Asymmetrical eyelids after Belpharoplasty, do I need a revision?

I've had my belpharoplasty 27 days ago. And now I find myself with a bigger crease on the right eye, andthus making the right eye lower and smaller than the left. When I try to open up my eyes wide, in the left eye, I can feel the muscles are strong and working together to finish the movement( the upper lid going up, the lower lid contracting downward), while in the right eye the muscles are weak, the lower lid hardly moves. Does this imply that I need a revision?
