LASIK stands for Laser In-situ Keratomileusis, which means “to shape the cornea from within.” During LASIK surgery, this is exactly what happens: your cornea is re-shaped using a state-of-the-art Excimer laser. This improves your eyes’ ability to focus, providing you with clear vision.
To better understand how this works, you must first understand what causes vision problems like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. All of these problems occur when your cornea is not curved like a perfect sphere. A person with 20/20 vision has a spherical cornea, which allows light to converge directly on the retina. If you are nearsighted, your cornea is instead shaped more like an egg or a football – and if you are farsighted, the overall length of your eyeball is too short. These problems cause light to focus improperly in your eye.
Before LASIK is performed, every microscopic irregularity that is affecting your vision will be mapped out using an advanced technology called Wavefront Diagnosis. This “map” of your eyes will then be used to guide the Excimer laser in re-shaping your cornea, helping it target and correct each irregularity. The result is clear, unhindered vision that does not require dependence on glasses or contact lenses.
