I Have Vertically Large Eyes but Horizontlly They Are Really Small Can a Surgery Help Me Lengthen my Eye Horizontally?

It may very well be that eyelid surgery to change the shape of your eyes might be helpful.  However you diagnosis many or may not be correct.  Also it is critically important that your potential surgeon truly understands you concerns.

It may or may not be possible, depending on your exact anatomy, age, ethnicity.  A photo would be useful.  Consult an oculoplastic surgeon.

It is possible do lengthen the eyelid aperture horizontally via a canthopexy/canthoplasty procedure, but you should understand that the end result may not look very natural. Those procedures work best in a reconstructive setting, but if done for aesthetic reasons like you propose, you may end up quite unhappy. And it will be a situation were reversal may be near impossible.

 

Think twice about this surgery, but if you'd like to post a photo, we can give you a more accurate recommendation.
