Incision and curettage for chalazion

If you have been told you need chalazion drainage, the procedure has a long name — incision and curettage — but it is a small, in-office step. The key point for most patients is that the cut is made on the inside of the eyelid, so chalazion drainage usually leaves no visible scar on the skin.

What is a chalazion?

A chalazion is a firm, usually painless lump in the eyelid caused by a blocked meibomian oil gland. The gland’s oil backs up, the surrounding tissue becomes chronically inflamed, and a rounded bump forms deep in the lid over weeks. It is not an infection, which is why it often needs time or a procedure rather than antibiotics. For a broader overview, see our guide to chalazia and our page on eyelid bumps.

What is incision and curettage?

Incision and curettage, often shortened to I&C, is the standard surgical treatment for a chalazion that has not resolved with warm compresses. The name describes the two steps: an incision is made to open the lump, and a curette is used to clean it out. The goal is to remove the blocked, inflamed material so the gland can settle and the lid can return to normal. It is done in the office under local anesthesia and usually takes only a short time once the lid is numb. Most patients go home the same day and resume normal activities soon after.

Chalazion drainage: step by step

The steps are predictable, which is usually reassuring. A typical procedure looks like this:

1. Numbing eye drops are placed, then local anesthetic is injected around the lump so the lid is numb.
2. The lid is gently turned outward (everted) so the inner surface faces up.
3. A small clamp is placed around the lump to steady the lid and to shield the eye.
4. The surgeon makes a small vertical cut on the inner surface of the lid, over the lump, parallel to the oil glands.
5. The blocked, granular material often bulges out through the opening.
6. A curette — a small spoon-shaped instrument — is inserted and used to scrape and scoop the material from the walls of the lump.
7. Pressure is applied to stop any bleeding, the clamp is removed, and the lid is turned back into place.

The cut is made on the palpebral conjunctiva, the smooth lining on the inside of the lid, rather than on the skin. That is the whole reason the outside of the lid is left untouched.

Why the inner cut leaves no visible scar

Scars form where skin is cut. In this procedure the skin of the eyelid is never cut; the incision is on the inner lining, which heals quickly and is hidden from view. The oil glands run vertically inside the lid, so the cut is made parallel to them to avoid disrupting their structure. The surgeon also stays a few millimeters away from the lid margin to avoid notching the edge of the lid. For most patients the only outward sign afterward is mild bruising or swelling that fades over days. The inner lining heals quickly because it is moist and well supplied with blood. The outer skin of the lid, by contrast, is never touched, so there is no external incision to care for and no stitch line to worry about. This is one reason the procedure appeals to patients who are concerned about appearance.

Drainage vs steroid injection at a glance

When is drainage chosen over other options?

Not every chalazion needs drainage. Warm compresses resolve many within weeks, and a steroid injection is another office option. The choice depends on the lump’s size, texture, and how long it has been present. Drainage is often chosen when:

• The lump has persisted for weeks despite compresses
• The lump is solid or granular rather than soft
• The lump is large enough to press on the eye or blur vision
• The lump looks atypical or recurrent, so a sample should be examined
• The patient prefers a single, definitive step

Your eye doctor weighs these factors. For a comparison of the two office procedures, see our page on steroid injection for chalazion.

What to expect afterward

Preparation is simple: follow your surgeon’s instructions, which may include pausing certain blood thinners only if your doctor advises it. Do not stop a prescribed medicine on your own. Arrive with clean skin and no eye makeup, bring a list of your medicines and allergies, and arrange a ride home if there is any chance of sedation. Recovery is usually quick. The lid may be tender, bruised, or slightly swollen for a day or two. Your surgeon may suggest cold compresses and a brief course of antibiotic ointment. Most people return to normal activities soon. A follow-up visit confirms that the lump has resolved and the lid is healing. If the lump returns in the same spot, it should be examined again; recurrent lumps are sometimes sent for testing to rule out other conditions.

When to see a doctor

Contact your eye care professional promptly if any of these occur:

• Vision changes or blurry vision in the affected eye
• Redness or swelling that spreads beyond the lid
• Fever
• Pain that is severe or worsening
• A lump that bleeds, ulcerates, or breaks through the skin
• A lump that keeps growing despite care
• Bumps that recur in the same spot

FAQ

What is incision and curettage for a chalazion?

It is a minor office procedure that drains a chalazion. The surgeon makes a small cut on the inner eyelid, then uses a curette to scrape out the blocked material.

Does the procedure leave a scar?

Usually no visible scar, because the cut is made on the inner surface of the eyelid. The outside skin is not cut.

Is chalazion drainage painful?

The lid is numbed with local anesthesia. You may feel pressure and movement, but not sharp pain. Tell your surgeon if you feel real pain.

How long does recovery take?

Most people have mild tenderness for a day or two. Your surgeon will give you a simple aftercare plan and a follow-up appointment.

When is drainage preferred over injection?

Drainage is often chosen for lumps that persist, are solid, or look atypical. Your eye doctor decides based on the lump’s size and history.

Can a chalazion come back after drainage?

Yes, recurrence is possible. A lump that returns in the same spot should be examined again, and recurrent lumps may be sent for testing.
