Modern LASIK Procedures have reached very high levels of accuracy. A new method called iris registration helps to further improve accuracy.
In the wavefront technique a unique map of your laser treatment is created. This map tells the laser how to treat not only nearsightedness and astigmatism but also other errors of focusing such as chromatic aberration and coma called higher order aberrations. These higher order aberrations are not treatable with glasses or contacts. Getting rid of these aberrations gives the patient having wavefront LASIK the opportunity to see better than they have ever seen previously, even with glasses or contacts.
Just like a map of the earth that is referenced to the North Pole, the wave front map must reference to the person and eye being treated. Until now, that reference was the patient’s physical position under the laser. With iris registration, a digital photograph of the detail in the iris, the microscopic ridges and valleys in the colored part of your eye provide alignment information that allows the laser tracking system to “Lock On” further increasing the precision of the LASIK technique.
