Lasik is the most commonly used method in refraction-surgery. This method was used for the first time in 1989 by Dunyagoz Group scientific advisor Prof. Dr. Pallikaris in Greece. At the Dunyagoz Group over 2000 eye treatments are performed each month. Prior to your laser treatment, a thin layer called Flap is made on your cornea with the help of a device called Microceratom. Microceratom is a mechanical knife. It comprises of an arm catching the eye and a knife part cutting by rotating above this arm. Preparing Flap is the previous stage before excimer laser application in Lasik method. The patient will feel no pain during this procedure. Your laser treatment takes 4 or 5 minutes for each eye and you do not feel any pain. During the treatment, you should feel relaxed and abide by the instructions of your ophthalmologist. Upon the completion of your treatment, you leave the laser room without a bandage covering your eyes and are taken to the waiting room for a final control by your ophthalmologist before leaving the hospital. At the  Dunyagoz Group keratome knives are disposable and for 1 time personal use only.
