Lasik surgery is the most common refractive procedure used today to reduce a person's dependency on contact lenses or glasses. Refractive errors are caused by an imperfectly shaped cornea, lens or eyeball and the result is a blurry vision. The LASIK procedure utilizes an excimer laser to permanently change the shape of the cornea. After the surgery, the cornea will work to properly focus light into the eye and onto the retina.
LASIK surgery can be performed on people who have nearsightedness, farsightedness or astigmatism. The procedure will take no more than 10 minuter per eye and the patient remains awake the whole time. The surgeon will give you a mild oral sedative and also apply numbing eye drops to your eyes. A device will be placed under your eyelids to hold them back. The surgeon will create the cornea flap using either a microkeratome or a femtosecond laser. After reshaping, the flap is put back in place. Most patients only feel mild discomfort following the procedure. Your vision might improve immediately or over the following days or even weeks. Make sure you follow your surgeon's instructions and you will be able return to work and to your normal activities within a few days!
