Strabismus Eye Surgery is normally performed on children over four years old and adults who are suffering from this visual defect. The surgery is fairly simple with satisfactory results: the look is enhanced, and the visual field is improved significantly.



Strabismus is a condition when both eyes are not looking at the same thing at the same time: one of the two eyes stares at you while the other looks either towards the nose or towards the outside. In normal vision, the eyes are straight when they fix the same point and so the brain can transform the two images into a single three-dimensional one. Strabismus occurs most often between the ages of 6 months and 3.5 years. Any permanent strabismus from birth, or even intermittent after the age of 4 months, requires specialist treatment and probably surgery.


The consequences of strabismus condition

The consequences of strabismus vary. If it appears in early childhood, it can lead to Amblyopia of one eye mostly known as “lazy eye syndrome”, which is a defect in the development of a vision of the eye. If it appears later, strabismus can cause double vision (called diplopia). In adults, a neurological or orbital anomaly or a general pathology may be the cause of strabismus. The practitioner will start with an examination to detect the cause in order to offer treatment or surgery.

There are several solutions to treat strabismus: first, in children, the ophthalmologist would normally prescribe rehabilitation of Amblyopia. In severe cases, an operation is needed. 


Strabismus Eye Surgery

The objectives of surgery are varied: satisfactory aesthetics, improvement of the visual field, elimination of double vision, and/or improvement of binocular relationships.

It is possible to operate at any age, including late adulthood, even if one or more operations have already been performed. However, most strabismus is operated on between 2 and 6 years old. It is often best to perform the surgery before elementary school if the strabismus is severe.


How does the Strabismus Eye Surgery work

Strabismus surgery works on the muscles of the eye by moving them to recenter the eye. It is performed under an operating microscope, lasts 10 to 45 minutes depending on the number of muscles to be operated on. It will consist of weakening muscles that are too strong and strengthen muscles that are too weak in order to find a balance of muscular forces that allow straightness and alignment of the ocular axes.


The day of the surgery

Hospitalization is generally carried out on an outpatient basis, meaning that it is not necessary to spend the night at the clinic. If the medical conditions require, it may however sometimes be necessary to return to the clinic the day before and/or to leave the day after the operation. For children, it is then advisable that a parent sleeps there.




Strabismus surgery involves sewing the eye muscle to the wall of the eye after altering the insertion position and/or the length of the muscle. Standard strabismus surgery (no adjustable suture) utilizes a permanent knot tied during the surgical procedure.

The success rate of each surgery is always the same, 60-80 percent. Strabismus surgery to correct the eye position is a commonly done procedure. It does not involve cutting into the eyeball, nor does it require that the eye be “taken out” in order to reach the muscle.

Depending on the type of eye muscle surgery you need, this surgery can take from 45 minutes to 2 hours. Recovery from anesthesia may take several hours.

uous activity, such as lifting or contact sports for 14 days following surgery. Sleep with your head elevated on 2 to 3 pillows for 5 to 7 days to reduce pain and swelling. Avoid swimming and activities in which sand or dirt may enter the eye for 14 days. There are no restrictions on reading or watching TV.
