Would lateral canthoplasty be the best option for my eyes? (Photo)

For this reason, I would strongly discourage you from doing this to yourself.  You have other issues associated with your eye and it is possible that these are the source of your concerns.  This includes the under eye hollow, the extra fold of skin in the lower eyelids.  The upper eyelid also a bit ptotic.  The skin in the upper eyelid is a bit loose over the platform.  In short, you could benefit from a well designed eyelid surgery that dies not include a canthoplasty.  

Looking at your photos I don't think a lateral canthoplasty will give you what you are looking for.  Although often in person the exam is different than in a photo.  The eyelids are moving, dynamic structures and are best evaluated in person.  I am on oculoplastic surgeon, with specific training in eyelid position.  It would be my pleasure to examine you in person and give my opinion.  Good Luck.

You are already ahead of the game since your right lateral canthus is higher than your medial. It would be my privilege to examine you in person to have a close look at both eyes as they relate to the rest of your face. Remember, less is more. Understatement wins the day.Sincerely,
