Abstract

Functional and clinical signs of ocular surface involvement are observed after corneal refractive surgery (LASIK or PRK) and are evocative of dry eye syndrome. The surgical process induces a total or partial section or abrasion of the corneal-sensitive nerves. This anatomical consequence of surgery is responsible for a lachrymal dysregulation with reduced tear production. Neither technique is currently able to demonstrate its superiority in preserving the lachrymal secretion. These postoperative findings should be clearly explained to patients before surgery and discomfort should be prevented with artificial tears and/or punctual plugs for 1 to 6 months after surgery.
