Lasik is an acronym and it stands for Laser-Assisted in Situ Keratomileusis. It is one type of refractive laser eye surgery performed on patients suffering from myopia or nearsightedness, hyperopia or farsightedness and astigmatism. Lasik basically removes the need for glasses or contact lenses, which may be quite a hassle for some people. Many patients prefer this over the other type of refractive laser eye surgery, which is the photorefractive keratectomy or PRK because Lasik is relatively less painful and recovery time is quicker for Lasik than for PRK. There are instances, however, when PRK is more suited for the patient than Lasik.
Lasik uses laser beams to reshape the cornea, allowing the person to see better. The cornea is the part of our eyes, the “window,” so to speak that allows light to enter in. When laser beams reshape the cornea, the eye specialist focuses the light on the retina, which is that part at the back of our eyes that is mainly responsible for our sight. This procedure improves vision for people who suffer from mild visual disorders.
At the start of the lasik eye surgery the eye surgeon will cut a tiny piece of tissue from the cornea of the eye. Before this is surgery has been performed, the eye surgery will take vital steps to ensure the patients eye is ready for surgery. The eyes will heal very fast and you’ll be on your way to having clear vision.
The lasik eye surgery will not take very long at all, usually just about an hour or less for both eyes. Their is not a long recovery period or overnight stay on the hospital.
Lasik surgery is a common procedure in the United States and all over the world; millions have said they were quite pleased with the results. Still, the cost, which reach up to several thousand dollars just for on eye, can be prohibitive. The procedure is still relatively new as well so the long-term effects of this seemingly ground-breaking procedure remains to be seen.
