A complete eye test will be done before the surgery to make sure that your eyes are healthy. Some additional tests also will be done to measure the curvature of the cornea, the size of the pupils in light and dark, the eyes' refractive error, and the thickness of the cornea. This will make sure that the corneal tissue is left after the surgery.
You may have burning, itching, or a feeling that something is in the eye. This feeling doesn't last for more than 6 hours in most cases. An eye shield or patch will be placed over the eye to protect the flap. It will also prevent rubbing or pressure on the eye until it has had enough time to heal. It is very important not to rub the eye after LASIK, so that the flap does not dislodge or move. For the first 6 hours, keep the eye closed.The doctor may prescribe mild pain medicine and a sedative. Vision is often blurry or hazy on the day of surgery, and blurriness will improve by the next day. After the surgery, initially doctor will examine your eye and test your vision, and thenthe eye shield will be removed.
When Lasik was first done, a special automated knife was used to cut the flap. Now a common and safer method is, to use a different type of laser to create the corneal flap. The amount of tissue the laser will remove is calculated ahead of time. Once the reshaping is done, the surgeon replaces and secures the flap. No stitches are needed. The cornea will naturally hold the flap in place.
