What Is Lasik
In recent years more and more people are thinking about getting rid of their glasses or contacts, but most of them cringe at the thought of having surgery done on their otherwise healthy eyes. This article is for those of you that are thinking about having a LASIK surgery and finding it hard to find information on the subject. LASIK, with it's time tested technology and precise surgical skill, is one of the safest, most effective eye surgery on the market.
LASIK is the use of a leaser beam to modify and reshape the cornea of you eye, thus improving your vision. But why do you have bad vision in the first place?
Our vision is dependent on one thing, light. Without it our vision will not work at all. Our eyes are built such as that they take the light in our environment, or light rays, on the front of the eyes and refract (bend them) so that they become focused on the inside of the eyes surface (the retina). You can very much compare the procedure to that of an camera.
The light on the retina then produce an image that optic nerve then transfer to your brain. The brain interprets the signals and we view them as images. But why do some of us don't see this image as others do?
The problem lies in that the cornea might be deformed. This means that the light rays being transported to your retinas become corrupted, and the image become malformed. For those of you that experience this problem, LASIK eye surgery might be just the solution.
LASIK stand for Laser-Assisted-In Situ-Keratomileusis and is a surgery method which uses laser to correct vision problems for people that are shortsighted, longsighted and anyone with astigmatism.
Before the use of the Excimer laser mechanical tool is used to create a "flap" of the outer corneal tissue that can be folded out of the way and then be put back in place after the surgery. This flap is created to be able to access the underlying corneal tissue that is to be reshaped.
LASIK and most other laser eye surgery work by focusing a tight beam of light, a laser beam onto the surface, the cornea of the eye. Upon contact with the cornea the laser will then, vaporize a very, very small portion of the surface. With the aid if sophisticated equipment the doctor are able to adjust just how much that will be vaporized according to your vision problem.
Once the laser has finished and the flap has been replaced it start to naturally seal itself to the rest of cornea. You will have to wait a few days for your eyes to heal and accommodate, but once that is done, you will no longer need glasses nor contacts. Compared to other eye surgery the healing time is quite quick and one of it's main advantages.
