Front Step for Laser

As a result, the degree of suitability for surgery is determined and the appropriate laser method is recommended.
 

Laser Treatment Methods

FemtoLasik

This method is the method of corneal layer on the upper surface of the flap under the name of the formation of a thin flap and corneal tissue surface under the cover of the excimer laser is applied to correct the degree of eye correction. This method is performed by topical anesthesia (drop anesthesia) without needle and suture process. The patient does not feel any pain during and after the operation.
 

Femtosecond Lasik

It is the name given to the process of forming the valve with the help of intralase (femtosecond laser). Femtosecond is one of the most important stages of laser surgery. The advantages of this method are that the flap intended for treatment is to be formed at the desired area and quality without blades and the risks at the stage of obtaining the flap are minimal.
 

Femtosecond Wavefront Laser

Femtosecond wavefront laser method, Femtosecond Lasik method is applied to the person (wavefront technique) is applied.
Wavefront Tekniği (Personalized Laser Technology)
It is a laser treatment method which is performed by measuring the results obtained with the wavefront analysis devices and transferring the results to the excimer laser device without touching. Femtosecond wavefront laser method is the combination of today's most up-to-date laser technology and personalized therapy wavefront technology.
 

No Touch PRK

It is a method of number correction by applying laser to the area formed after removal of the epithelial tissue which is the membrane tissue at the top of the cornea layer.
 

PTK (Treatment of Corneal Stain / Irregularities)

Corneal stains may occur as a result of some diseases or eye injuries. In this case, in order to remove these stains, the eye is applied with the technique called PTK. The stains must be superficial to make PTK possible. When the stains are in the deeper layers of the cornea, PTK is not applicable, corneal transplantation is required.
 

PTK can be used for 

  • Eye injuries
  • Corneal infections (corneal germ)
  • Hereditary corneal diseases called dystrophy
  • Repetitive epithelial erosion syndrome (corneal injury once opened, then spontaneous opening)
  • Corneal stain in the eye after pterygium surgery
  • Corneal surface irregularities
