SMILE


SMILE or Small Incision Lenticule Extraction is the latest laser eye surgery procedure. With LASIK, a flap is created within the cornea in order to expose the area requiring laser treatment. This flap may cause damage to the corneal nerves resulting dry eye for some patients. LASIK requires a number of steps, The first step is the creation of the flap. The second step involves actual laser treatment. The final step involves repositioning the flap. With the SMILE procedure, there is no need to create a flap. A special femto-laser creates a thin disc of tissue within the intact cornea. The amount of tissue corresponds to the optical correction required to reinstate clear vision. The thin disc of tissue is then removed through a tiny opening in the cornea. As the laser is designed to by-pass the corneal nerves, dry eye is significantly reduced following the SMILE procedure. Another advantage of SMILE treatment is the speed of the procedure. This is because treatment occurs on one single device. The SMILE procedure is suitable for shortsighted people; those who may have been advised against other laser treatments because of a thin cornea, or people who have dry eyes with contact lenses.
