Lower lid rounding after lower eyelid surgery usually does not get better with time. Now that you're about 6 weeks out, it's unlikely that it will worsen much more, if that's any comfort. There are several causes of lower eyelid rounding, but causes include overly aggressive resection of skin or muscle, poorly executed subciliary incisions, tethering of a transconjunctival incision, or a failure or recognize or appreciate pre-existing lower eyelid laxity (too loose a lower lid). There are some procedures that can correct lower lid rounding if it's severe, but maturation of the scars and resolution of any swelling are usual prerequisites before attempting these reconstructions. Good luck, --DCP
