Mullerectomy for Proptosis Overcorrection - what can you on advise on the next steps? (Photo)

From the photos it appears you have significant left upper lid ptosis (droopy upper lid). If a muellerectomy did not work then an external levator resection is your next step to improve the eyelid symmetry.

Thank you for the photos, very helpful. Your photos show significant swelling which is common 10 days after mullerectomy. It is too soon to determine your final lid position at this time. If your surgeon was happy with your lid position on the day of your surgery then there is a very high likelihood that your eyelid position will improve as swelling resolves and fibrosis (scar tissue that is not visible under the eyelid) sets in. Patients with thyroid eye disease often have a lot of fibrosis that sets in about 6-8 weeks after surgery. This causes the surgery site to contract and the lid position to lift. If you give it more time and get past the swelling/inflammation phase your eyelid should lift into the desired position. It is common for swelling to make the eyelid look worse before it gets better. If you give it time and the lid position does not improve, then you have a couple options- ptosis surgery or ptosis eye drops (eye drops are not a permanent solution). An oculoplastic surgeon who is experienced with thyroid eye disease can discuss ptosis surgery options should that be necessary. Give it more time and speak to your surgeon for reassurance.
