If you have poor eyesight and you have worn eyeglasses or contact lenses all your life, then you might want to consider LASIK eye surgery. LASIK is the acronym for Laser-Assisted in Situ Keratomileuses. This is a procedure where the patient has to undergo surgery to reduce or totally eliminate a person's poor eyesight. There are certain eye imperfections that cause poor eyesight. Examples of these are: - Astigmatism A person with astigmatism sees 'distorted' imaged which is a result of deformities or irregularities on the lenses of the eyes. - Nearsightedness A person who is nearsighted has a condition called myopia. Here, the patient experiences difficulties seeing objects at a distance. - Farsightedness On the other hand, a person who is farsighted sees far objects without difficulty but the same does not apply to near objects. This condition is also called hyperopia. To treat these ailments, LASIK eye surgery is used, and this is the most common method of refractive surgery performed for patients nowadays. 'The Procedure' In LASIK surgery, there is a knife-like tool that is mainly used for the procedure: the microkeratome. This is used to produce a very thin and rounded flap in the clear, outer layer covering the front or the eye which is the cornea. A more technologically-advanced way to create this flap is by the use of laser. The shape of the cornea is changed permanently once this surgery is performed. After the flap on one side of the eye is produced, this is folded back to reveal the stroma. The stroma is the mid-section of the cornea. Afterwards, the microkeratome or the laser beam will vaporize a part of the stroma by producing computer-controlled pulses. Then, the flap is put back into place after making the necessary corrections. There are other types of refractive surgery that may be performed on a patient,depending on the degree of visual disability. 'The Pros & Cons' This type of surgery that aims to correct poor vision is very popular. Why do you think this is so? Here is a list of the advantages of LASIK eye surgery: 1. You will not feel pain while undergoing the procedure. 2. The results are immediate. Right after the surgery, you will experience an improvement with your eyesight. At the very least, you will get to literally "see" results a day or two after the operation. Still, there is a downside to this type of medical procedure. Take a look at some of them and decide for yourself if undergoing the surgery is worth the risk: 1. Complications may arise. Different patients respond differently to treatment. If there are certain health issued that your doctor is not aware of, the procedure may not have positive results. 2. There are certain jobs or profession which prohibit an employee undergoing LASIK eye surgery. Be sure to check with your employer first if you think that this surgery might in any way inhibit you from doing your work. 3. The procedure is quite costly. Over the years and because of its gaining popularity, the costs have gone down considerably. However, it is still quite a hefty amount to squeeze out of your pocket if you are on a budget. If you plan to undergo this type of surgery, ask your doctor about the rates. 'Should You Do It?' If you are not the type of person to boldly take risks,LASIK eye surgery may not be right for you.
