What is Excimer Laser?
​

There are 3 methods for the correction of eye disorders such as myopia, hyperopia and astigmatism: Glasses, Contact Lenses and Excimer Laser. In the past years, sensitive knives were used to create scratches on the transparent part of the eye, called the cornea, to correct these disorders. The term "EYE DRAWING"  is used for this method. Today, eye number correction is done with excimer lasers and no scratches are created on the cornea. It is more correct to use the term "excimer laser" instead of "eye drawing" for the process to get rid of eye numbers.

​

Excimer Lasers have been used in the treatment of eye disorders since 1988. It is the treatment method with the highest patient satisfaction. During the procedure, the refraction of the cornea is changed with micron precision. In myopia, the refraction is reduced, in hyperopia it is increased, in astigmatism, the refraction is equalized on the entire corneal surface. These processes are extremely fast (5-6 seconds).

​

To Whom Can Excimer Laser Eye Surgery (eye drawing) be applied?
​

People who want to have Excimer Laser must meet 3 conditions:

  • be 18 years or older,

  • Stability of the eye number, that is, the eye disorder does not increase more than 0.5 in a year,

  • Appropriate eye structure.

 

Apart from these conditions, Excimer Laser is not recommended for people with diabetes, connective tissue disease, rheumatism, pregnant or breastfeeding women. 

It should not be forgotten that one of the basic rules of medicine is the rule "There is no disease, there is a patient". Each patient is unique and should be evaluated individually. Therefore, it is not the right approach to say that everyone who meets these criteria will have a laser, or those who do not can definitely not have a laser.

​

What are Excimer Laser Eye Surgery (Eye Drawing) Methods?
​

There are 2 different Excimer Laser eye surgeries. These are PRK (Photorefractive Keratectomy) and Femto-LASIK (Laser in-situ Keratomileusis). A comparison is not made in such a way that one of these methods is superior to the other or that one method is better than the other.  Both methods have advantages and disadvantages. There is no difference between the results when the appropriate method is selected for the appropriate patient. There is no feeling of pain or pity during both procedures.

PRK

In this method, the superficial cell layer of the cornea is first removed with a surgical instrument or alcohol. Then the number is reduced by applying the excimer laser process. Then the contact lens is placed. The superficial cell layer is self-renewed in about 3 days and at the end of this period, the contact lens is taken back.  The laser procedure takes about 3 minutes for one eye. 3-5 days after laser treatment. Control examination is carried out between days.

Advantages of PRK:

  • It can be applied to thin corneas.

  • Dryness is lighter and lasts shorter.

  • In the future, corneal tapering is less likely to develop.

  • The cost is lower as a single laser system is used.

Disadvantages of PRK:

  • Sinking, watering and light sensitivity that can last for two days.

  • Complete recovery of vision takes longer time than LASIK.

  • The probability of staining on the cornea at high numbers.
