Squint surgery is performed when your eyes are not straight or you have a problem with double vision. It is a complex area of eye surgery and it is possible to have eyes that aren’t straight with no symptoms of double vision.
Where the neural processes to keep the eyes straight are poor, successful squint surgery may work well for some years but in reality there is always the possibility that further surgery may be necessary.
Surgery may also have to be staged if the misalignment involves a combination of directions.
Surgery is most commonly performed as a day procedure under a general anaesthetic. Occasionally local anaesthetic may be all that is necessary. The surgery involves altering how the muscles are attached to the eye. It may be necessary to operate on both eyes to correct a squint, for example, if the eye has a very large turn.
After the surgery there may be some double vision. Usually this resolves over the following weeks. The eyes do appear red but discomfort is not usually an issue.
