What is the main purpose of tarsorrhaphy surgery?

The primary purpose of tarsorrhaphy surgery is to protect the cornea, especially in cases where there may be a risk of corneal exposure due to eyelid dysfunction, severe ocular surface disorders, or trauma. By partially or completely sewing the eyelids together, this procedure reduces the exposure of the cornea to the environment, preventing further injury or desiccation. This is particularly beneficial for patients who cannot adequately close their eyelids due to conditions such as facial nerve paralysis or significant burns, which can impair eyelid function.

The procedure acts as a protective measure to maintain corneal health and integrity, allowing for better healing and lowering the chances of complications like corneal ulcers or abrasions. This intervention becomes critical in managing patients with severe eye injuries where safeguarding the cornea is essential for preserving vision and preventing additional damage.
