Do eye exercises help ptosis even by just a little?

In my experience, exercises do not help to improve ptosis.  I have not seen ptosis improve from patients doing exercises.  The best and most predictable treatment is surgical repair.  It is important to choose a surgeon who is specifically trained in ptosis surgery and also has a lot of experience doing the surgery.  Good Luck.

Eyelid ptosis happens because the muscle that lifts the upper eyelid gets stretched/loose from constant work!  The muscle lifts the eyelid 20,000 per day! So further exercising not only doesn't help, it can make it worse. The only effective treatment is eyelid ptosis surgery, which can be done under local anesthesia.

As stated by others, most commonly ptosis of the upper eyelid is caused by a disinsertion of the tendon that is used to lift the eyelid.  Surgery repairs this disinsertion.  "Exercising" the eyelid or manipulating stresses the tissue insertion of the levator and foreseeably will make the problem worse.  Ptosis is corrected with surgery.

Unfortunately ptosis of the eyelid does not respond to exercises.  It is an anatomical problem that needs surgical correction.  This is best evaluated and done by an Oculoplastic surgeon.  Good luck!

You did not include a photo, but Ptosis, if present, is caused by an eyelid muscle weakness that cannot be corrected by exercises. I am sorry your previous procedures did not meet your expectations.  The only proper treatment is a surgical correction in the hands of an experienced surgeon who regularly performs Ptosis repair.  Ptosis surgery is very, very challenging and few surgeons are specialists in this delicate and precise surgery.  Best wishes in your search!
