Individuals who have a negative canthal tilt can I have a little bit of a sad appearance around their eyes. Any shape on the face that has an upward curve like a smile shape tends to give a more positive look. Changing the canthal tilt is fairly complex and involved. The angle your eyeballs are set in your skull is primarily determined by bone structure and how your orbital socket developed. It’s not easy or straightforward surgery and I’m not sure it’s something worth pursuing unless it’s really needed. You can consult with senior oculoplastic surgeons in your community to see what they have to say, but I would approach surgical intervention with a bit of caution. From the limited picture you’ve included you have a very attractive, desirable youthful face that I think most people should be proud of. My best recommendation is to give you reassurance and probably steer you away from surgical intervention. Best, Mats Hagstrom MD
