What is the primary purpose of tarsorrhaphy procedures?

The primary purpose of tarsorrhaphy procedures is to close the eyelids and protect the cornea. This surgical technique is typically utilized in patients who have difficulty closing their eyelids completely due to various conditions, such as trauma, paralysis, or severe dry eye syndromes. By suturing the eyelids together partially or completely, tarsorrhaphy creates a protective barrier for the cornea, reducing exposure and potential damage from environmental factors like wind and dust. It also helps to conserve moisture on the surface of the eye, decreasing the risk of corneal ulceration and promoting healing.

In contrast, relieving intraocular pressure, improving tear production, or correcting lens distortion focuses on other aspects of ocular health and function, making them unrelated to the explicit protective goals of tarsorrhaphy.
