Chalazion

A chalazion (or "chalation") is a painless lump that forms on the upper or lower eyelid, which appears as a result of an accumulation of fat secretion in the sebaceous glands (Meibomian). When the chalazion affects vision, persists for more than two months, or increases rapidly in size, drainage may be required. This drainage is done through chalazion surgery, it is a simple and safe intervention that is performed under local anesthesia in a medical consultation.
