Femtosecond Laser Vision Correction (Femto-LASIK) in Moscow
Glasses and contact lenses help you see clearly, but they aren't always suitable for everyday life. They can interfere with driving, playing sports, working in front of a screen, traveling, or in dry air.
Femtosecond laser vision correction in Moscow helps reduce dependence on optics if the eye structure allows for the procedure to be performed safely.
We begin with a diagnosis. The doctor evaluates refraction, the cornea, the tear film, the retina, and the optic nerve. Only then can we determine whether laser vision correction is suitable for the patient and what results are reasonable to expect.

What is femtosecond laser vision correction?
Femtolasik is a method that reshapes the cornea. The cornea helps focus light, so precise correction helps direct light rays to the retina more accurately. This method is part of refractive surgery and is performed after a complete eye assessment.
Femtolasik is a two-stage procedure. First, a corneal flap is created, then an excimer laser performs the optical correction. The flap is then replaced; sutures are usually not required.
How a Femtosecond Laser Works
The femtosecond laser creates a corneal flap using pre-calculated parameters. The doctor takes into account:
- Corneal thickness
- Corneal shape
- Treatment zone diameter
- Keratopography data
- Pachymetry and aberrometry
The excimer laser then changes the curvature of the cornea to correct nearsightedness, farsightedness, or astigmatism.
How does this method differ from traditional laser correction?
With traditional LASIK, the flap is created using a mechanical microkeratome. With Femto-LASIK, this step is performed by a laser, allowing the doctor to more precisely determine the depth, diameter, and position of the flap. The choice of method depends not on the name, but on the corneal thickness, refractive stability, ocular surface condition, age, and visual objectives.
The table helps you quickly see the differences between the methods, but it shouldn't be used to choose the procedure yourself. The doctor makes a decision only after an examination: assessing the cornea, refraction, ocular surface condition, and possible limitations.
| Criteria | LASIK | Femto-LASIK | PRK | |
|---|---|---|---|---|
| Flap formation | Mechanical | Laser | No flap created | |
| Postoperative comfort | Usually good | Often higher | In the first few days More discomfort | |
| Early recovery | Fast | Usually fast | Longer | |
| Patient selection | According to indications | According to indications | According to indications | According to indications |
This table is not a substitute for a consultation. Sometimes Femto-LASIK laser vision correction is appropriate, sometimes a superficial technique is safer, and sometimes the doctor recommends avoiding surgery.
Who is the procedure suitable for?
Patients often come for a consultation with a clear goal: to become less dependent on glasses or contact lenses. However, before surgery, it's important to assess medical conditions rather than just desire.
Safe correction requires stable vision, adequate corneal thickness, and the absence of factors that could increase the risk of complications.
Contraindications and limitations
Contraindications to vision correction can be temporary or permanent. Surgery is postponed or not performed:
- In case of unstable refraction
- Signs of keratoconus
- Insufficient corneal thickness
- Active inflammation
- Severe dry eye
- Certain retinal diseases
- Severe healing disorders
Pregnancy and breastfeeding usually require postponing the planned procedure.
Some restrictions are only identified after an examination. Therefore, you should not rely on the experience of others or advertising descriptions of the technology. If the risk outweighs the expected benefit, the doctor will suggest an alternative option for monitoring, treatment, or optical correction.
Main indications: nearsightedness, farsightedness, astigmatism
The main indications for laser correction are related to refractive errors. With nearsightedness, a person has difficulty seeing into the distance, with farsightedness, they strain more often when working close, and with astigmatism, images may be distorted at various distances.
Nearsightedness, farsightedness, and astigmatism can coexist. Therefore, the doctor evaluates not only the diopters but also the cause of the decreased clarity.
When is this method particularly effective?
This method is most often considered in adult patients with stable refraction, sufficient corneal thickness, and realistic expectations. The surgery improves optical conditions. However, it does not treat:
- Retinal diseases
- Optic nerve
- Age-related changes in the lens
For patients seeking vision correction in Moscow, a clear path is especially important: diagnosis, ophthalmic surgeon consultation, method selection, preparation, surgery, and follow-up.
General information
How femtosecond laser vision correction is performed at our clinic
We explain the entire process to patients in advance, from diagnosis to follow-up examination. First, the doctor ensures that the surgery can be performed safely. Then comes preparation, the correction itself, and monitoring during the first few days, when it's important to properly assess healing.
Pre-procedure diagnostics
Before surgery, the doctor checks not only visual acuity using a chart. A comprehensive vision diagnosis is essential:
- Autorefractometry
- Visometry
- Keratotopography
- Pachymetry
- Aberrometry
- Fundus examination
- Evaluation of the anterior segment and tear film
Based on the examination, the ophthalmic surgeon determines whether it is safe to reshape the cornea and whether individual vision correction is appropriate for the patient.
How the correction itself is performed
On the day of surgery, drop anesthesia is administered. There is usually no pain, but the patient may feel pressure, see bright light, and hear the doctor's commands.
First, a femtosecond laser creates a corneal flap. The excimer beam then reshapes the cornea according to a calculated program, after which the ophthalmic surgeon checks the tissue position.
What's important after the procedure
Vision may be unstable during the first few hours. Tearing, light sensitivity, a gritty sensation, a burning sensation, and moderate discomfort are possible. After the surgery, avoid rubbing your eyes, stopping eye drops on your own, visiting a sauna, swimming pool, dusty areas, or intense exercise during the restricted period.
The patient receives a list of symptoms in advance that require immediate contact with the clinic. These include:
- Pain
- Sudden deterioration in vision
- Severe redness
- Purulent discharge
- Severe photophobia
Routine examinations are necessary for the doctor to assess the healing process and the quality of the results.
Frequently Asked Questions
Before scheduling, patients often ask about safety, recovery, and prognosis. We answer these questions before the procedure, because a calm decision begins with clear information.

Sign up for a consultation and diagnostics
Vision correction in Moscow should begin with a consultation and a comprehensive examination. This helps determine whether the surgery will provide the expected benefits and whether there are any risks. We explain the results in simple terms, while maintaining medical accuracy.
When to seek help
You should schedule a consultation if glasses or contact lenses interfere with work, sports, driving, studying, or your normal daily routine. Other reasons may include discomfort from lenses, visual fatigue, or a desire to evaluate the possibility of surgery.
If you experience pain, a sharp decrease in vision, sudden double vision, eye injury, flashes, or a "curtain" in front of your eye, an urgent consultation with an ophthalmologist is necessary.
What is the initial consultation like?
During the initial consultation, the doctor will discuss your complaints, your experience with glasses or contact lenses, past illnesses, medications, and expectations. An examination will then be performed to assess the safety of the procedure. If the method is suitable, we discuss preparation, procedure date, and early visual rehabilitation guidelines.
Femtolaser vision correction in Moscow at our center—from diagnosis to follow-up examinations. We don't promise the same results for all patients, but we do everything medically necessary to ensure a well-founded decision.
