This module describes how to incise and drain a Meibomian cyst (chalazion).


  1. Meibomian cyst with failure of


  1. Uncooperative patient

  2. Large meibomian cysts obscuring vision

  3. In the elderly, where malignancy is suspected


Always verify your patient’s identity and obtain informed consent before proceeding.

How do I explain this procedure?

“There is a small swelling on your eyelid because of a blocked gland. We call this a Meibomian cyst. It is necessary to remove it because it can get bigger or become infected.”

What can my patient expect?

“I will place drops in your eye to numb the eyeball and then put a small injection in the eyelid to numb the eyelid. After that I will turn your eyelid inside out, which will not be painful and not too uncomfortable. I will then place an instrument to shield your eye and make a small cut in the eyelid to drain the cyst.”

What is my patient’s role?

“Let me know if you have any allergies, a heart condition, or a bleeding tendency, or use blood thinners. Fearing blood or needles is normal, but tell me if you have fainted from it. Please look up while I instil the drops and while I put the injection into the eyelid. After that, please try to remain very still during this procedure.”

Documentation

  1. Patient notes

Equipment

  1. Alcohol-based hand rub

  2. A surgical or waterproof marker

  3. A 3-5 ml syringe, aspiration needle (ideally blunt fill), and a small injection needle

  4. Lignocaine 1% without adrenaline

  5. An alcohol swab

  6. (0.5% proparacaine eye drops)

  7. Dressing pack

  8. Aqueous povidone iodine 5%

  9. Eye drape (optional)

  10. #11 blade

  11. Scalpel handle (optional)

  12. Small curette

  13. Fine toothed forceps (required if removing pseudocapsule)

  14. Fine scissors (required if removing pseudocapsule)

  15. Cautery (preferable but not always required)

  16. Antibiotic ointment (eg. chloramphenicol 1%)

  17. Two eye pads

  18. Tape (eg. micropore)


The patient can be seated in front of you, facing forward with the head preferable against the wall, but it is easier and safer if the patient is lying on a bed facing the ceiling. Always position good lighting on the site, and

can be useful.


Follow medical asepsis with sterile gloves.

  1. Perform hand hygiene.

  2. Locally anaesthetise the eye by instilling topical anaesthetic drops into the eye.

  3. Draw the outline around the lesion with the marker.

  4. Open the suture pack to create a sterile field and pour skin disinfectant into the well. Open the needles & syringe, clamp, curette, forceps, scissors, scalpel blade and dressing onto the sterile field.

  5. Perform hand hygiene and don gloves.

  6. Apply

    5% preparation to the eye and lids and drape the site.

  7. Ask an assistant to clean the rubber top with an alcohol swab and hold up a bottle of lignocaine without adrenaline. Draw up 2-3 ml. Put the chalazion clamp under the eyelid (between the lid and the eye) to protect the globe against accidental penetration, and infiltrate lignocaine into the

    surrounding the chalazion.

  8. Insert the chalazion clamp with the ring on the tarsal conjunctival side and the solid part of the clamp on the skin side of the eyelid.

  9. the clamp to restrict bleeding, and evert the eyelid to present the conjunctival surface . Take care not to injure or damage the skin or conjunctiva (if the clamp is tightened too much).

  10. Identify the blocked Meibomian gland on the tarsal surface.

  11. Using a #11 blade, make a vertical incision perpendicular to the lid margin into the bulk of the chalazion contents on the

    of the eyelid.

  12. Use a small curette to scrape out the contents of the chalazion.

  13. If a

    is identified, use the forceps to grasp and then gently excise this tissue using the scissors.

  14. Once the excision is complete, release the clamp. Control any bleeding with direct tamponade, or, if necessary, cautery.

  15. Apply chloramphenicol ointment 1% and a firm double pad to the eye. Instruct the patient to remove the eye pads after 4 hours.

  16. Further instruct the patient to use lid cleaning including hot compression, massage and scrubs in order to reduce recurrence.

  17. Dispose of medical waste safely.

  18. Document completion of the procedure in patient notes.


The patient feels pain from the clamp.

More infiltration of local anaesthetic is required.

I do not have a chalazion clamp.

Continue conservative treatment until one can be procured, or refer the patient on conservative treatment.
