losing your lashes, follow up with your surgeon.
