Frequently Asked Questions

Is LASIK a safe technique?

LASIK is a surgery approved upon a long-term follow-up by American Ministry of Health (FDA) that is famous for being a strict establishment and acknowledged as safe by all health authorities.

Will LASIK prevent any other future treatment or operation regarding my eyes?


Am I eligible for LASIK or not?

First of all, you have to be subject to a detailed eye examination. The values should be accurately measured in examinations with and without drops. Afterwards, the structure of eye is examined in details by corneal topography and pachymetry.  As a result of these examinations and investigations, your doctor will decide whether you are eligible for laser or not.

What is the success rate in LASIK?

First of all, criterion for success should be described. The purpose is to change the value of the patient's eye with a single intervention into a value that would not require wearing glasses such as 0, 0.25 or 0.50. The success rate is 98% for values less than 8; whereas this rate is 95% for the higher ones. In case regression, re-advancement of the values, occurs the purpose then is zeroing the diopter values again with a single intervention. The success rate in the second treatment is 85% with 2% and 5% odds.

Who can be treated with LASIK?

* People between the ages of 18 and 65 (the young ones should have their diopter values not changed within the last year)

* Myopic people up to 12.0 values

* Hypermetropic people up to +7.0 values

* People with myopic and hypermetropic astigmatism up to 6 values

Who can not be treated with LASIK?

  • In case of a disease causing thinning and deformity in keratoconus (cornea).
  • People with inadequate thickness of corneal tissue
  • People with uncontrolled uveitis
  • People with uncontrolled eye tension (very rare)
  • Cases of severe "dry eye"
  • Pregnant and puerperant women
  • People with problems such as advanced diabetes and kidney diseases

When should one discontinue using contact lenses before the operation?

People with soft lenses should discontinue using 1 week before; whereas the ones using gas-permeable semi-hard lenses should discontinue using them 3 weeks before the operation.

How is the operation performed and what should I do during the operation?

You will be administered a tranquilizer about 45 minutes before the operation.  This smoothes away the excitement for operation and enhances the conformity. Shortly before entering into the laser room your eyes are administered anesthetic drops to ensure that you will not feel any discomfort or pain.  When you lie down on the laser table your eyelids are wiped with an antiseptic solution and covered by a plastic cover. A special wire is used in order to separate your eye lids to ensure that you can not close your eyes even if you want to. Afterwards, you will see the bright light of the microscope and a green punctuate light in the middle of it. The doctor will ask you to stake in that green light during operation. The fact that you are comfortable and at ease will relatively shorten the duration of the operation.

What happens if I move my eye during laser treatment?

Since laser focuses on your eye due to active "eye-tracker" the treatment proceeds uninterruptedly.   

How long does the operation take?

The treatment lasts for 4 minutes for each eye.

What are the do's and don'ts following treatment?

Antibiotic drops are administered in your eye after the operation and pads are put over your eyes to avoid dusts.  You can take them off when you arrive home. Blurred vision is an absolutely natural situation. You may have a feeling of burning, stinging and watering in your eyes for a few hours. Pain is rare; so, it is possible to relieve from it with a simple analgesic in case it occurs. Avoid touching, scratching and rubbing your eyes. Avoid having a bath and washing your face. You should not watch television or read anything. Administer you antibiotic drops as recommended by your doctor. The following morning, you will have to be controlled briefly which is highly significant.

- The drops are to be used for 1 week and then they are discontinued.

- You should avoid rubbing your eyes harshly (especially during the first month).

- Avoid swimming pools and sea for 2 weeks.

- Avoid eye make-up for 1 week.

- You may have a bath or take a shower following the control on the next day of the treatment. However, you should avoid soap and shampoo getting in your eyes.

Will my eye value be zero instantly?

On the next day following the operation, most of the patients acquire a satisfactory visual acuity.  The values may be stabilized within a few weeks. Myopic patients will be slightly hypermetropic the next day. This is a temporary situation which may cause difficulties during reading.

Hypermetropic patients will be myopic the next day. This is also a temporary case. Blurred far vision is possible within the first weeks. The values are expected to be stable in the control that will be performed after 1 month.

When will my controls be performed?

Following the control on the first day; you are required to be controlled on the 1st, 6th and 12th months. Later on, annual controls will be enough.

What are the characteristics of the laser device used in your hospital?

Wave Light - Allegretto Excimer Laser Device (Germany) is the 4th generation excimer laser having superior features.

It executes the correction with flying spot laser beams of a diameter of 0.95mm.
It has a higher speed than the other lasers providing a much more proper treatment level due to its ability to treat fast. Also, it has a special scanning tracker system (eye-tracker) at 250 Hz. The therapy is continuous even if the patient moves his/her eye during the treatment.

Also, it is ensured that the treatment is performed on the proper area due to the characteristics of the eye to turn around the central axis (cyclotorsion) and to adjust the kappa angle (the angle between the eye pupil center and visual axis).

Will I be able go to work the next day?

Although some of our patients go to work the next day, the experts recommend relaxation of 2 or 3 days.

How many people had this operation?

Our team of experts under Dr. Sinan Göker has performed 50 thousand eye operations.  To set global examples, 960 thousand visual improvement operations were performed with laser in the United States and this number reached to 1.5 million eyes in the year 2000.
