Meibomian gland probing is a procedure used to treat meibomian gland dysfunction (MGD), a common cause of dry eye disease, where the meibomian glands in the eyelid become blocked. These glands are responsible for producing the oily layer of the tear film, and when they become blocked, it can lead to insufficient tear production and symptoms like dryness, irritation, and discomfort.

The procedure involves using a specialized probe to open the blocked meibomian glands, allowing them to resume normal secretion of oils. This helps restore the proper balance of the tear film, improving eye lubrication and reducing dry eye symptoms.

Meibomian gland probing is highly effective for patients with chronic dry eye symptoms that do not respond to other treatments, such as eye drops. It can significantly improve quality of life for individuals with MGD.
