Swelling can take months
Swelling can take months to fully resolve, so it's best if you wait a little longer before you assess your results.
Swelling is to be expected one week after eyelid surgery.
Swelling will week after eyelid surgery is completely expected and may be of varying amounts. If you have concerns about your eyes in particular you should discuss this with your own surgeon.
One week post up eyelid surgery
At one week post-op you should still have significant swelling and possibly bruising. This is quite variable. The swelling from the lower lid will often move into the upper as well. You will notice a change in the shape of the eye at this point, but as time goes on it should look more normal. If you had a cosmetic surgery done on the lids, I certainly hope that they look a little different than they did before the surgery.
Yes lower eyelid surgery can cause the upper eyelid to swell.
Here is another secret: Eyelid surgery takes more than 2 weeks to heal. One or two weeks is not very much time after eyelid surgery. It can literally take a couple of months or more for most of the swelling to resolve. It is true that the eyelids do dramatically change in the first few weeks. It is hard being patient. Hang in there.
