1 week post chalazion draining in my lower left eyelid. Why has its size not changed after surgery? (photos)

I developed a chalazion in my lower left eyelid around 8 months ago. I was finally able to undergo a procedure to drain it a week ago. Since that's the case, why is my eyelid still the same size as it was before the procedure? The difference in size is clearly visible when I smile. Note: The red spot on the eyelid is a scar that was left over from a stye.
