Excimer Laser

Excimer laser is widely used in the treatment of refractive errors such as hyperopia, myopia and astigmatism. It is a UV laser with a wavelength of 193nm obtained by electrically stimulating the argon-fluoride gas mixture.

Refractive Errors

Refractive errors are one of the most common eye problems. In a normal eye, external rays break through various layers and reach the visual point on the retina. In some cases, fracture does not occur in a healthy way and vision problems may occur. Low vision, pain and discomfort in the eyes are symptoms of refractive errors.

Myopia: The rays coming from the outside are focused before they reach the visual point. In this case, the patient has to wear glasses to see far.

Astigmatism: Corneal deformity. Causes reflection and blurred vision.

Hyperopia: Anterior-posterior diameter of the eye is shorter than normal. Glasses must be used to see clearly.

Treatment methods

Excimer laser treatment is divided into different branches according to the method used.

LASIK

The corneal layer is anesthetized with anesthetic drops. The instrument, called as a speculum, is placed to prevent the movement of the eyelids. An incision is made to the corneal layer and the lid formed as a result of the incision is removed. Excimer Laser is applied to the underlying corneal tissue. After the application, the incision is closed and the operation is terminated.

PRK – LASEK

The epithelial layer located at the outermost part of the corneal layer is removed and Excimer Laser is applied. This removal is performed with the help of surgical instrument in PRK method and alcohol solution in LASEK method. And epithelial layer is put into place after Excimer Laser. A contact lens is weared by the patient and the eye heals within 2-3 hours. The success rate in the treatment of the patients with low eye prescription is high.
