EXCIMER LASER
Methods of the Excimer Laser
PRK:
This is the oldest method for excimer laser treatment. There is the tissue that is living and extremely thin on the cornea, firstly this tissue is scraped with a scraper called a spatula. The excimer laser is applied after around 9 mm of the corneal surface is epithelialized completely. The eye can be renewed itself after the operation. It has been painful after the operation, and stinging and feeling pain may continue for 3-7 days. The patient's vision clearly takes up to 3-6 weeks.
TPRK:
This treatment can be applied with only Schwind Amaris Excimer Laser Device. And this method is applied without removing epithelium. The healing period is faster than prk method.
Lasik: Lasik Excimer is a surgical method developed for the painless application of laser correction. Lasik method has four main advantages;
1-) It is a more painless method for the patient compared to PRK, and some stinging and pain complaints in the patient on the day of surgery decrease or disappear from the 2nd day.
2-) Improvement of vision is faster. The patient achieves a very satisfactory vision within 3-5 days.
3-) There is no return of the number after the operation or clouding of the cornea.
4-) It can be applied in high numbers up to 10 degrees in myopia.
There are basically 2 steps in the Lasik method;
1-) Corneal Flap Creation
2-) Excimer Laser Application
First Step:
With the LASIK method, the surgeon cut a thin and circular layer before applying an excimer laser. And then this layer is folded back carefully to leave it open to the center of the cornea. The most important subject is how to do flap lifting in this operation. Microkeratome knives are used in the LASIK method.
Second Step:
The excimer laser is applied to the corneal bed after removing the corneal flap and under protection. After that, the flap that folded back in the first step is provided to take the first position.
Who Can Have Excimer Laser Treatment?
In a normal eye without a visual defect, the image falls exactly on the retina, the visual layer where the image is perceived.
Myopia: In myopia, either the corneal surface is very convex or the eye is longer than normal. In these patients, blurred vision occurs in the distance because the image falls in front of the retina layer.
Hypermetropia: The patients have a flatter cornea or a shorter anteroposterior length of the eye, so the image falls behind the retina. In these eyes, the problem of near vision is more than far vision.
Astigmatism: When the eye surface is curved like an egg, both distance and near vision decrease.
SMART LENS
If the patient has cataracts and wants to see both near and far without glasses after cataract surgery, a smart lens is the first choice. The smart lens is placed in the same place in the eye where we removed the person’s natural lens.
There is some visual compromise with these lenses and they are not suitable for everyone. So, every patient needs to have a detailed examination before the surgery. If the patient is suitable for this treatment, permanent clear vision is provided after the surgery.
Things have to be right for this lens to be used.
Anatomically the eye needs to be suitable, which means the surface of the eye needs to be healthy.
If you are found to have dry eye, your doctor may prescribe treatment for this condition prior to proceeding with lens surgery.
Although patients may feel glare around the lights during the adjustment period after smart lens surgery, the glare decreases to a level that is not disturbing within a few months.
