What tests are done during the preoperative visit?
A thorough eye examination is done to decide whether the patient’s eyes are healthy and suitable for laser vision correction. Patients read an eye chart which helps show how well they see with and without glasses. Eye drops will be used to anesthetize the eyes and to dilate the pupils for this examination. Tests are done which determine the shape of the cornea, the thickness of the cornea, the optical defects in the eye and the pressure inside the eyes. These tests are painless. We recommend patients arrange a ride home and bring sunglasses to wear after this visit. The anesthetic drops wear off in 30 minutes and the dilating drops take approximately 3-4 hours to wear off.
