LASIK is selectable. It is not aesthetics, such as lifting or is medically necessary, such as heart bypasses, but does not solve a physical problem and the quality of life. But if you are comfortable with glasses or contact lenses, do not really have any type of laser eye surgery.
There are a number of reasons why it might be a good candidate for LASIK. Not all the alternatives LASIK at the sameDegree of surgery. For example, intracameral intraocular lenses (ICL), which are pending FDA approval, may be a good option if you are too nearsighted or farsighted to benefit from LASIK. A small lens is located behind the pupil, but only before the eyes "of the existing lens, adding an appliance store additional focus and change the globe-stop. Under this procedure could not believe it has become very popular, but probably not to replace The LASIKadditional risk factors.
There are different types of intraocular lenses (IOL), which can be implanted in the eye, temporarily or permanently correct moderate to severe nearsightedness. In myopic patients, light rays focus in front of the retina, vision blurred, so that will change the IOL behind the cornea is able to concentrate and improve eyesight. Like LASIK, this is an outpatient procedure takes a little 'time.
There are several laser surgeryAlternative methods are available when you are not a good candidate for LASIK. Photorefractive One of the most popular and is the most common keratectomy (PRK), which uses a laser to form the outer surface of the cornea. (LASIK makes changes within the cornea.) Patients with low to moderate myopia and hyperopia, with or without astigmatism, PRK has proven to be extremely useful. This procedure is often recommended if you are not sure of the corneaConditions, such as ulcerated areas, scars, or what is called multiple times the erosion of the cornea. "It takes longer to reach a final result of PRK surgery, because there is a greater amount of tissue that requires healing.
A new procedure called laser epithelial keratomileusis (LASEK) – a simple change in the photorefractive keratectomy (PRK) – was developed by an Italian surgeon and first described in medical literature in 1999. In LASEK, the surgeon loosensthe outer layer of the cornea (epithelium), but unlike PRK, the epithelium is not removed, but folded so that the laser can shape the cornea, is exposed to it. After application of the laser, the surgeon replaces the corneal epithelium. Vision recovery after LASEK is generally faster than with PRK, but slower than LASIK.
LASEK, which is the preferred laser eye surgery is used (a so-called "excimer" laser), not approved by the FDA.Surgeons can not get LASEK, except for volunteers for clinical trials. Initial results with this procedure are promising, but many other studies before LASEK is approved as a safe and effective is necessary.
