How long does chemosis last?

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.
