Surgeon Accidentally Cut Levator Muscle During Bleph Revision

Three weeks ago during bletharoplasty revision my plastic surgeon accidently cut my levator muscle. When my eyelid would not open the next day he stitched it up in his office. Since then my eyelid doesn't look normal, it's pulled and the eye is open so wide the full iris is apparent unlike the other eye and the lid doesn't close fully. Yesterday I went to an opthalamic surgeon and he said he could release the taught eyelid. My surgery is in 3 weeks. Have I waited long enough?
