Refractive surgery is the term used to describe surgical procedures that correct common vision problems nearsightedness, farsightedness, astigmatism and presbyopia to reduce your dependence on prescription eyeglasses and or contact lenses.Currently, a laser procedure called LASIK (LAY-sik) is the most popular refractive surgery performed in the United States. But there are other types of refractive surgery including other laser procedures and intraocular lens procedures that might be an even better choice for you, depending on your needs.The articles below will help you learn more about your surgical options so you can better discuss them with your eye doctor if you are interested in elective vision correction surgery.LASIK is a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and or astigmatism. In LASIK, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser. The surgeon folds back the flap, then removes some corneal tissue underneath using an excimer laser. The flap is then laid back in place, covering the area where the corneal tissue was removed.With nearsighted people, the goal of LASIK is to flatten the too steep cornea, with farsighted people, a steeper cornea is desired. LASIK can also correct astigmatism by smoothing an irregular cornea into a more normal shape.If you are considering LASIK eye surgery, your first step is to choose a good LASIK surgeon who can evaluate whether LASIK is right for you. Your LASIK surgeon will examine your eyes to determine their health, what kind of vision correction you need, and how much laser ablation corneal tissue removal is required. The doctor will also ask about any health conditions that may disqualify you altogether for LASIK surgery.LASIK is an outpatient procedure, so you don't have to stay at the surgery center overnight. The LASIK surgeon uses a computer to adjust the laser for your particular prescription. You will be asked to look at a target light for a short time while the laser sends pulses of light to painlessly reshape your cornea. The actual LASIK surgery usually takes less than five minutesLASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.Like other types of refractive surgery, the LASIK procedure reshapes the cornea to enable light entering the eye to be properly focused onto the retina for clearer vision.In most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes. The results -- improved vision without eyeglasses or contact lenses -- can usually be seen in as little as 24 hours.If you're not a good LASIK candidate, a number of other vision correction surgeries are available, such as PRK and LASEK laser eye surgery and phakic IOL surgery. Your eye doctor will determine if one of these procedures is suitable for your condition and, if so, which technique is best.Download Lasik Eye Surgery application NOW ! it's FREE!
