What Can I Do About Loss of Outer Eye Lashes with Upper and Lower Bleph?

It is unusual for eyelashes to fall out after surgery, and usually this is temporary. If at a year out they have not grown back, it is unlikely that they will. Hair transplant has been done for this.

Loss of eyelashes following a blepharoplasty is rare.  I would think that it should only be temporary.  Latisse only prolongs the active phase of hair growth and will not stimulate the follicles to make an eyelash.  Hopefully over time your eyelashes will improve.  

Eyelash loss after upper and lower eyelid surgery, while rare, is usually temporary and the result of stress to the eyelash follicles. However, this loss, called telogen effluvium, usually improves after 3-6 months. With canthopexy, there may have been some damage to the lash follicles at the outside corner. Latisse can sometimes help awaken a stunned follicle, but if there is significant injury, the follicle may no longer be able to produce a hair. Eyelash extensions may help provide a cosmetically acceptable result. Another option would be to undergo eyelash hair transplantation. An experienced hair transplant surgeon would be best suited to speak with you regarding your options.
