How long does chemosis last?

Chemosis is the swelling of the conjunctiva (the mucous covering of the eye.) It occurs on occasion with lower eyelid surgery. Treatments often tried are cold compresses, chilled artificial tears and steroid eye drops. It usually resolves within a few weeks, but some more severe cases may last for a few months. 

After eyelid surgery, fluid can accumulate under the conjunctival lining of the white portion (sclera) of the outer eye. Called chemosis, this can feel like a water blister and is annoying. It usually subsides in time but may last several weeks. Occasionally it requires a bit of physician assistance to resolve.

We think that chemosis is due to a blockage of the lymphatic drainage system after the surgery.  For many people, the chemosis will resolve fairly quickly with artificial tears and ointments to keep the eye well lubricated.  At times it can persist, and other treatments may be needed.  You should see an oculoplastic surgeon for help if it doesn't resolve quickly.  Unfortunately there is no easy way to get rid of it!
