It is the most common treatment method used in the treatment of Hyperopia, Myopia and Astigmatism.
Lasik method is the most frequently applied method. In this method, a thin layer is cut on the upper surface of the cornea and lifted in the form of a cover, and the refractive error in the eye (Myopia, Hyperopia, Astigmatism) is corrected by applying Excimer laser to the underlying corneal surface. The incision in the cornea is made with femtosecond laser (ILASIK) or microkeratome. This method is performed with drop anesthesia and is not painful. In this
surgery, no needles or stitches are used.
Apart from the LASIK method, there are also SMILE, PRK, NO TOUCH and LASEK methods.
PRK: By scraping the epithelial layer, which is the uppermost cell membrane of the cornea, without lifting the flap.
It is the application of the laser after its removal.
LASEK: It is the removal of the epithelial layer like a flap with the help of alcohol and spreading it back to its place after applying the laser to the surface underneath.
NO TOUCH: It is applied directly on the cornea without touching the eye. It is an alternative method to PRK.
These three methods cause severe pain, burning, stinging and watering for 2-3 days after the surgery.
To whom is laser treatment applied?
Those who are over 18 years of age and those who have been in the last 1 year. Those whose glasses prescription has not changed more than 0.50 diopters in a year.
Those who are myopic up to -9.0 diopters and those who have hyperopia and astigmatism up to -5.
Those whose corneal thickness is sufficient, those who do not have a systemic disease such as diabetic rheumatism, those whose eyes Those who do not have any other disease (such as keratoconus, cataract glaucoma).
The important thing in excimer laser treatment is to decide whether the eye is suitable for surgery or not in the preoperative examination. That's why pre-operative examinations and tests are important. During the examination, the patient's eye numbers are determined. Corneal thickness is measured, a corneal map is prepared and a comprehensive eye examination is performed. Eye pressure is measured, a tear test is performed, the pupil is dilated and the anterior segment and retinal layer are checked with biomicroscopic examination. If no pathological findings are found as a result of these
examinations, surgery is decided.
