Follow up question to one about eyelid notch; does the notch generally get healed on its own? (photo)

After 3  months healing than consider revision surgery. unless you feel there will be not enough correction than precede NOW! 

Sometimes these notches will heal in, or at least heal in enough that they are not very visible.  This can take a few months.  If it does not heal you will have to remove the notch and reclose the lid.  This may be tough as it appears that the lid is pretty tight and is already pulling at the lateral canthus.  From this picture you look fairly young so not sure why the initial surgery was done, and why they thought your skin was too damaged to do the incision in the lateral canthus.
