Lower eyelid retraction. 4 months ago I had deep plane facelift and upper/lower lid bleph. Do I need another surgery?

You are referring to postblepharoplasty lower eyelid retraction. Revision eyelid surgery is possible to lift the lower eyelid. It is important to understand canthoplasty alone will NOT be enough and in fact can distort your eyes. The lower eyelid needs to be lifted called lower eyelid retraction surgery. It also appears you have large eyes which predisposed you.

You have some scleral show on both sides, more on the right.  You also appear to have large eyes.  It would be helpful to see where the lids were pre-op.Fixing this is not an easy revision.  It can sometimes require a graft in the lid, and can change the shape of the eye.  This is especially true in someone who has prominent globes.  I would wait at this point to at least 6 months post-op.  Some massage upward on the lid may help.    

When your lids don't close completely you always worry about dry eyes and corneal ulceration.Perhaps massage and taping especially at nite to make sure your ids are closed.If this does not improve you may want to get some tightening to your lower lids.
