Squints (Strabismus) - Preparing for surgery

Why is this procedure needed?
The aim of the procedure is to re-align the eyes so as to either:

  1. Improve the ability of the eyes to work together (improve binocularity), or
  2. reduce or eliminate double vision, or
  3. reduce or eliminate an abnormal head position (e.g. head turn or tilt), or
  4. improve the appearance of the patient

What does it involve?

  1. There are many different surgical procedures depending on the type of squints.
  2. The procedure may be done under general anaesthesia (i.e. with the patient fully asleep); or under topical anaesthesia (i.e. with eye numbing eye drops) in older, co-operative patients.
  3. An incision is made on the conjunctiva (i.e. the transparent layer of membrane covering the white part of the eye) and eye muscles are located under this membrane, and repositioned (i.e. either moved or shortened).
  4. Absorbable sutures are used in most cases and these will dissolve, without requiring removal, in two to three months. Non-absorbable sutures may also be used in special circumstances.
  5. The conjunctiva is then repositioned over the surgical site with absorbable sutures. 

What precautions must be taken before the squint operation?
Please inform your doctor if your child has any medical illnesses.

  1. A history of allergy or reaction to any medications, drugs, or food.      
  2. A history of bleeding or clotting disorders, or if your child is taking any drugs or herbs that thin the blood (e.g. warfarin, aspirin, ticlopidine, or clopidogrel), which may increase the risk of bleeding.
  3. Inform the doctor if your child is unwell a few days before surgery.
  4. Adhere to the fasting guidelines provided.
