In addition to seeing LASIK patients in California, I am also a clinical researcher and Ph.D. candidate in Bioengineering at the University of California, Berkeley in the East Bay. My research concentrates on higher order wavefront aberrations in the human eye and their effect on vision. LASIK has advanced significantly since its FDA approval in the 1990’s. One of the most significant advances came with the adoption of wavefront measuring technology, the wavefront aberrometer. This is a device that measures not only the lower order aberrations, such as near-sightedness, far-sightedness, and astigmatism but also the higher order aberrations. Higher order aberrations are less well-known to the general public but have names like coma, trefoil, and spherical aberrations. These higher order aberrations are problematic for astronomers who have sought to eliminate them while using their telescopes to view distant stars and galaxies. Laser vision correction has advanced partly due to the advanced research by NASA scientists. Patients who are screened for LASIK laser vision correction are measured using a wavefront aberrometer. These measurements are used along with others for determining the most accurate correction that will provide the best possible vision for each patient. LaserVue in California offers the highest level of technology in wavefront LASIK correction.
