Can I Change my Caucasian Eyes to Asian Eyes?

Looking at your eyelid at the moment the crease is slightly higher than what you seem to be wanting. It may be a challenge to make your eyelids look like BoA the Korean singer you've attached the photo there, but in principle there are things you can do to (for instance lowering the crease amongst other things) to make your eyelids look more to your desired shape. This certainly belongs closer outside the "typical" Asian eyelid surgery and I encourage you to find someone who has an interest in this subspecialty.
Wish you the best in your journey.

One needs to understand the anatomy of the Oriental eyelid and how it differs from the Caucasian eyelid. Caucasian eyelids have a fold about 1 cm above the lashes called the supratarsal fold. This is where the skin inserts into the deeper layers. In addition Orientals tend to have more fatty tissue in the upper portion of the eyelid and they also have an epicanthal  fold where the upper eyelid overlaps medially. I've never done this operation although I've done many operations going from Oriental to Caucasian. I would probably talk with a number of oculoplasticsurgeons before deciding if the procedure is right for you. You might start by injecting a dermal filler into the upper lids since this is a temporary procedure and just getting you the fullness may simulate the Oriental lid. I would think that once you release the supratarsal fold, you might be getting into a greater risk for complications, asymmetry, and permanent ptosis of the eyelid.
