You suffer of one or more chalazion(s). As treatment for this condition, your ophthalmologist proposes surgery.

This document contains the information about the reasons, conditions, results, risks and limitations of the proposed medical act.

The Chalazion

It is a more or less hard abscess following chronic infection of the glands of MEIBOM or other glands found in the thickness of the eyelid.

Why operate?

Without effective treatment, the lesion may regularly recur in the same gland and/or extend in the neighbouring glands and invade other surrounding tissue.

Surgery is the only way to make it disappear.

The operation

It is performed on the patient, while installed on the back, in a sterile environment, under surgical microscope.

* Anaesthesia: it is done by an injection of anaesthetic in the vicinity of the lesion.

* Technique: The operation involves the total excision of the lesion. Chronologically, the steps of the procedure are:
Disinfection, anaesthesia by an injection in the area of the lesion, incision, removal of the abnormal tissue, debridement of the healthy tissue, exceptionally closure with stitches, disinfection and, sometimes, eye pad or eye-cup.

Your ophthalmologist will decide the type of anaesthesia, closure and post-operative treatment depending on the location and size of the lesion.

The time spent in the operating room is 10 to 20 minutes. In the operating theatre, it is of an half an hour. In short, you leave one hour after your arrival.

Any stitches will be removed 1-2 weeks later.

If the lesion has an unusual appearance, an analysis in the laboratory of pathology can be performed to determine its exact nature. It is your responsibility to reconnect, 1 to 2 weeks later to have the results. The cost of this analysis will be billed by the laboratory.

Usual postoperative course

The postoperative course is simple and last 1 week: slight haematoma, light swelling, mild to moderate pain and redness of the eyelids. Unless stitches on the skin of the eyelid had to be put, there is no scar.

Complications of the operation

Although it is perfectly standardized and followed by good results, this type of operation is no exception to the general rule that there is no surgery without risk. It is not possible for your ophthalmologist to ensure formally the success of an intervention.

You should be aware that

* During the anaesthesia and sometimes despite the anaesthesia, during the operation itself, there is a hazard of discomfort and, although very rarely, even pain. This risk depends on the patient’s responsiveness to the anaesthetic molecule. It is unpredictable.

* In any local anaesthesia and all surgical procedures, there is a hazard of local complications, bleeding and infection and general intolerance that can lead to a severe shock. The risk of these complications is unpredictable. It
is so exceptional that it is impossible to quantify.

* After any removal of abscess, there is a hazard of recurrence that may lead to further surgery. This risk is unpredictable, unusual, non quantifiable.

To what must the patient be careful to, before, during and after the operation?
You agree to follow the precautions, treatments and appointments to be prescribed before, during and after the operation.

THE EVE OF THE OPERATION: Remove make-up; thoroughly wash your hair and face, especially the eyelids and eyelashes, and the whole body with shampoo or soap. Rinse generously and repeat the same thorough washing and rinsing. Dry yourself
with a clean towel. Sleep with clean nightclothes and bedding. It is advisable not to take any Aspirin the day before and the day of the operation. You may take it the day after. Discuss already now this matter with your GP.

THE DAY OF THE OPERATION AND DURING THE WEEK FOLLOWING IT: On the morning of that day, upon awakening, re-remove make-up carefully and repeat a thorough double shower as described above. Wear clean underwear and clothes. Take your breakfast and regular medications, except Aspirin. Make sure you have with you all your medications and this document duly signed.

Then go, at the time indicated in your appointment, to Dr. SAFFIEDINE’s Cabinet to register and pay all the medical and surgical costs of that day. These fees will not be reimbursed by the Social Security. They will eventually be reimbursed by your private insurance to which you should check. The Cabinet of Dr. SAFFIEDINE is not involved in these processes.

During the operation, you are requested to keep calm and strictly follow the instructions given by your ophthalmologist.

After the operation, use the eye drops or ointment prescribed on the operated eye at noon, evening and before bed. The application of this treatment is to be continued four times a day (morning, afternoon, evening and before bedtime) during a whole week.

The presence of an aiding person is advised during the remainder day of the operation.

A little bleeding and swelling (haematoma) of the eyelid should not worry you or keep you from following the treatment.

In case of pain, take one or two, maximum three, Paracetamol tablets per day for up to three days. Avoid Aspirin.

It is always strongly advised not to rub your eyes.

If a protective eye-pad or an eye-cup is placed on the eye, it should be kept throughout sleep, nap or at night, changing the plasters for each application of ointment, all this for 7 days. The plasters stick best on a skin previously washed with soap or a gently rubbed with an alcoholic perfume.

Visual activities, professional and of leisure, are all allowed as long as there is no eye contact with dirt or dust.

Wearing sunglasses is always advisable when exposed to sunlight.
