Squint surgery is the procedure carried out for the treatment of squint, a condition in which the eyes don’t align properly. Also known as strabismus, squint eyes occur usually due to muscle dysfunction, farsightedness, brain problems, trauma to the eye, or infections. It exists in children and adults. In children, the condition often results in amblyopia or lazy eyes and loss of depth perception. If the onset occurs in adulthood, it results in double vision. There are six muscles attached to the eye surface that are responsible for eye movements. When any one of these six muscles is imbalanced, it results in squinting. Squint surgery focuses on balancing these muscles (strengthen or weaken) to allow proper eye movements in all directions. The surgery can be carried out on one or both eyes depending on the patient.
