Is there a way to correct narrow eyes?

Please post a photo of your eyes so I can better help you (or you can email to my office). What you are describing may or may not be possible.

You did not post photographs.  Your cosmetic concern needs to be evaluated in the context of what is normal and what is reasonable.  That should always be part of the consultation and discussion.  Do you have a reasonable concern or do you have body dysmorphia?  What you are proposing with fat will harm your appearance.

This is difficult to answer without pictures. A combination of Botox with fillers and ultherapy could be used to lift the brow making them appear more wide-set. I recommend getting a formal evaluation with a cosmetic dermatologist for a formal evaluation. Best, Dr. Emer

There are surgeries for pathologic narrow eyes, with functional purposes, not for aesthetic improvement. If you have a limited visual camp, then you can be candidate for those interventions. If you are searching for cosmetic, then surgeries or procedures on your eyes and/or brows can let you looks with more expressive and open eyes. (but without change really the narrow of your eyes)

It is possible to rearrange the school and bring the ice further apart but this is an operation you do not want to undergo nor was anyone probably take it on.
These procedures are for children who are born with skull deformities.
I suggest consulting with a board-certified plastic surgeon and have a complete facial analysis done to see what type of procedures may help to give you an overall more balanced look.
Of course with that posting a photograph it's difficult for anyone of us to give you any real suggestions.
