Before the lasik procedure you have to undergo eye examination including refraction of your eyes, corneal topography, pachymetry and retinal evaluation, to make sure that you will be a suitable candidate for lasik.

On the day of lasik procedure do not wear eye make up, jewellery, cologne or hair spray. Your vision may be blurry after the procedure, so be sure to bring some one who can drive you back home.

Your eyes will be numbed with anesthetic eye drops so that you will not feel any pain during the procedure. Once everything is prepared, the doctor will place a speculum between upper and lower eye lids to prevent blinking. Then he will use an instrument called microkeratome to make a hinged flap on the surface of cornea. They you will be asked to focus on a red blinking light so that your eye will be well centered and it is time for the computer guided Exlimer laser to accurately reshape the corneal tissue. The laser will only be used for about a minute. Then doctor will carefully put the flap back in place and remove the eye speculum.
