Is it possible to lower overcorrected eyelid after ptosis surgery? (Photo)

In the photo, you are looking down. That prevents a ptosis surgeon from assessing the level of the two eyelids. A straight ahead photograph would provide much more information. The photograph you have provided looks like the upper eyelid are pretty even. That makes one wonder if you have a lid margin position issue or a fold symmetry issue. When ptosis surgery is performed, ptosis surgeons are not skilled in the aesthetics of this surgery. It is important to control the upper eyelid crease and anterior orbital fat to manage the volume of the upper eyelid fold. It can be frustrating working with ptosis surgeons because by an large they are not aesthetic surgeons. They are most concerned with getting the open so the eyelid does not block the vision. An accuracy of plus or minus 1 mm is very acceptable to them. However, that is a difference of 2 mm. In my practice, I recognize that standard is not nearly close enough. Generally the two eyelids need to be within 0.5 mm to aesthetically satisfactory. It is highly likely you will need to travel to get that level of care.

Yes that is possible but best to have more detailed evaluation to determine if that is the best option or something else.

Ptosis surgery is the most difficult type of eyelid surgery to achieve symmetry. The usual goal is to get the height of the upper eyelids within 1mm of each other. Overcorrection can be brought down with a second surgery, but there is always the risk of brining it down too much or leaving too high.

Its hard to tell how different they are from your photo as you are looking downward. The best away to assess eyelid height is with a photo from straight ahead with a camera flash.

You can always see another oculoplastic surgeon in your area for another opinion.
