Is it possible to make tapered Asian eyes parallel, wider, and bigger with combined lateral Cantho+Blepharoplasty? (photo)

In order to significantly raise the eyelid margin a ptosis repair is required.The outer canthus can be raised with a canthoplasty/pexy if desired.Please consult in person with an experienced Board Certified Plastic Surgeon prior to making treatment decisions.

It is possible to create a crease and open the eyes more.  From the photograph it seems like you also have ptosis (low upper eyelids) which may need to be lifted to get the result you desire.  Remember you can't expect to look like someone else but an experience oculoplastic surgeon should be able to give you a nice natural appearance.  I'm not sure from the photo is a lateral canthoplasty is needed or only upper eyelid surgery.
