Lasik surgery involved reshaping the cornea by the use of laser beam to allow the light, which enters into the eye to be correctly focused onto the eye retina for clear vision. It is a pain-free procedure in most cases which takes at least 15 minutes for the two eyes and whose results can be seen as soon as 24 hours after the procedure. This article will keep you abreast with the procedures undertaken before during and after the surgery.
Before surgery
Before the procedure is done the surgeon will examine your eyes thoroughly through what is called an eye exam, this is to ensure that your eyes are healthy enough to sustain the procedure.
In this examination, he or she will look for the shape of the cornea, its thickness, the pupil size when in dim light to determine the diameter of the operation zone, the errors in which you have come to be corrected, and any other eye condition that you may have.
He or she will also evaluate the moisture level of your eyes to avoid dry eyes after the operation. He will also measure the curvature of the front part of your eyes and create your corneas map.
He or she will in addition to that, carry out your wavelength analysis which sends waves through your eyes using wavelength technology which is intended to provide an analysis of the aberrations affecting your vision.

During the surgery
Your surgeon will create a thin and circular piece of the eye cornea using a surgical tool referred to as the microkeratome or sometimes a femtosecond laser.
The surgeon will after that fold back the hanging flap piece of the cornea for it to reach the underlying cornea, he will then remove some of the cornea tissue by the use of an excimer laser.
The laser has the cool ultraviolet beam of light, which removes the tiny amounts of the cornea tissue, therefore, reshaping it according to the defect the eyes have. The laser flattens the cornea for the farsighted eyes while in case of the shortsighted ones the laser makes the cornea steeper
For the people with astigmatism, the laser smoothens the irregular cornea into more of a symmetrical shape. Many people think that excimer lasers cannot correct astigmatism, which is a complete myth.
After the laser has reshaped the cornea, the cornea flap is then laid back to its original place thus covering the area in which it was removed. The eye can then be left to heal on its own.
Because the lasik surgery is in most cases painless, you will only need to use anesthetic drops, making it a very good operation, which does not require bandages or stitches.
