LASIK
Warsaw · Krakow · Vienna · Zurich
LASIK (Laser-Assisted in situ Keratomileusis – laser ablation within corneal tissue) is a type of refractive laser eye surgery. Unlike PRK/ASA (Advanced Surface Ablation), which is photorefractive keratectomy, LASIK surgery does not require the removal of the epithelium, which means the patient experiences no pain and the eyes heal faster.
An innovative treatment method that effectively corrects vision defects
What is LASIK?
If both eyes are to be operated on during the same procedure, LASIK is the most appropriate method.
The invention of the LASIK method is attributed to Ioannis Pallikaris. In this method, a corneal flap is created using a microkeratome, and the correction itself is performed with an excimer laser.
LASIK at SwissLaser – in brief
LASIK is a flap-based method: the surgeon lifts a thin flap, the excimer laser reshapes the underlying tissue, and the flap is repositioned. At SwissLaser, we create the flap exclusively with the SCHWIND ATOS femtosecond laser – this is FemtoLASIK, without a microkeratome and without a blade. We do not perform classic LASIK with a mechanical microkeratome.
- Range of defects: myopia from -0.5 to -10 D, hyperopia from +0.5 to +4 D, astigmatism up to 6 D – approximate, the examination decides
- Price: FemtoLASIK 11,000 PLN for both eyes, Wavefront variant 12,800 PLN; qualification examination 400 PLN
- Comfortable vision: 24–48 hours, follow-up the next day
- Medical leave: usually 1–2 days, office work after 48 hours
- Warranty: up to 5 years

Variations of the LASIK Method
In the LASIK method with a microkeratome (scalpel) – the traditional method – an incision in the cornea is made using a micro-precision blade. An ultrathin flap is carefully lifted, and then the inner part of the cornea is treated with an excimer laser and reshaped so that the focal point is optimally positioned on the retina. Afterwards, the flap is repositioned, and the cornea heals within a few days.

Variations of the LASIK Method
FEMTO-LASIK (All-Laser-LASIK)
In the traditional LASIK laser treatment method, the cornea is cut with a scalpel (microkeratome), which carries certain risks. In the modern FEMTO-LASIK method, the cornea is opened with a high-precision femtosecond laser.
SBK-LASIK
In the traditional method, the lifted corneal flap has a thickness of 130 to 180 microns – in the SBK-LASIK method, it is only 100 microns. This is an advantage of the special Carriazo-Pendular microkeratome head. Thanks to such precise manipulation of the cornea, individuals who were previously not eligible for laser vision correction due to a thin cornea, high myopia, or a combination of both, can now benefit from the SBK-LASIK method.
EPI-LASIK
In this variation of the method, the surgeon uses an epikeratome – a tool that allows laser correction on the very surface of the cornea, without interfering with deeper layers. Unlike the traditional LASIK method, the epithelial flap is not cut here, thereby minimizing trauma to the corneal stroma. EPI-LASIK is therefore recommended for individuals whose lifestyle may involve an increased risk of eye injury – athletes, soldiers, police officers, etc. This method is safe for patients with corneas that are too thin, which would disqualify them from other laser methods.
Procedure Course
In the LASIK method with a microkeratome (scalpel), an incision in the cornea is made using a micro-precision blade. An ultrathin flap is carefully lifted, and then the inner part of the cornea is treated with an excimer laser and reshaped so that the focal point is optimally positioned on the retina. Afterwards, the flap is repositioned, and the cornea heals within a few days.
The mechanical LASIK method, where the flap is formed with a scalpel, is increasingly less common due to safety concerns. The more modern Femto-LASIK, which involves an incision made by a laser rather than a blade, is already standard practice at our clinic.
Preparation
Before starting the procedure, we thoroughly disinfect the patient’s facial area. Then, we administer anesthetic eye drops to the patient, and the eyelids are held open with a speculum. During the procedure, we ask the patient to look at a flashing light.
Scalpel Incision
In the first phase of the procedure, the surgeon makes an incision in the cornea using a micro-precision scalpel, creating a thin flap approximately 0.1 mm thick. At this stage, the patient may feel pressure on the eye and experience momentary darkness.
Excimer Laser Correction
The previously exposed cornea is reshaped using a computer-controlled laser in a few seconds. This is painless – the patient may only hear the sound of the laser and detect a characteristic odor. The surgeon performing the procedure monitors the laser’s use through a microscope at all times.
Procedure Completion
In the final phase of the procedure, the previously created corneal flap is repositioned. To protect the surgical area, the surgeon places specialized contact lenses with high oxygen permeability on the patient’s eyes. These are removed the day after the procedure.

Indications and Recommendations
LASIK Laser Vision Correction
LASIK is most effective for myopia, hyperopia, and astigmatism.
The most common range of corrected defects:
- myopia from -0.5 to -10 diopters,
- hyperopia from +0.5 to +4.0 diopters,
- astigmatism up to 6.0 cylinders.
The given range is approximate; the decision regarding the feasibility and safety of the procedure is always made by the doctor based on a detailed medical history and precise preliminary examinations.
Contraindications for Laser Eye Surgery
- unstable vision defect – age above 18 or 21 years depending on the clinic,
- eye diseases (glaucoma, cataracts, retinal detachment, corneal scars and spots, keratoconus, pathological changes of the fundus, eye inflammation, and others)
- metabolic diseases (e.g., diabetes),
- allergies and atopy,
- rheumatic diseases,
- autoimmune diseases with significant weakening of the body,
- infections,
- pregnancy.
Complications after Laser Vision Correction
The risk of complications after laser vision correction is estimated at approximately 2%. The more modern the method, the lower the risk of their occurrence. The most common complications include:
- light sensitivity.
- reduced visual acuity with optimal defect correction,
- dry eye syndrome,
- halo effect (mainly at night; wearing anti-reflective glasses for driving is recommended in such cases),
- corneal inflammation,

