Can Upper Blepharoplasty Be Done Again?

Absolutely, the upper eyelids can be revised.  The results can be excellent.  The issues is what is going on with your eyelids and what needs to be done to fix what was done before and what needs to be done to achieve the vision you have for how your eyes should look.  I encourage you to study my website which has a wealth of information about revising eyelid surgery.  Ultimately what you need is a personal consultation to determine what is needed for you.  By the way, my Father use to say: "if the butcher tells you the meat is bad, you should listen." When a surgeon tells you that something can't be done, it often means that they lack the skills to do what you are asking.  You will need to search out a surgeon who devotes a good part of their practice to revising eyelid surgery.

A second Blepharoplasty can definitely be done
provided that your first surgery happened a decade ago. There is just one thing
to remember and that is you have to have enough extra skin in there because there
will be a removal of other scar tissues that will be done as well. It is a must
so that the result will be great.

Another Upper Blepharoplasty surgery could be performed if there is still extra skin that can be removed.  However, please keep in mind that upper blepharoplasty surgery is a delicate procedure and becomes even more challenging when scar tissue is involved.  Therefore it is important to find a doctor with the proper credentials to perform the revision.  I suggest finding a board certified facial plastic surgeon or general plastic surgeon with the training, skills and education to properly address your concerns.  I hope this helps!
