Please see the following link for detailed information on how to possibly achieve more almond shape eyes. Canthoplasty may do it or it may require additional concurrent step to achieve the goal.

However, yes you can have help for this upper eyelids and thoughtful lateral canthoplasty can help.  However, you are asking for a level of surgical accuracy that is beyond the level of work that most surgeons do.  For that reason, I suspect that you will be very disappointed with surgical results unless you really do your homework and find a top aesthetic reconstructive eyelid surgeon.
