It's possible that this represents a hematoma. As long as your vision is not impaired and the wound has stayed closed, it should be fine to wait and watch. Any blood collection (hematoma) should gradually go away. If you have a scratchy feeling in your eye, you can try artificial tears. If that doesn't make your eye feel better or if your vision seems to be affected, you should have the doctor take a look at your eye.

Warm compresses are often soothing, and could potentially help the hematoma resolve faster. Usually it's just a matter of time. If you can see the incision, it sounds like you had a subciliary (skin) approach to the eyelid surgery.
