Abstract

Dry eye is one of the most common complications following laser-assisted in situ keratomileusis (LASIK), with nearly all patients experiencing some degree of postoperative dry eye symptoms. Postoperative dry eye affects approximately 50% of patients at 1 week postoperatively, 40% at 1 month, and 20%-40% at 6 months postoperatively. LASIK can cause intracorneal nerve damage, goblet cell damage caused by suction, and can cause changes in the shape of the central cornea. Dry eye diagnosis can be made using a questionnaire to determine the patient's history, examination of tear break up time, staining of the eye surface using fluorescein or lissamine green, and Schirmer's test.
