Laser vision correction

The world is reflected in our eyes. Because we perceive about 80% of all our experiences through the eyes, our world could be more attractive if we did not need to wear glasses or contact lenses.

This wish can easily become reality.

During refractive surgery, a laser beam shapes the surface of the cornea in a matter of several seconds so that the image appears on the retina. Even though the cornea is remodeled by just a fraction of a millimeter, this modification is enough to restore perfect visual acuity.


Centre de la Vision has purchased the fastest, most cutting-edge laser: Amaris 750S, produced by a German company called Schwind.


With its remarkable speed of operation and a pulse rate of 750 Hz, the Amaris 750S laser allows our ophthalmologists to make a correction of 1 diopter in 1.5 seconds. Extremely high precision is achieved thanks to its unique eye tracking system.

Amaris 750S is the only such device that enables laser correction without removing the epithelium of the cornea. The entire procedure is contact-free and uses nothing more than the laser beam.



The patient reports at the Center on an arranged date. A full qualification costs 250 zł and takes 1.5-2 hours. During the examination, the physician will administer pupil dilating drops; for this reason, you are advised not to drive for the visit.

You should not wear contact lenses for a specific period before the qualification:

  • soft lenses – 2 weeks before
  • toric lenses – 3 weeks before
  • rigid lenses – 4 weeks before

  • Examination of the anterior and posterior part of the eye with a slit lamp
  • Ostrość wzroku z najlepszą możliwą korekcją
  • Visual acuity and the greatest achievable correction
  • Tonometry (measurement of intraocular pressure)
  • Pachymetry (measurement of corneal thickness)
  • Topography of the cornea (map of the cornea)
  • Biometry (measurement of the length of the eye)
  • Keratoconus screening

The Sirius diagnostic station operates in conjunction with the AMARIS 750S laser, and results of the qualifying examination are automatically transferred into the memory of the laser to allow high-precision correction of vision.


  • myopia from -0.5 Dsph do –10.0 Dsph
  • hyperopia from +0.75 Dsph to +6.0 Dsph
  • astigmatism up to 6.0 Dcyl


  • unstable refraction (it should not have changed for a year)
  • age below 21 years
  • diabetes
  • glaucoma, cataract
  • pregnancy, breast-feeding
  • keratoconus, corneal scars, cornea too thin
  • retinal detachment
  • inflammation of the eye
  • allergy
  • artificial pacemaker
  • menstruation
  • herpes simplex


  • You report for treatment at an arranged date.
  • You put on a disposable gown in a changing room. A nurse cleans your face with a disinfectant and applies drops to the eyes.
  • You enter the operating room, where eye drops are applied again.
  • The surgeon prepares the operating area by applying an ophthalmological drape with a fenestration for the eye and a speculum that prevents blinking.
  • The surgeon positions the arm of the laser over your eye and begins the surgery, which lasts from 7 to 20 minutes for both eyes.
  • After the surgery, you take a rest of about 30 minutes in a resting room; after that, the surgeon performs a control examination of your eyes using a slit lamp. You are then given the necessary recommendations and discharged from the clinic.


PRK (photorefractive keratectomy)

This technique does not create a corneal flap, thus reducing risk of complications. During the surgery, the surgeon removes the surface layer of the cornea and performs precise photoablation using an excimer laser. This changes the curvature of the cornea and as a result, increases optical power of the eye. After the treatment, you will be asked to wear a contact lens for a few days to allow the outer layer of the cornea to heal. Visual acuity improves gradually after a PRK treatment, and the correct level is reached usually after about 3-6 weeks. The PRK technique is used in treatment of myopia down to -7.0 Dpt, hyperopia up to 4.0 Dpt, and astigmatism.

TransPRK (Trans-epithelial photorefractive keratectomy)

This technique, developed by German company Schwind eye-tech-solutions, uses an excimer laser to remove the corneal epithelium with the aid of unique ablation algorithms that take into account the fact that the thickness of the cornea decreases away from its center. The treatment is conducted using the ‘non touch’ method.

Advantages of TransPRK:

1. The surgery is a one-stage process that uses a laser and which does not require touching the eye with any kind of a tool. For these reasons, removing the epithelium is safer, and the risk of stromal dehydration is lower.

2. The epithelium is removed in a smaller area than in other techniques, allowing for quicker healing.

3. This type of surgery can be performed on patients with irregularities of the stroma.
LASEK (laser subephithelial keratomileusis)

LASEK (laser subephithelial keratomileusis)

In LASEK, a solution of alcohol is applied to the cornea. This allows the outer layer of corneal epithelium to be folded back in the form of an extremely thin flab (60-90 µm thick). LASEK is used in treatment of myopia down to -7.0 Dpt and hyperopia up to +6.0 Dpt both with and without astigmatism.

PTK (phototherapeutic keratectomy) 

This method uses photoablation performed with an excimer laser to treat corneal conditions, that is, recurrent corneal erosion, corneal scars, dystrophy and degeneration, keratitis and deep inflammation after removal of pterygium, and inflammation after removal of a foreign body. The method is also used to shape the surface of the cornea after previous refractory treatment.
