LASIK is the second generation of laser eye surgery. It was developed to overcome many of the drawbacks of the first generation. In LASIK there are two steps to the procedure. The first step is to use a femtosecond laser to create a flap on the surface of the cornea which we then peel open. The second step is to use the Excimer laser to sculpt the surface of the cornea to correct the glasses prescription. We then place the flap back in position on the surface of the cornea and the flap adheres and sticks in place extremely quickly. The visual recovery was extremely rapid after LASIK, typically patients within 12 to 18 hours can see extremely well, also there was only minimal discomfort on some mild watering of the eye and a feeling of a piece of grit in the eye which lasts only a couple of hours following LASIK.
