Double eyelids but want larger and brighter eyes, should I get double eyelid surgery or just ptosis correction? (photos)

I agree with the other physicians here that you do not have ptosis. If you want a more wide-eyed look, it is achievable with blepharoplasty. Please find a facial plastic surgeon with expertise in treating Asian eyes. I hope this helps.

I don't think you need ptosis surgery but rather double eyelid (Asian blepharoplasty) only. But best to see an oculoplastic specialist for evaluation, either in person or via Skype.

In your photos there is no evidence of upper eyelid ptosis.  Ptosis surgery would not therefore be appropriate.  You may have the compensatory brow elevation due to the eyelid fold resting on the eyelid platform. I think you only need double fold surgery to increase the amount of visible eyelid platform.  Less is more. 

It is insightful of you to recognize the overuse of the forehead muscles to compensate for fullness in the upper eyelids. This is a common complaint of patients but not all can identify the origin of concern. Patients always have several options. One option is to do nothing at all but if this is a legitimate concern then doing nothing may not be the best choice for you. Of course there is always the option for surgery and cosmetic upper eyelid blepharoplasty is a great choice for a permanent solution. The third option is less invasive and temporary, as compared to surgery, but could yield the results you are looking for and that option Botox. The physician who provides your care should walk you through all options so you may make well-informed decision.

Undergoing any surgical procedure requires careful attention to detail and consideration for different options.  Consider obtaining several opinions before moving forward with any given procedure.

Trust your face to a board-certified facial plastic surgeon or a board-certified plastic surgeon with very extensive blepharoplasty experience.

You do not appear to have ptosis and it would be unwise for anyone to recommend ptosis surgery for you at this stage. The slight heaviness in your upper lids could be eased by a blepharoplasty possibly including raising the lid crease a couple of mm depending on the current position of your existing lid crease. Alternatively raising the brow may help but you would need a full assessment with an experienced plastic or oculoplastic surgeon to thoroughly evaluate your options. Your resting photo looks pretty good to me so it may even be best to leave things alone for a while.
