Eye Floaters from very aggressive lower blepharoplasty?

Just because you had chemosis and sunconjunctival hemorrhage does not mean you had an "aggressive" surgery.  Both of these can occur after any lower eyelid surgery.  If you did have a lot of bleeding, this may be why  you had more hematoma post-op.  Floaters occur with a posterior vitreous detachment.  This is more common with age, and in people who are very near sighted. It can also occur after trauma directly to the eye.  when we do a lower eyelid surgery there is a lot of manipulation of the lid, but the eye itself is not touched, so this should not have caused your floaters.
