LASIK is the abbreviated form of Laser assisted in situkeratomileusis. LASIK is the most performed refractive surgery method nowadays. The technique was initiated by the Spanish ophthalmologist Barraquer along with microkeratome and keratomileusis works and developed later by the Russian scientist Fyodorov in 1970s. Keratomileusis is called the technique in which a thin layer of cover is lifted within the cornea. The cover is called a flap. Flap is created via a microkeratome ( a vibrating micro knife) or femtosecond laser. The cornea below the flapp is reshaped with excimer laser. LASIK is a safe surgical technique performed over 8 million people in the world from 1990s.
The procedure lasts 2-4 minutes and the healing process is fast. Myopia, hypermetropia and astigmatism can be corrected. Patients go back to their work and normal life 1 day after the surgery without staying at the hospital overnight.
For preparation a patient wears bonnets and overshoes, the eyes are anesthetised with a drop, eyelids and eyelashes are sterilised with Batticone. He/she lays down to the surgical bed with the eyes covered with a sterile drape and an ecartor put on the procedure eye to keep it open. The laser device settings and patients data are checked just before the operation. A corneal flap is created via microkeratome or femtosecond laser, the patient is told to look at the green light inside the device, the eyetracker follows the eye movements and the laser procedure begins. The flap is closed after the operation and an immediate postoperative biomicroscopic control is made. The patient wears safety glasses and prescribed postoperative drops and booked for the fist day control 1 day after. He/she is told to not rub the eyes and that he/she wil experience stinging, pain and light sensitivity for a couple of hours.
