The Lasik method is applied for the treatment of visual defects such as myopia, astigmatism and hypermetropia. It is an extremely reliable method that has been used for years. It starts with anesthetizing the eye tissue through anesthetic drops. In this way, the patient does not feel anything during the operation. A valve is then removed from the cornea using an instrument called a microkeratome. This is called corneal flap creation. The corneal flap is folded back and removed from the area where the laser will be applied. Excimer laser beams are sent to the tissue under the removed part. LASIK method is a suitable method for eliminating myopia, astigmatism and hypermetropia problems. The patient does not feel any pain during the application. Improvement in vision begins to give satisfactory results within 3-5 days.
