Tarsorrhaphy is under under local anesthetic as an outpatient procedure. Stitches are placed at the palpebral fissure (corners of the eyelid opening) to narrow it. This reduces exposure to air and increases lubrication of the eye.
Tarsorrhaphy is rarely done as a treatment for dry eye but may be needed in some cases as a temporary treatment (with the stitches later removed). More typical circumstances under which tarsorrhaphy would be done are serious problems with the eyelids preventing full closure, due to paralysis, Bell's palsy, stroke, etc.
