Recent Muellerectomy, My Eye Looks Smaller, Is This Due To Swelling?

Until the suture is removed at about a week, swelling in the eyelid frequently is retained and this weighs the upper eyelid down.  Once the suture is removed, the swelling tends to disappear and this helps with the upper eyelid position.  If you responded well to the neosynepherine test in the clinic prior to surgery, I would be patient.  It may take several weeks for the swelling to resolve and allow you to realize the benefit of this surgery.  Your eyes look small now because of this normal swelling

The swelling that you have experienced following your mullerectomy is normal.  I advise my patients that after surgery they will most likely experience some noticeable swelling that will subside within two to six weeks. . Patients should know some minor swelling can remain for as long as six months, and their lid contours may continue to change.  Final results may not be seen until the six month mark. There are several exercises that you can do to assist with healing as well.  I suggest discussing your concerns with your surgeon.  Best of luck, Dr. Clevens

It is not unusual for the operated eye to look smaller after a Muellerectomy.  You need to wait until the swelling resolves before you can judge the result of your operation.
