Is there surgery to widen the distance between the eyes of closed set eyes?

There are surgeries for this which are performed by craniofacial surgeons but it is generally reserved for cogenital deformities and not for "cosmetic" indications. It involves surgery which may closely approach the brain and optic nerves.

you would need major craniofacial surgery (cutting the facial bones and repositioning them with plates and screws) to accomplish wider-set eyes.  Your best bet would be to learn some makeup tricks to create the illusion of more wide-set eyes.

To do what you want would require major craniofacial surgery and would be way to expensive and potentially dangerous to take on for what you are wanting.
