Squint Correction

Why is squint correction done?

Squint correction is a surgery done to correct the misalignment of eyes due to congenital or acquired conditions. There are many forms of squint such as

• Esotropia or crossed eyes with one eye turned inwards, towards the nose
• Exotropia or wall eye/horizontal deviation with one eye turned outside, towards the temple
• Hypertropia or vertical deviation with one eye turned upward, towards the eyebrow

How is squint correction done?

• The eye is rotated and the conjunctiva cut open to expose the muscle which is either
• weakened by recession of muscles – detaching it from the eye and reattaching it further back on the eye with a suture or
• strengthened by resection – the muscle from the eye is detached, its distal end excised, and then reattached to the eye, with a suture.
• Either process is repeated for each muscle that is operated on.
