Asymmetrical Eyelids After Blepharoplasty

This is still too early to draw any long term conclusions about the final result.
If this is a double eyelid surgery then occasionally the swelling on the eyelid can persist. However, there are numerous other causes which should be evaluated by your surgeon prior to drawing any conclusions.
These can include:

edema (swelling)
lymphatic obstruction
stye/chalazion obstruction of eyelid structures
mechanical factors (sleeping with your head towards the right side)
previous scars
infection
dry eye syndrome
inflammation
chemical irritation
numerous other causes

Discuss this with your surgeon but be patient. Occasionally there are some dimple solutions that depend upon the cause. From your pictures it looks mild and is likely to resolve without any additional treatment. I would advise you against seeking any revisions at this point in time and do not feel it will be necessary.
Take care! I hope this hleps

I actually think your result looks quite nice.  Asymmetry is quite common in all eyelid surgery, especially if there is asymmetry preoperatively.  Your asymmetry is minimal and although it may be addressed with a revision, I think at eight weeks it is too soon.  

the right eyelid still looks swollen.  i would wait until the swelling completely resolved before making a decision on revision.  if a revision is needed, generally only the right eyelid would need revision.

 if this condition persists, you may have ptosis of the right eyelid that was not addressed with your initial surgery.  this means one of your eyelids is lower than the other, a very common finding in most people.  this can be corrected fairly simply using a non-incisional method such as a Muller muscle tuck or an incisional method such as levator plication or levator advancement.  all of the surgical techniques tighten the muscles that determine the position of the eyelid so that the eyelid will be in a higher position.my preference in cases such as yours is to tighten the muller muscle with a suture, a technique called non-incisional ptosis repair, using the same strand of suture that is used in a non-incisional double eyelid fold creation, to create the fold and lift the eyelid higher.  this technique is uncommon in the US and was developed in Korea, where asian eyelid surgery is the most commonly performed plastic surgical procedure.
