A chalazion is a small, painless lump or swelling that develops on the eyelid due to a blocked oil gland (meibomian gland). It often appears as a firm, round bump on either the upper or lower eyelid. While chalazions are not usually painful, they can become red, swollen, or cause vision obstruction if they grow too large.
Chalazions are not the same as a stye (hordeolum). A stye is an infected gland that is usually painful, while a chalazion is a non-infected blockage that develops more slowly.
A chalazion forms when the meibomian glands, which produce the oily layer of tears, become clogged. Common causes include:
Most chalazions resolve on their own within a few weeks, but treatment can help speed up healing.
If a chalazion (eyelid lump) does not go away with home treatments like warm compresses, or if it grows too large, affects vision, or becomes chronically inflamed, a doctor may recommend chalazion removal surgery. This is a quick and minimally invasive procedure to drain or remove the blocked gland.
Surgical removal is considered if:
The chalazion does not improve after 1-2 months of warm compresses and medication.
It grows too large and presses on the eye, causing blurry vision.
The chalazion becomes chronically inflamed or infected.
You experience frequent or recurring chalazions on the same eyelid.
A chalazion is a small, painless lump on the eyelid caused by a blocked oil gland (meibomian gland). It can become swollen, red, or cause vision issues if it grows too large.
Surgical removal is recommended if:
The chalazion does not go away after 1-2 months of warm compresses.
It grows large enough to affect vision.
It becomes chronically inflamed or keeps returning.
No, local anesthesia is used to numb the eyelid, so you won’t feel pain during the procedure.
The surgery takes 10-20 minutes and is done as an outpatient procedure.
No, the incision is usually made inside the eyelid, so there is no visible scar.
If your chalazion does not improve with home treatment or keeps returning, consult an ophthalmologist to discuss removal options.
