Excimer laser is widely used in the treatment of refractive defects 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 defects 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 image.
Hyperopia: Anterior-posterior diameter of the eye is shorter than normal. Glasses must be used to see clearly.
Excimer laser treatment is divided into different branches according to the method used.
The corneal layer is anesthetized with anesthetic drops. The instrument, called 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 cover 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, alcohol solution in LASEK method and put into place after Excimer Laser. A contact lens is attached to the patient's eye and healing occurs within 2-3 hours. The success rate in the treatment of low numbers is high.
Excimer Laser to who it can be applied?
It can be applied to people over 18 years of age, with myopia up to -10 degrees, hyperopia up to 6 degrees and astigmatism up to 6 degrees and suitable eye structure.
Those with diseases such as glaucoma, keratoconus, diabetes and rheumatism; In addition, Excimer Laser cannot be applied to pregnant women and nursing mothers.
Which treatment are appropriate for the person is determined by examinations and tests. Necessary instructions are given by the doctor.
Hard contact lenses should be discontinued for 3 weeks and soft contact lenses should cease for 1 week.
Burning, watering or blurred vision in the eyes is normal for 3-5 hours after treatment. Eye drops should be used regularly. After 1 day, the patient can return to his / her daily life. Eye makeup should not be applied for 3 weeks and should avoid the pool / sea.
