During the first step of the LASIK procedure, a corneal flap is created to allow treatment and correction on the corneal surface. In traditional LASIK, this flap was created with a surgical blade. IntraLase FS technology allows our experienced surgeons to create the corneal flap with a laser rather than a blade. The IntraLase FS helps surgeons control the shape of the corneal flap, customizing it to your individual vision correction needs and allowing for a larger range of treatment. In fact, with this technology, patients who were previously not candidates for traditional.
In the second step of the LASIK process, an excimer laser is used to reshape your cornea and correct your vision. All-laser LASIK improves the accuracy of this step by precisely pinpointing both higher order and lower order vision imperfections (known as aberrations).
Lower order aberrations: Nearsightedness, farsightedness and astigmatism. Before advanced LASIK procedures became available, only these types of imperfections could be corrected by LASIK. Now, higher order aberrations can be detected and corrected as well. Higher order aberrations are best defined as a series of imperfections within the eye's optical system (for example the ocular lens), which are unaccounted for in traditional LASIK treatments. Higher order aberrations most often affect your vision at night, and cause halos, starbursts or glare to be visible around bright objects such as car headlights
The ALLEGRETTO WAVE is the first vision correction system to receive concurrent approval for the treatment of both nearsightedness and farsightedness. Due to the laser's unique wavefront-optimized ablation algorithm, the system delivers superior clinical results and a maximum level of safety for our patients.
