After eyelid surgery 6 weeks ago, I'm left with a white line along my upper eyelash line both sides. Will this go away?

White line after eyelid surgeryphotos would be most usefulIncisions fade after 4-12 months.  there is always a small scarI will usually use sutures which
will dissolve on their own, without need for removal. Initial mild discomfort
is controlled with oral medication.

Patients who wear contact lenses can usually
wear them again after 10–14 days.

Swelling, discoloration, and some bruising are
to be expected. It is not unusual to have some difficulty seeing during the
first day or two after surgery because of the swelling and eye
lubricants/ointment used during and after surgery.

The description does not help other than to tell us that you are having an issue that is bothering you after surgery.  Consider reposting with representative photographs.  Thanks.

Since you are only 6 weeks out it is tough to tell exactly what you are talking about but wound healing can take over a year so I would see your doc or be patient.
