A chalazion is caused by a blocked meibomian gland. This causes an inflammatory lump (lesion), this is not an infection. Occasionally it can become secondarily infected.
The meibomian glands are located in your top and bottom lid margins and can be seen as tiny openings behind your lashes.
Many people with chalazions, particularly if they are recurrent, suffer from a condition called blepharitis. Blepharitis is a condition where the rims of the eyelids become inflamed. This is a very common complaint that can cause irritated, uncomfortable or gritty eyes. There is no cure for blepharitis but bathing of the lids is often helpful. This may also reduce your risk of developing a chalazion.
Other conditions such as rosacea, seborrhoeic dermatitis and dandruff may make you more susceptible to developing a chalazion.
If you normally wear contact lenses you will need to remove these prior to the procedure.If you are taking aspirin or any other blood thinners you will usually be able to carry on taking these. All herbal medicines should be stopped at least 14 days before surgery. If you are on Warfarin you should have an INR test within the 5 days before surgery and bring the result of this to surgery.You should bring a list of your current medications and any allergies with you.
You will not be able to drive yourself home after the procedure. Please arrange an alternative mode of transport or someone to help you.
The operation is carried out as a day case procedure so you will therefore be able to go home on the same day. The surgery itself takes approximately 20 minutes.You may already have signed a consent form or you will be asked to sign one on the day.
You will be taken into the procedure room where you will lie on a bed. The doctor will put anaesthetic drops into your eye, these will usually sting. Local anaesthetic is injected into your eyelid to numb the area. A small clamp is placed over the chalazion to allow the surgeon to see the inside of your eyelid. An incision is made on the inside of the lid, avoiding a visible skin scar. The contents of the chalazion are scooped out. You will have antibiotic ointment and a pad placed on your eye.
You may need to wait after the operation to ensure everything is OK. If you are in any discomfort take painkillers such as paracetamol or ibuprofen.
After washing your hands you may remove the pad 4 hours after the operation. It is normal to have blood staining on the pad. You may clean the area with boiled cooled water or sterile saline and clean cotton wool. You will be given an antibiotic ointment to use in the eye for 5-7 days after the operation.
If your wound begins to bleed, apply pressure to the area with a clean pad for 10 minutes. If the bleeding does not stop seek medical attention.
Avoid eye make-up for 5 to 7 days. You will have bruising around the eye. This will settle over the next 1-2 weeks.
Obtain medical help if you have severe pain, increasing swelling, redness or significant discharge. This could be a sign of infection.
