Lasik Turkey

Lasik therapy and its stages

The word LASİK is the short and abreviated form for Laser Assisted in tu Keratomileusis. The Lasik is an eye surgery that changes permanently the shape of the cornea (the  transparent cover on the front of the eye). İt is done to improve the vision and to lower the need of using eyeglasses or contact lenses.

For a clear vision, the cornea and the crystalline of the eye have to tilt light rays adequately. This permits the focusing of the images in the retina. Otherwise, the images will become blurry.

This blurriness is called refraction error and it is caused by the difference          between the shape of the cornea and the length of the eye.

The LASİK treatment uses an excimer laser (UV laser) to extract the thin layer of the corneal tissue. This will give the cornea a new shape in a way that the light rays will be focused clearly on the retina. İn brief, the LASİK makes the cornea become thinner.

The LASİK surgery is a surgical and ambulatory procedure that takes 10 to 15 minutes for every eye.

The only anesthesic used is a collyrium (eye drops) that numbs the surface of the eye . The procedure is carried out while the patient is awake, but the physian will probably give the patient a medicine to help him relax. The LASİK surgery can be done for one or both eyes during the same session.

To carry out the procedure, a flap of the corneal tissue is created. Later, this flap comes off so that the excimer laser can reform the underlying corneal tissue. A hinge in the flap prevents it from completely breaking away from the cornea.

The first time That the LASİK surgery was carried out, a special and automated knife was used for cutting the flap. Today, a more common and much more safe method is using a different type of laser to create the corneal flap.

The quantity of tissue that will be withdrew with the laser is calculated beforehand. Once the reforming is carried out, the surgeon replaces the flap and secures it. Withou any need for stitches, the cornea will maintain the flap in its place naturally.
