Laser eye surgery; It is considered the most reliable and effective method to correct refractive errors such as myopia, hyperopia and astigmatism. However, each eye structure is unique, like a fingerprint, and not every method can be applied to everyone.
What is Laser Eye Surgery and to whom is it applied?
It is the process of reshaping the corneal layer using excimer laser technology. Eligibility criteria: Being over 18 years old, eye number not having changed in the last year, corneal thickness being appropriate, not having active eye disease, not being pregnant or breastfeeding.
What is LASIK Eye Surgery?
It is the most widely used method around the world. A thin valve is removed from the cornea and a laser is applied to the tissue underneath, and the valve is closed in place when the procedure is completed. The patient begins to see clearly the next day and does not feel pain. It is the most comfortable method.
What is No Touch Laser?
It is done without any device contact with the eyes. It is based on the principle of stripping the corneal surface (epithelial tissue) only with laser beams and correcting the number with the laser. Since there is no incision or valve, it can be applied safely to patients with thin corneas.
What is PRK Laser?
It is the first generation method of laser surgery. It is the process of scraping the membrane on the cornea manually or with alcohol. It is the ancestor of the No Touch technique. The recovery process is a little longer than LASIK, but it is still one of the gold standards for thin corneas.
Healing Process After No Touch and PRK
Stinging, watering and light sensitivity are normal for the first 2-3 days. Visual clarity usually begins to improve within 3-4 days and full recovery may take several weeks. With LASIK, clear vision is achieved the next day.
Frequently Asked Questions
Is laser eye surgery permanent?
Yes, corneal shaping is permanent. However, after the age of 40, age-related near vision problems (presbyopia) may develop.
Which laser method is better?
There is no single best method; The method that best suits the patient's corneal thickness and eye structure is the 'best' method. The doctor makes a decision after a detailed examination.
Is laser eye surgery painful?
No. The eye is numbed with anesthetic drops. No pain is felt during the procedure. There may be slight stinging in the first days after No Touch and PRK.
