compromise for most of us who manage daily a vision in our world is one where eyeglasses, contact lenses are expensive prescriptions, and frequent visits to the ophthalmologist standard. But as Lasik surgery technology has evolved, and its popularity has increased exponentially, people are increasingly opting for refractive eye surgery as an alternative to glasses and contact lenses. Lasik surgery involves the transformation of the cornea – the thin transparent tissue that covers the iris – or section of color – the eye. The lens of the eye – which is directly behind the iris – breaks or curves – light rays so they are seen by the retina – is located at the back of the eye. The task of the retina, then take these beams and covered with messages that can be understood by the optic nerve to our brain. If you understand this process, so know that when our eyes suffer from problems of refraction, the light is not folded properly on the retina and the brain receives image is blurred. If we wear glasses or contact lenses, the light is closer to the goal or placed directly on the retina. Lasik surgery uses laser technology to reshape the cornea so that light is broken clear. During a Lasik surgery procedure to prevent the patient is usually first given anesthetic eye drops will numb the eye and to minimize discomfort, a speculum that is placed on the upper and lower lids to blink. The eye is then immobilized using a suction ring of the cornea. After the eye is immobilized, an incision in the thin upper layer of the cornea is made, resulting in a very thin flap in the fabric. If the flap is folded, the second layer of the cornea – the stroma revealed -. laser power is then used to show up this part of the cornea again. The resurfacing is based on what specific issues in specific eye can be seen to, information that normally during the preoperative visit is collected. placed after the redesign, the flap on the eye, healing occurs naturally and often very quickly. LASIK is a relatively quick – usually less than 20 minutes to complete for both eyes – and most patients say it is virtually painless, so it may be a little uncomfortable at times. While the vision may be blurred until one day after surgery, most people report a clear vision after that date. Lasik surgery, while popular, is not for everyone. In fact, a preoperative examination is essential to determine if you are a good candidate for LASIK. Lead surgeons seeking Lasik usually at least six months of stability limitation in people – which means that you, your glasses or contact lenses remained the same. In addition, the difficulties of refraction in the appropriate guidelines for the correction Lasik for the best views are successful. The doctor will also ensure that you are healthy.
