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!

It somewhat depends on what has caused it and how bad it has gotten.  Think of it as part of the bruise that occurs after surgery.  However, dry eye and exposure of this delicate tissue also play a role.  This means that if the tissue is swollen enough that is pokes out between the eyelids, the swelling can persist for a very long time.  Aggressive lubrication with ointment and artificial tears can help.  If this proves to be a persistent issue, ask your surgeon to refer you to an oculoplastic surgeon for management help.

thank you for your question. It depends on the cause of the chemosis, and if it is improving. I would recommend you stay in close contact with your surgeon. eye drops and lubrication help, but if there is no improvement, more may be necessary. sometimes, taping the end of the eyelids upwards can support the swelling if present on the lower eyelids.
