Can filler be used to correct double eyelid left over from ptosis surgery?

While it is possible to find injectors to provide this service, it is not actually a service that will help you. You state that you had ptosis surgery and revisional ptosis surgery in the past. Your photos demonstrate that you have persisted ptosis in both upper eyelids. Your left upper eyelid is somewhat more ptotic than the right side. Interestingly you have a stronger compensatory eyebrow elevation on the right side compared to the left but both are relatively elevated. If I were able to physically examine you, I would look to determine how much upper eyelid excursion you are capable of making. This is called levator function. Think of this as the motor function of muscle responsible for opening the upper eyelid. When the function is less than 8 mm it is challenging to improve these eyelids surgically. When the levator function is greater than 12 mm, it is more likely that revising the upper eyelid ptosis surgery is worthwhile. This is something that is easily measures at the time of an in person consultation. If your levator function is good, I would recommend revision the ptosis surgery of both of these upper eyelids. It is often possible to improve the elevation of the upper eyelids, lower the upper eyelid crease, and often allow the eyebrow to relax to a more normal position after surgery. It is also possible to reconstruct the upper eyelid fold. I am attaching a paper comparing the repair of failed ptosis surgery with post-upper blepharoplasty eyelids. I think you will find this interesting. Also I am attaching a video that shows how this surgery is performed. Unfortunately the fillers treatments to not address the upper eyelid ptosis or the compensatory eyebrow elevation. They simply make the upper eyelid bulky and this is not likely to be helpful for you.

I would be very reluctant to inject fillers in this area.
It’s not a typical area to treat so I don’t think you’re gonna find many providers who have experience.
If you find someone who does and they can show you lots of before and after pictures Then you may want to consider trying it.
I don’t think it’s going to give you the results you’re looking for and there is some risk involved with injections in this area.
