Ptosis surgery in itself has its own unique challenges that involve the levator muscle. In a posterior approach or behind the eyelid, there are a couple of different procedures that are applied including Mueller’s resection or posterior levator resection as well as Fasanella-Servat. These are names that are technical but if somebody is first concerned about their eyelid height, it’s usually associated with some degree of swelling. The physical weight of the eyelid can also push the eyelid down. In addition, the healing processes of the muscle and all the other related issues that occur especially in the first one to two weeks after surgery also affect the eyelid height. From your photo, you don't have much swelling, so with that factor eliminated there may be an issue with the connection or the way the tissue is supposed to heal. It might also be because of some stitches that have been broken or because of some separation. I think that your surgeon must be at least informed. The timing of any revision surgery may be dependent on when your surgeon was informed. In my own practice, if such a thing would have happened, I would prefer to find out sooner rather than later. It’s a balance of when you want it operated depending on the degree of swelling, healing and what kind of impact there is on the eyelid height. When there is real separation before the tissue has the chance to develop scar tissue, there is actually a window of opportunity to do a revision without complications. It’s not necessarily within a few days or week. There is actually enough time, but it’s a matter of what your surgeon’s preference is. I should insist that you have your surgeon see you sooner. If there are any questions or concerns, I would always tell my patients that I’d rather see them than guess what they look like. Even if they show photos or pictures from their phone, or have someone to take a picture with a camera, it’s always better to see that patient. Considering that you had your surgery so recently, I think meeting with your doctor would be the best thing for you. Also, get an understanding of what’s going on and what would be the appropriate step to do next. I hope that was helpful, I wish you the best of luck, and thank you for your question.