Recovery Day by Day
- Day of procedure: rest with eyes closed, drops according to schedule, sunglasses outdoors; do not rub your eyes
- Next day: check-up at the clinic – most patients already see clearly and can drive with the doctor’s approval
- 48 hours: return to office and computer work
- One week: light exercise; eye makeup and swimming pool only after doctor’s approval
- Several weeks: contact sports – due to the corneal flap, after assessment at check-up; for individuals at risk of eye injury, we recommend a flapless method from the start
Safety and Possible Side Effects – Honestly
The most common side effect is temporary dry eye in the first weeks – the flap cuts some corneal nerves, so we assess the tear film before qualification. Some patients notice nighttime light effects (halos, glare), which usually subside within a few months. A small percentage have residual defects requiring enhancement. The flap is permanently bonded, but with strong trauma it can shift – that’s why we recommend SmartSight or Trans-PRK for combat athletes and uniformed services. Risk depends primarily on the quality of qualification.
Frequently Asked Questions (FAQ)
What is LASIK laser vision correction?
LASIK (Laser-Assisted in situ Keratomileusis) is a procedure in which a thin flap is created on the cornea, and then the interior of the cornea is reshaped with an excimer laser so that the focal point is optimally positioned on the retina. Unlike surface methods such as PRK, the epithelium is not removed, so the patient experiences no pain and the eyes heal faster. The cornea regenerates within a few days.
Is classic LASIK with a microkeratome still used?
The mechanical variant of LASIK, in which the flap is formed with a blade (microkeratome), is increasingly rare for safety reasons. At SwissLaser, the standard is the more modern FemtoLASIK method, in which the incision is made with a femtosecond laser, not a knife. This translates to greater precision and lower risk of complications.
What range of vision defects does the LASIK method correct?
The LASIK method is best suited for myopia from -0.5 to -10 diopters, hyperopia from +0.5 to +4.0 diopters, and astigmatism up to 6.0 cylinders. The stated range is approximate – the decision on the feasibility and safety of the procedure is always made by the doctor based on a detailed history and precise preliminary examinations.
What are the contraindications for LASIK surgery?
The main contraindications include: unstable vision defect, eye diseases (including glaucoma, cataracts, keratoconus, retinal detachment), metabolic diseases such as diabetes, rheumatic and autoimmune disorders, allergy and atopy, infections, and pregnancy. That’s why every procedure is preceded by a thorough qualification examination, which allows for safe selection of the correction method.
What complications can occur after LASIK surgery?
The risk of complications after laser vision correction is estimated at around 2%, and the more modern the method, the lower it is. The most common include light sensitivity, dry eye syndrome, temporarily reduced visual acuity, and halo effect, mainly at night. In the case of halo effect when driving, anti-reflective glasses are recommended.
How much does LASIK surgery cost at SwissLaser?
Since FemtoLASIK is the standard procedure at SwissLaser, the price from the official price list applies: PLN 11,000 for both eyes (PLN 6,500 for one eye). The qualification examination costs PLN 400, and laser packages are covered by a warranty of up to 5 years. Payment in installments through Santander Consumer Bank is possible.
What is the difference between LASIK and FemtoLASIK?
The difference concerns the method of creating the corneal flap. In classic LASIK, it is created by a mechanical microkeratome (blade), in FemtoLASIK – by a femtosecond laser, with micrometer precision and without blade contact with the eye. The correction itself with the excimer laser proceeds the same way. At SwissLaser, we perform only FemtoLASIK.
How long does LASIK surgery take and does it hurt?
Approximately 15 minutes for both eyes. The eye is anesthetized with drops – you feel touch and pressure, not pain. The excimer laser works for several tens of seconds per eye.
When can I return to work after LASIK?
After FemtoLASIK, most patients return to office work after 48 hours; comfortable vision appears within 24–48 hours, often as early as the next day at the check-up.
Is LASIK safe for people who play sports?
For sports without risk of eye impact – yes, after healing. For contact sports, martial arts, and in uniformed services, the corneal flap is a weak point, so we recommend flapless methods: SmartSight, SmartSight Nova, or Trans-PRK.
Does NFZ reimburse LASIK and are installments available?
NFZ does not finance laser vision correction. The cost of FemtoLASIK (11,000 PLN for both eyes) can be paid in installments through Santander Consumer Bank – we complete the application at the clinic.
Can the defect return after LASIK?
The effect is permanent, because we perform the procedure only when the defect has been stable for 12 months. Changes over the years result from eye aging (presbyopia after age 45), and residual defects can be corrected – procedures are covered by a warranty of up to 5 years.

For the curious: LASIK (laser-assisted in situ keratomileusis) is a procedure with a corneal flap: after it is lifted, an excimer laser reshapes the stroma, and the flap is returned to its place. The flap is created with a mechanical microkeratome (classic LASIK) or a femtosecond laser (FemtoLASIK). ICD-10 indications: H52.0–H52.2; contraindications include thin cornea, keratoconus, and irregular topography.
