Excimer Laser is a laser instrument that uses argon fluoride gas at 193nm wavelengths, creates ultraviolet lights and controls the beams according to the correction that needs to be done on the cornea through a sophisticated computer system.
Light produced reshape the cornea by dissolving carbon ligaments between molecules of the corneal fiber and removes the corneal texture as needed. It helps lights entering the eye focusing on the retina to correct faulty refraction.

It is generally described as Refractive Surgery that treats refractive errors such as Myopia, Hypermetropia, and Astigmatism. The purpose here is to create a clear vision without the aid of eye-glasses or contact lenses. This is done by reshaping the transparent layer of the eye called “cornea”.

Who can it be Performed on?

The patient generally needs to be over the age of 18. The eye and the retina need to be examined thoroughly. Cornea thickness and cornea topographies (maps) are examined thoroughly and suitability is evaluated.

How is it Performed?

Fiber at a certain thickness (a flap) is lifted from the cornea with a special electric-knife called Microkeratome and refraction is corrected by applying excimer laser on the remaining cornea. This is a surgery that lasts for a few seconds. Once this is completed, lifted flap is placed back.
The laser procedure is completed. There is no need to cover the patient´s eye after this procedure
Complaints that can be experienced in the first few hours;

• Watering
• Redness
• Stinging and burning

These are only temporary. You will feel better the next day. This is the most common surgery in our country as well as the world.


It is a surgical method that corrects refractive errors called abberations occurring at layers other than the cornea with light beams entering the eye. This method is preferred for not causing dispersion or shadowing effect around the light especially on patients who have difficulty seeing at night or who have large pupils. However, it is not suitable for every patient. Suitability is evaluated before the surgery with an instrument called abberometer and the patient is deemed suitable if there is high degree of aberration.
Because Wavefront Maps are person-specific, there are no custom-made treatments specific to each patient


Lasik surgery is completed within 10-15 minutes and is a method that helps you see without the need of eye-glasses or contact lenses for life. There are important factors playing on the success of this surgery that seems simple. The laser technology used during this surgery is one of the most important of these factors. For the laser beams created by the instrument to result in the desired correction, calibration of the instrument, performing regular optical corrections, storing the instrument in the room temperature, and a humidity rate of under 40% are needed. Excimer Laser instrument we use is approved by the FDA and is one of the most-developed and most-high-tech 4th generation lasers. We also have an eye-tracker system that quickly follows the eye during the surgery. Also, the knife and all other tools used during the Laser application need to be single-usage tools.


Bausch&LombZyoptix : A fourth generation zyoptix217 instrument is used that offers the first personalized vision-correction integrated technology in the world. It is a custom lasik treatment that bases Diagnostic Workstation together with Zyoptix wave front aberrometre instrument and corneal topography instrument. Currently, no other instruments can perform back camera elevation measurements. It offers treatment planning abilities aside from specifications above. It helps determine the best for that eye. It has developed the first iris scanning and diagnostics in the world. 100,000 customized ablation treatments were performed across the world with the Technolos217 instrument. It is also FDA approved for customized myopia, hypermetropy and astigmatism.

Allegrotto-Wavelight : It is a German-patented laser along with Excimer laser instrument which contains advanced 4th generation technological characteristics. It performs the correction with a 0.95 mm diameter flying spot laser cluster. It corrects at a high speed of 200-400 Hz. It also has eye-tracker (tracking the eye during the surgery) ability. This ability helps eye movements during surgery not affect the procedure. It is approved by the FDA.

Visx Stars4 : It is an FDA-approved, U.S. patented, 4th generation excimer laser instrument that has reached the highest technology with STARS4IR. It has the ability to change diameters of light beams between 650 microns and 6.5 mms. This ability helps the creation of a flat surface on the cornea and shortens the treatment. It causes less textural ablations- which in turn causes less thinning on the cornea. It has active eye-tracker and iris recognition systems. It is approved by the FDA.

Examinations and Observations

• Detailed eye examination – vision levels with / without glasses – determination of eye glass numbers. Biyomicroscopic observations – Eye-pressure measurement- Retina Observation
• Corneal topography (Corneal scanning with 3 different instruments)
• A system that measures vision problems
• Pacimetry (measurement of corneal thickness )
• Pupillometry (Measurement of the pupil in the light and in the dark)
• Measurement with the Aberometer
• Additional examination with an enlargened pupil


Necessary examinations are completed after the initial meeting with the person who is interested in laser treatment. The treatment takes place on the second day, and a follow-up is scheduled for the third day.

• The person is told not to wear lenses before the surgery for one week-if using soft contact lenses, and two weeks- if using hard contact lenses
• The eyes are anaesthetized with drops for the surgery, covered, wiped, and cables are used to prevent the eye from closing. As a result, you will not be able to close your eyes during the surgery.
• You will be informed about laser rays and will be told where to look. The patient´s eye will be locked on this light; as a result, even if your eye moves, the treatment will not be affected.
• This is the end of the surgery
• Surgery is about 5 minutes per eye.
• You can go home without covering your eyes
• Next day you will need to come back for a follow-up
• You will need to use eye drops for about ten days
• You should not swim for about 20 days.
• Eye make-up should not be done for about 15 days.
• You can shower or have a bath one day after the surgery; however, you should be careful not to get soap in your eyes or rub them
