1.5 years post op Asian eyelid surgery, eyelid crease is too high and unnatural. Revision options? (photos)

I agree. The crease is slightly higher and puffier than usual. The usual analysis of this kind of eye known as "sausage eye".
The crease can be lowered quite easily by revision surgery and puffiness may be due to residual muscle rather than fat.
No fat exists below the crease but Asian muscles are somewhat thicker than Caucasian muscles;this muscle can be removed without affecting eye function.

Your crease is too high for an Asian ideal and you also have fullness in your lower lids which was not trimmed down during your operation.  The result that you see is that result you should expect going forward.  It can be fixed with revision surgery.  Hope this helps.

Your are correct in that waiting over a year should give you plenty of time to know the final result of your surgery. If you are not happy with the result, I would suggest bringing old photos before your surgery of yourself, as well as any pictures of what you think would be your desired look. To answer your questions: You can lower and eyelid crease. Removing fat may give you an even more caucasian look. If you have allergies, this can contribute to swelling at this point as well. Best to have a consultation with a physician who specializes in eyelid surgery with experience in Asian eyelid surgery for a complete exam an review of photographs. Hope this helps.
