You may have heard of LASIK surgery before, and wondered exactly what it really is. LASIK surgery is a type of eye surgery designed to correct vision for people that wear glasses or contact lenses. The acrynym "LASIK" stand for "Laser-Assisted in SItu Keratomileusis". It works by changing the shape of the cornea in order to correct poor vision.
The procedure begins by placing eye drops in your eyes that will make them numb. The eyes are then meticulously cleaned, and your eyelids are affixed to an instrument called a 'lid speculum' to hold them open. The surgeon will then use either a mechanical blade, or a laser to cut a corneal flap, which will be attached only by a flap on one side. During this phase of the procedure, your vision will be somewhat diminished, and you will probably feel some pressure and some minor discomfort.
Next, the corneal flap is pulled to the side, and a laser is used to remove a small amount of corneal tissue, as you stare at a fixed location. it is not uncommon to smell a small amount of burning material at this point, but do not be alarmed. Once the surgeon is finished with the laser, the flap is repositioned, and an eye shield is is placed over your eye so that you do not rub it, or get anything in it until the cornea has had an opportunity to heal.
The surgery has a very high success rate, enabling people with vision problem to leave their glasses and contact lenses behind. The procedure is relatively quick and simple, and patients have little or no pain or discomfort, however, it is important that you understand what the procedure entails, as well as any risks you might incur, before electing to have it done.
First of all, you want to make sure that procedure will be performed by a qualified eye surgeon. Make sure you ask how many LASIK procedures they have performed, and about their qualifications. Your eyes are too important to take these important questions for granted.
Keep in mind that a good eye surgeon will ask many questions of you, to make sure that you are a good candidate for LASIK. Your age is one such criteria, as is the strength of your cornea. Make sure that you disclose your full medical history to endure the risks.
