Can I change my middle eastern eyes into Asian eyes? (photos)

It is very important to understand that it is one thing to promise something.  It is quite another to deliver what was promised.  The photos of the individual you are referring to appear to be photoshopped.  I recommend caution.  It is basically impossible to achieve what you are looking for and the individual you cite appears to be using photoshop in making these claims.

You would probably benefit from an in person consultation with a plastic surgeon in Gangnam. Before consenting to surgery, you might consider fillers to try to make your eyelids look better (more Asian).
