There are two steps in the LASIK procedure approved by the Food and Drug Administration. Dr. Tersigni uses a femtosecond laser to make a corneal flap in the that gets lifted in the initial stage and the process is completed by gently resealing this flap into place. A second laser is used in the second stage of LASIK to reshape the cornea in order to correct vision. For the first week, it’s crucial that the corneal flap not be disturbed. After 48-72 hours it is very secure, but if you press too hard on the eye in any one way, especially during the first 72 hours, you could perhaps move the flap’s edge. We advise patients to wear eye protection at night to help avoid this problem. For the first few nights after your LASIK surgery, we advise using eye shields while you sleep at night or take naps. Additionally, patients should be very cautious when dabbing their eyes and avoid applying pressure to the eye by using a clean tissue.
