An eye irrigation involves washing the conjunctival sac with a stream of liquid to treat various eye conditions. It is used to treat inflammatory processes of the conjunctiva, apply medication with an antiseptic effect, remove foreign objects or chemicals from the eye, and apply heat or cold. The procedure involves cleaning the eyes with sterile cotton balls and then irrigating the eye with a sterile solution like saline or an antiseptic using a device like an intravenous can or dropper to direct the flow. The patient lies on their side and the eye lids are held open while fluid is directed into the conjunctival sac from the inner corner of the eye.
