Hi good evening! i have had a lower left eyelid since i was born if i recall well. is it necessary to go and attend a surgery?

Maybe: I also have the same thing. Unless your vision is impaired by this I would leave it alone. See an opthalmolgist for an opinion.

Ptosis: It depends on the reason for the asymmetry of your eyelids. If you have an anatomical/cosmetic defect that is bothering you, then yes have the surgery performed. If the condition does not bother you then maybe you don`t need the procedure. Ask your doctor about the risks and benefits of foregoing surgery :)
