Know All About Custom LASIK

Know All About Custom LASIK What is LASIK? Custom LASIK can be simply defined as; it is the technique of changing the shape of the cornea by using Laser. Custom LASIK restores your distance vision by correcting your astigmatism, short-sightedness and long-sightedness. It can be achieved by using a cool Excimer laser to reshape your cornea. It does not produce any type of heat nor penetrate the corneal surface. Custom LASIK uses advanced wave front technology to evaluate unique characteristics of your eyes. The characteristics of each person’s eyes are different. Hence Custom LASIK uses detailed information and reshapes your eye during the vision correction procedure by using Excimer laser. Custom LASIK procedure is much more effective than conventional LASIK. While doing the routine eye checkup, your doctor will check your sight by changing various lenses and ask you that if you are able to see the letters from the eye chart clearly. It’s really hard to choose the correct lens from all among them as they look quite similar. In Custom LASIK, the power of lenses is measured in 0.01D units which are required to correct your vision. Hence, it is very easy to get the accurate lenses for your eyes by using the Custom LASIK technique. A computer chooses the lens which most accurately corrects your visionvery instantly, instead of making yourself decide the correct one. For Custom LASIK, the much greater precision of measurements are taken which are gathered from various reference points on the front surface of the eye. To create a detailed map of the refractive error and focusing imperfection, the data have to be gathered called as higher-order aberrations for the entire cornea. Custom LASIK is used to program the laser to deliver a 100 percent personalized vision correction. Custom LASIK are classified into three different types given below.    Wave front-guided LASIK Wave front-optimized LASIK Topography-guided LASIK Wave front-guided LASIK: For your eyes anatomy and vision correction, the laser treatment is completely personalized. Wave front-guided LASIK reduces irregular higher order aberrations which reduces visual clarity to correct nearsightedness, astigmatism and farsightedness. Wave front-optimized LASIK: To preserve the natural aspheric shape of your cornea, the wave front-optimized LASIK uses detailed measurements of the curvature of the front surface of your eye. It reduces the risk of higher-order aberrations called spherical aberration. Some other types of laser vision correction procedures causes spherical
