Failed Ptosis Surgery/any other options? (Photos)

It's difficult to know what options are available just from photos. It would be determined by the prior approach and the "function" of the elevator muscle of the eyelid. Getting a second opinion is reasonable at this point.

Sorry to hear about your ptosis problems.  All the Denver area ASOPRS oculoplastic surgeons are very well trained.  It appears you have poor levator function ptosis, and there are limits on how much lift you can get by tightening the tendon, muscle, and/or shortening the tarsus to maximize the lift.  It does not appear your ptosis is worsened.  If you are functional with your current eyelid heights and it appears your pupils are "cleared," in that the lid margins are at them or just above then you can put off a frontalis sling.  The sling procedure is very powerful, but the lid contours and getting perfect symmetry in terms of equal opening of the eyes is very difficult.  We usually will reserve this for the worst of cases for these reasons.  With that said, good cosmetic as well as functional results can be obtained with slings.  Best regards.
