Uneven eyelid after upper blepharoplasty 1.5 month post-op. Will it even out? (Photos)

They will probably level out after several more months, to the point where you may not need to do anything further. The incisions themselves look uneven, which is often an error in measurement, but in some cases they result from purposeful asymmetric skin excision (to compensate for uneven brow position).

The asymmetry is likely due to untreated eyeball position asymmetry with right eyeball more protruding than left. Examination is required to determine exact cause.

Hi Janabelle24,When your eyes are open, the lids appear pretty symmetric.  When they are closed, you can see that the incisions are at different levels. This may be because the natural creases were originally at different levels to begin with.  This is normal.  And the area usually heals such that the incisions are barely discernible, blending into the surrounding skin.For further concerns, follow with your surgeon.Best wishes,Dr. Jay

There is really no excuse for the two creases being so asymmetric.  The good news is that these do hide when the eyes are open. You need a detailed personal assessment to full understand all of the factor at work here giving you the appearance you have and how best to address these problems.  I suspect that you will need a crease lowering anchor blepharoplasty to support the upper eyelid lashes.  I recommend letting the eyelids heal for another 6 to 8 weeks before having this consultation. 

its best to discuss your concerns with your surgeon.  Perhaps that was a good reason why your incisions are so different from one lid to the other.  Your creases are a direct reflection of where you incisions were placed so you can also ask your surgeon what he/she can do for you under the revision policy that your surgeon should have.

Hi and thank you for reaching out. Your photo shows a significant asymmetry of upper eyelid crease position. In your case, a surgical revision may be necessary to improve this, and I would recommend that the eyelid with the lower crease be revised. 
Here’s why: The one crease that is higher is already too close to the brow and the total length of skin between the brow and the lashes is shorter on that side as well. For those two reasons, I would not recommend the revision be performed on this side. 
The eyelid with the lower crease has a bit more skin overall (lash to brow) and the length of the skin remaining above the crease is greater as well. Removing a bit more skin above the crease on this side, especially sooner rather than later so that the final scarring has not yet set, would raise the crease position some and reduce the crease to brow distance, thus improving the overall symmetry between the two eyelids. 
Best of luck! Dr Elba Pacheco
