There is already a different variation of LASIK eye surgery available, and it is called custom LASIK. The main distinction this has over the normal LASIK procedure is the utilization of a wavefront measurement system, hence its other name, wavefront LASIK. This operation uses three-dimensional measurements that would reveal the ways of how the eye processes images. This in turn will be used as a guide by the laser in restructuring the cornea. With this technology, more precise treatment has been made possible, and there are several eye corrections that cannot be treated by traditional LASIK that can now be cured using custom LASIK.
But getting the procedure for you is not that easy. It requires the patient to be qualified according to the guidelines made by the Food and Drug Administration (FDA). This includes careful examination of the eyes. The factors considered are the level of vision defects, the cornea’s thickness, and whether the eyes suffer from myopia, astigmatism or hyperopia. The particular model of the laser system to be used will also be taken under consideration. When all of this has been analyzed, only then can it be determined if the patient is suitable for custom LASIK.
Because of the degree of precision in correcting visual problems, custom LASIK has been widely considered an excellent choice for eye patients. Not only does it solve problems regarding visual sharpness, but it also positively affects the vision quality of the eye. This means that the chances of certain complications happening after LASIK surgery can be reduced with custom LASIK. Getting into to the specifics, the wavefront technology makes it more feasible to treat both lower-order and higher-order aberrations. While lower-order aberrations like astigmatism and nearsightedness can be taken care of through traditional means, the complicated higher-order types can only be treated with custom LASIK. These higher-order aberrations cause things like halos, glares, more difficulty seeing at night, and blurring problems. Custom LASIK surgery treats this difficult niche.
How exactly does custom LASIK work? To start off, LASIK surgeons use the device to send out a ray of light into the eye of the person intended for surgery. The retina will then reflect the light out through the pupil and into the measuring device called the aberrometry. The wave of that light will then be positioned in a specific pattern that assesses aberrations of any order. The result will then be exhibited in a helpful three-dimensional map, and this information will be encoded in the laser performing the surgery. Finally, the surgeon will analyze the data and customize the procedure accordingly.
