The LASIK procedure, which has been authorized by the Food and Drug Administration, consists of two stages. In the first step, your eye surgeon creates a corneal flap that is lifted, and the procedure is finished by carefully resealing this flap into place. In the second step of LASIK, the cornea is reshaped using a different laser to correct vision. The corneal flap must not be disturbed for the first week following a LASIK procedure which is why eye protection is advised. It is very secure after 48–72 hours, but if you apply too much pressure in one area as the eyes heal, particularly in the first 72 hours, you could possibly move the flap's edge. To help prevent this issue, we encourage patients to wear eye shields at night. We advise utilizing eye shields while sleeping at night or while taking naps for the first several days following vision correction procedures. Patients should also use extreme caution and avoid rubbing their eyes to avoid putting pressure on the eye and instead use a clean tissue to carefully dab the eye. It is best not to touch your eyes as they heal.
