Surgery to Make Non-Asian Eyes Bigger?

There are several surgical techniques to make one's eyes bigger. The most important thing is to ensure a natural appearance rather than an artificial look or bugged-eyed result. See an eyelid specialist ( oculoplastic surgeon ) to achieve the best results. 

Hi there,
Without seeing any photos, it's difficult to advise most suitable procedures that will make your eyes look bigger.
Understanding peri-orbital aesthetics with reference to an optimal facial harmony is the key to deciding what treatment options that will be ideal for your eyelid enhancement in achieving the perception of a "larger eyes" effect! There are a multitude of surgical and non-surgical options that can work synergistically to achieve your desired effect but it'll also be guided by your expectation of what "bigger" eyes mean to you.
I strongly advise you seeing a qualified Specialist Plastic Surgeon for further in depth discussion.
Best wishes

Each patient is unique. Patients with heavy eyelids or brows may benefit from upper eyelid surgery or a brow lift in order to open the eyes and improve the appearance of the upper face. Patients with eyelid ptosis or drooping may need ptosis repair to open the eyes more.
Be sure to see an expert for a formal evaluation and treatment recommendations.
All the best,

Thank you for your question. Often times soft tissue procedures such as blepharoplasty can help. One must be careful though as the lid coverage of the eye is very important and keeps the cornea healthy. Best of luck!DrC

The real answer to your question can only be determined by an in-person consultation. However, eyes often appear to be small owing to excess skin on the eyelid or a droopy brow. Each of these is easily remedied with either upper blepharoplasty or a brow lift. The goal would be to reveal more of your eye while keeping your expression relaxed and natural. This takes a great deal of skill, so please take your time finding an expert to help you. I hope this helps.
