Squint Surgery

Home > Squint Surgery

Squint, often referred to as strabismus, is an imperfect eye alignment. This may result in the eyes pointing in various directions, which can lead to double vision and other visual problems. One or both eyes may squint, and it may be continuous or irregular.


There are various squint types, including:

  • Esotropia: When the eye bends inward toward the nose, it squints. Children are more likely to experience it, and there are several potential causes, including muscle imbalance, issues with the eye muscles or nerves, or issues with the brain’s capacity to regulate eye movement.
  • Exotropia: Exotropia is a sort of squint in which the eye rotates away from the nose and outward. Adults are more likely to have it, and it may be continuous or sporadic.
  • Hypertropia: When one eye is higher than the other, a squint like this develops. A muscular imbalance or other issues with the eye muscles or nerves may be to blame.
  • Hypotropia: When one eye is lower than the other, a squint like this develops. A muscular imbalance or other issues with the eye muscles or nerves may be to blame.
  • Alternating strabismus: The eyes shift back and forth between this form of squint and the normal alignment. It could be brought on by issues with the eye muscles, nerves, or the brain’s capacity to control eye movement.
  • Pseudo strabismus: The form of the eyes or face causes this type of squint, which gives the appearance of misalignment. It more frequently affects young children and is not treatable.

Squinting can cause vision issues and harm a child’s ability to develop normal eyesight if it is not corrected.

Squint surgery is defined as:

Surgery to treat strabismus, sometimes referred to as “squint surgery,” involves realigning the eyes. Although it can be done on adults, squint surgery is typically done on youngsters. In order to realign the eyes, the treatment entails manipulating the muscles that control eye movement. Depending on the precise reason for the misalignment and the unique requirements of the patient, a certain type of surgery may be performed.


There are a number of different squint surgery types, including:



  • Recession: During this surgery, the muscles that direct eye movement are moved farther back on the eye. The eye can be made to turn in or out by doing this to help correct hyperactive muscles.
  • Resection: In this technique, a small portion of the muscles that regulate eye movement are removed. This can be done to repair muscles that aren’t contracting enough and aren’t dragging the eye in the right way.
  • Adjustable suture: In this method, the eye is held in place using sutures (stitching). After the procedure, the suture can be changed to precisely correct the eyes’ alignment.
  • Tenotomy: This treatment includes severing a muscle’s tendon in order to weaken it and free the eye’s movement.
  • Myectomy: In this treatment, a small portion of the muscle is removed in order to weaken it and enable the eye to move in the desired direction.
  • Tenectomy and myectomy: This operation combines surgery on the tendons and muscles to make the muscles weaker and enable the eye to move in the intended direction.



The process is described in general here:


  • Preparation: The patient will need to have a thorough eye exam before surgery to identify the underlying cause of the squint and the best course of action. Before the procedure, the patient might also need to cease taking several drugs.
  • Anaesthesia: Squint surgery is typically performed when the patient is unconscious or under general anaesthesia. The area around the eyes may occasionally be numbed with local anaesthesia.
  • Surgery: The particular technique will depend on the type of squint and the patient’s specific requirements. The eye muscles that control movement may need to be moved, eliminated, or made weaker. It may also require suture (stitching) to retain the eye in the proper place.
  • Recuperation: Following surgery, the patient will need to cover their eye for a few days to preserve it and promote healing. To help with edema reduction and infection prevention, they will also need to take eyedrops. Most people can resume their regular activities within a few days; however, it might take a few weeks for all of the surgery’s effects to become apparent.

To guarantee the best outcome following surgery, it’s critical to closely adhere to the ophthalmologist’s (eye doctor’s) instructions. Squint surgery has the potential to be a very effective treatment for eye misalignment, enhancing vision, easing discomfort from vision, and enhancing the appearance of the eyes.
