Laser eye correction

Laser or LASIK correction is a term for the corneal or keratoplasty of laser technology. The process began in 1970 in the form of a process known as corneal scoliosis, a process by which puncture or puncture occurs in more than one area Or a part of the corneal layer, in the hope of a change in the shape of the cornea to become more regular, which contributes to correct defects and problems of vision, and the results of this process is inaccurate, but in 1980 there was an evolution and technological breakthrough is important, Laser, where they are used accurately and calculated to correct problems and drawbacks Visualization, such as sight length, short sightedness, and astigmatism. This method encountered many obstacles and difficulties at first, but it was eventually approved as an approved technique for correcting vision defects by the US Food and Drug Administration.

Laser vision correction mechanism

The idea of correcting the eyesight is based on the use of a specific type of laser, known as the laser excimer, where it is placed and focused on the cornea layer of the person to correct the defects of vision, and this is done accurately to modify the shape of the cornea, where it reaches a situation that breaks the laser beam on the corneal network directly, Which makes the person see things natural vision without the need to wear glasses, Lasik corrects visual defects ranging from the problem of myopia, in which the fall of the image and located in the front of the retina layer, and the length of the image in which the fall of the image in the back of the layer Retina, and others Stigmatism, which means that the corneal layer of the eye to reflect the laser beam penetrated by a different force, which in turn causes the presence of many images on the retina layer.

Conditions of laser vision correction

A person must be at least 18 years of age and preferably 21 years of age.
The person’s eyesight is fixed during the last two years of the operation, and this is done by following his glasses and measuring his look during the last two years.
Freeness of the eye and its layers of germs and infections.
Women should not be pregnant or breastfeeding.
The tests of the person are intact, specifically the corneal fingerprint or corneal image.

Duration of laser vision correction

This process takes from one quarter of an hour to only one-third of an hour for both eyes, but the time may be longer if the garage is new and beginner in this area.

Laser vision correction results

The results of the operation can not be judged from the first day. The person who underwent the operation will experience some confusion and difficulty in vision during the first hours of the operation. This will end within forty-eight hours. Note that the results of the process appear in some individuals after thirty or ninety days.
