You probably have right sided ptosis
It's difficult to answer your question precisely from the posted photographs, but most likely you have on the right side a weakness in the internal muscle that opens the eyelid. This is a common condition and the most common reason for an asymmetric result. I anticipate improvement over the ensuing several months as you heal from surgery. You may need a minor touchup at the six month mark if the asymmetry is significant.
Can a weak eyelid crease following surgery cause a droopy eyelid
Thank you for sharing your question. A weak eyelid crease does not cause a droopy eyelid; however, it can be a sign of a dropped eyelid. You probably had a lower eyelid on that side to start with. Many patients become more aware of a droopy eyelid when the skin is removed following surgery. This is one reason doctors take so many photos prior to surgery. I hope this helps.
