LASIK treatment is the correction of refractive errors such as myopia, hypermetropia and astigmatism with Excimer laser. This method is known to the public as “laser” treatment.

Myopia  means that a person cannot see clearly at a distance while those with hypermetropia. cannot see clearly at a close distance. Astigmatism, on the other hand, is to have distorted and fragmented vision because the light encountering the eye is dispersed to more than one point in the retina.

Astigmatism can be caused by the cornea (the transparent layer in front of the colored part of the eye) or the natural lens inside the eye.

The aim of laser eye is to treat refractive errors such as myopia, hypermetropia and astigmatism by reshaping the cornea tissue with a laser.


Am I Eligible for LASIK?

Persons who are over the age of 18 and whose refractive error has not changed within the last 1 year are candidates for this treatment and whether they are suitable for laser treatment, in other words LASIK surgery can be determined with a detailed eye examination.

The eye laser examination focusses on the thickness, curvature and biomechanical strength of the corneal tissue to which the procedure will be applied are evaluated and other conditions which can prevent the procedure such as keratoconus (a progressive disease where the cornea, which is the transparent layer in the front of the eye, bulges forward and thins), cataracts and severe eye dryness.

In addition, the eyes are evaluated for squinting (strabismus) and possible retinal detachment and holes with a detailed retinal examination. Retinal specialists should evaluate the patient in case detachments and / or holes are encountered in the retina.

Nowadays, refractive defects below approximately 10 degrees in myopia, 6 degrees in astigmatism and 6 degrees in hypermetropia are treated with LASIK.


LASIK Application at our Center

LASIK surgery is performed in the Sapphire clinic center with Excimer Laser and Femtosecond Laser devices for the treatment of astigmatism, myopia and hypermetropia.

Our doctors, who are specialists in lasers and intraocular lens, perform your surgery in our center.

Your suitability for laser surgery and which laser type is chosen is determined after your doctor’s detailed examination.

Detailed information


Who are not candidates for LASIK?

  • Those with a structural defect in the cornea (keratoconus, corneal dystrophy, which means that the cornea is genetically cloudy, etc.),
  • Those whose corneal thickness is not enough for surgery,
  • Those with severe dry eye disease or,
  • Eye pressure (glaucoma)
  • Are not suitable for LASIK.


Furthermore, LASIK is not applied to patients with uncontrolled diabetes, rheumatic disease, connective tissue diseases, HIV-positive patients and pregnant and lactating women (since the effects of hormones on the cornea are known).


Before LASIK Surgery

It is recommended that patients who use soft contact lenses stop using their lenses 1 week before and those who use rigid lenses stop using them 2 weeks before the LASIK examination and surgery. The patient must inform the doctor about any complaints such as burring and stinging in the eyes before the planned surgery.


What should be done on the day of LASIK surgery?

Female patients should not wear make-up on the day of LASIK surgery.

The patient does not need to fast before  the operation since it is performed under topical anesthesia (with anesthesizing drops). A light meal can be consumed.


The Steps of LASIK Surgery

The patient does not feel pain or discomfort during laser eye surgery, however contact is felt and pressure can be felt for a short time during the procedure. The surgery is performed on both eyes in the same session. The steps of the procedure are as follows:

The eyes are anesthetized with an anesthetic drop.

The eyelids and area around the eyes are disinfected and covered with a sticky, sterile drape. Even though this cover partially covers the face, it does not prevent breathing.

The eyelids are opened with a tool to keep them open during the surgery.

A thin valve (flap) is removed from the cornea with an automatic instrument (microkeratoma). In this step, the environment will appear dark for a short time, as the instrument applies vacuum to the eye.

The corneal tissue under the valve is reshaped by applying the laser.

The valve is closed back to the laser-shaped corneal surface and the surgery is completed.

An antibiotic drop is instilled into the eyes. The tool that keeps the eyelids open is removed.

The operation takes 10-15 minutes in total for both eyes.


LASIK After LASIK Surgery

Discomfort such as burning, stinging, watering, blurred vision, pain in the eyes will occur for 3-4 hours after the operation. Protective glasses are used on the day of surgery. Eye drops and tear drops with antibiotics, cortisone will be used according to the physician’s recommendations.

Routine checks are carried out on the 1st day, 1st month and 3rd month after surgery, however their frequency and duration can change as deemed appropriate by the doctor.


Problems That Can Be Encountered After LASIK Surgery

Necessity for a prescription: This can be encountered at varying rates depending on the degree of the refractive error. The doctor will inform you about this before surgery.

Blood blistering in the eyes: This can be observed in the eyes depending on the vacuum applied during the operation, it passes by itself in about 1 month. It does not cause pain.

Diffuse lamellar keratitis: It is an allergic reaction. It is treated by increasing the frequency of use of drops used in treatment or by rinsing the eyes with serum.

Dry eyes: Dry eyes can be encountered for a while after surgery, but this can be resolved with tear drops used in treatment.

Ectasia: This can develop when  a laser is applied to eyes whose corneal thickness and topography are not suitable. However, it can also be encountered corneas with sufficient thickness and structure after laser surgery, albeit rarely.

Cataract surgery can be performed in case the patient develops cataracts at an advanced age after LASIK surgery. LASIK surgery does not prevent any necessary future eye surgery.


Things to Consider After Eye Laser Treatment

Do not rub your eyes or take a bath for the first 24 hours after surgery.

You can return to your normal life after the first 24 hours.

Have your checks done as often as recommended by your physician.


How is Improvement achieved in Astigmatism and Myopia Treatment after laser?

The aim of LASIK treatment is to correct astigmatism and myopia completely.

Prescription values below 0.50 after LASIK surgery are interpreted as successful and the patient does not need to wear glasses.

Patients with high myopia and astigmatism values might still need prescriptions. Your doctor can be more specific about this.


How is Improvement achieved in hypermetropia Treatment after laser?

The aim of LASIK treatment is to correct hypermetropia below 6 degrees. Values below 0.50 after surgery are interpreted as successful and the patient does not need to wear glasses.

The success rate in the treatment of hypermetropia is slightly less than for myopia and astigmatism. Therefore, there is a chance that a prescription will still be needed or that it becomes necessary at a later time. Your doctor can inform you about this.
