A device that produces ultraviolet light at a wavelength of 193 mm using ArF (Helium + premix) gas. It breaks the chemical bonds between the molecules of the corneal tissue where the light falls, eliminating the tissue without damaging the surrounding tissues. In this way, the deformity that causes the refractive error is corrected, the refraction of the cornea is changed and the person can achieve clear vision without using glasses or contact lenses.
With laser eye surgery; Myopic astigmatism, myopia-astigmatism and hyperopia disorders can be treated. Astigmatism and hyperopia can now be treated using special equipment.
Not everyone can undergo laser eye surgery. It is very important that the structure of the eye is suitable for the laser. First of all, a detailed examination is needed. The glasses that the person sees best are determined and the retina of the eye is examined. The condition of the retina is very important, especially for myopic eyes. Because the risk of tears and holes in the retina of the eye with high myopia is higher than in normal eyes. If there is such a situation, it is treated with Argon laser. After the problem is eliminated, other examinations are continued. The second important research is aimed at determining the properties, structure and thickness of the corneal tissue. If all the data are suitable, surgery is decided. Generally, we can roughly divide those who can or cannot have this laser surgery into groups as follows
Who Can Have Laser Eye Surgery:
* Those who are over 18 years of age.
* Those whose eye degree has not changed more than 0.50 degrees in the last two years
* Those with myopia up to 10 degrees, astigmatism up to 7 degrees, or hyperopia up to 7 degrees (Some authorities still debate these criteria).
* Those with sufficient corneal thickness and solid tissue.
* Soft contact lenses If used, at least 10 days before surgery; If hard contact lenses are used, those who stopped using them 20 days ago.
Who Cannot Have Laser Eye Surgery:
* Those with rheumatic diseases.
* Heart patients.
* Diabetes patients.
* Pregnant or breastfeeding women.
* Those who have had previous eye surgery.
* Keratoconus patients.
* Those with eye tension.
* Those with severe eye problems such as cataracts.
Lazy eye and etc. Vaccination does not prevent laser surgery from being performed. The eye with amblyopia will be able to see as well without glasses and contact lenses after the surgery as it did before the surgery. In other words, laser surgery saves the person from glasses and contact lenses, but it does not cure laziness. People with strabismus are first treated for strabismus, and then their refractive errors are treated. If the amount of misalignment in the eye is not too much and this misalignment is not noticed when the person wears glasses, it is possible to get rid of glasses and misalignment after laser treatment. Laser eye surgery takes approximately 7-8 minutes. The duration of the laser operation is about 25-30 seconds. During the intervention, no pain is felt and local anesthesia is used. There is no need to stay in the hospital after the surgery. After the operation, the person is sent home.
If we talk about the most common problems that can be seen in patients after Excimer Laser, we see that night vision complaints and contrast vision decrease in patients after Lasik are more than other methods, their tendency to dryness increases, and there is a problem in patients over 40 years of age. These are situations in which the need for glasses for close reading may occur again after a while.
