What does ‘treating without a flap’ mean?
In an IntraLASIK treatment, the surgeon creates what is known as a flap. The cornea consists of six thin layers of tissue. When creating a flap, the surgeon uses the laser to loosen three of these layers. The opening is about 20 mm long and has the shape of a horseshoe. The flap is then lifted, like turning a page, so the laser can treat the exposed tissue underneath.
In the Relex SmilePro treatment, a small lens-shaped piece of tissue is created beneath the surface of the cornea using the VisuMax laser. The surgeon then makes a small opening (2–4 mm) in the cornea with the laser to remove this lenticule. This reduces the risk of complications. Because the Relex SmilePro procedure requires only a very small incision, far fewer corneal nerves are disrupted, which significantly reduces the chance of developing dry eyes after the treatment.
