Chalazion excision is a minor surgical procedure used when a chalazion—a painless, firm lump in the eyelid caused by a blocked oil gland—does not resolve with warm compresses and conservative treatment. The goal of the procedure is to remove the trapped inflammatory material, reduce eyelid swelling, and restore normal eyelid contour and comfort.

​

How chalazion excision works is by numbing the eyelid and making a small incision, usually from the inner surface of the lid, to drain and remove the contents of the chalazion. The procedure is quick, typically performed in the office or outpatient setting, and does not usually require stitches on the skin. Mild swelling or bruising can occur afterward, but recovery is generally rapid with good cosmetic results but there can be recurrence.
