Double Eyelid with or without Ptosis surgery? (Photos)

Hi,Thank you for your detailed question. Based on what you’ve described, your ptosis doesn’t seem to be severe, so it's not absolutely necessary to combine ptosis correction with upper blepharoplasty unless you are aiming for both functional and aesthetic improvement at once.
That said, you can always choose to have ptosis correction later, after your blepharoplasty, if you feel it's needed. It’s also important to understand that achieving perfect symmetry is not possible — since we all naturally have some asymmetry, and surgery can improve but not completely eliminate that.
If your main concern is achieving a more defined crease and youthful upper lid contour without compromising a natural look, upper blepharoplasty alone might be a good starting point. However, this should be carefully evaluated in person, ideally with photos and a physical exam, especially considering your brow dynamics and forehead compensation.
Best wishes,Dr. Furkan
