FEMTO-LASIK - THE MODERN, SAFE AND INDIVIDUAL EYE LASER PROCEDURE

WHAT IS FEMTO-LASIK?

The EuroEyes LASIK method is one of the most modern, safe and individualized procedures to correct nearsightedness, farsightedness or astigmatism. We combine two of the most advanced and precise technologies: wavefront analysis and Femto-LASIK.

Since each eye has very individual characteristics – as unique as a fingerprint – a method is needed that adapts to the eye. With the combination of wavefront analysis and Femto-LASIK, an innovative and revolutionary treatment method is available to you.

The top doctors at EuroEyes, awarded by the magazine FOCUS, thus help you to achieve excellent vision quality. Highly precise and absolutely blade-free!

*The actual costs of a laser eye procedure can only be accurately determined after an extensive preliminary examination – these depend on factors such as visual impairment, thickness of the cornea or the procedure used. EuroEyes can only assess which eye laser procedure is suitable for the patient and what the costs will be after the initial consultation and the findings of the preliminary examination.

HOW DOES FEMTO-LASIK WORK AT EUROEYES?

Cornea analysis

Wavefront analysis creates an individual image of the corneal surface. This analysis is incorporated into the treatment and thus creates a specified correction.

femto-steps-1

Femtosecond laser

The corneal flap is prepared with the femtosecond laser in a way that is gentle on the tissue. The laser treats each eye individually, working with high precision and uniformity.

Excimer Laser

Based on the wavefront analysis data – the fingerprint of the eye – the excimer laser corrects your refractive error and models the cornea.

Rehabilitation

The flap is then folded back again. It adheres again by itself due to internal bonding forces and protects like the body’s own plaster.

ADVANTAGES OF FEMTO-LASIK

Combination of Femto-LASIK and Wavefront Analysis

For the patient it is one of the best possible treatment methods with decisive advantages:

  • The personalized treatment among laser eye surgery methods

  • Consideration of the very specific eye characteristics

  • correction of refractive errors as precisely as is hardly possible with glasses and contact lenses

  • Better visual acuity, better contrast vision and better night vision

  • More safety and higher precision

  • No blade: LASER instead of knife

  • Painless and quick procedure

  • Treatment of higher refractive errors

  • Treatment of low corneal thickness

Revolutionary procedure: improves the quality of vision

During Femto-LASIK with wavefront analysis, all the data obtained is taken into account individually: From the wavefront map, it is possible to deduce exactly in which area of the cornea how much tissue needs to be removed or lasered. In this way, EuroEyes not only corrects your refractive error, but also improves your quality of vision by compensating for your aberrations. EuroEyes-LASIK means customized correction and high quality treatment for you.

INTERESTING FACTS ABOUT FEMTO-LASIK

Femto-LASIK is the further development of classic LASIK and is one of the most precise procedures for the correction of refractive errors.

Why does EuroEyes only use Femto-LASIK instead of microkeratome LASIK?

LASIK (laser in situ keratomileusis) has been a scientifically recognized and established procedure for the correction of refractive errors for many years and is therefore one of the preferred surgical methods of many eye specialists worldwide.
This classic LASIK method has been decisively further developed in recent years: to Femto-LASIK.

In order to correct a refractive error with LASIK, or Femto-LASIK, a small, round corneal flap must first be prepared. The preparation of this corneal flap, also called flap, is done with a micrometer in classic LASIK. In Femto-LASIK, a femtosecond laser prepares the flap – completely without the use of mechanical cutting instruments.

Safety and precision with the femtosecond laser

Femto-LASIK is a precise procedure for creating the corneal flap. Therefore, when choosing a clinic, always make sure that a femtosecond laser is used for laser eye treatment with a flap.

The advantages of Femto-LASIK compared to classic LASIK at a glance:

This speaks for the Femto-LASIK:

  • smooth, even corneal flaps

  • thinner flaps, less tissue removal

  • more precise and safe method

  • painless method, “gentle Lasik”

  • gentle, gentler method

  • faster vision rehabilitation

  • shaped contact lens

  • no miscuts during the surgery

  • no black-out of the eye

  • no interruption of the retinal blood flow

This speaks against the Mikrokeratom LASIK:

  • irregularly shaped corneal flaps

  • more stress on the cornea due to thicker flaps

  • unsafe method, deviations in flap thickness

  • unpleasant to painful

  • increased stress for the eye due to micrometer

  • longer side effects like dry eye

  • suction ring

  • incorrect incisions possible during surgery

  • black-out of the eye

  • interruption of retinal blood flow possible

The femtosecond laser - technical facts

A femto-laser is an infrared light laser that treats tissue such as the cornea not only very precisely, but also with much less heat than other lasers. This proves to be a decisive advantage, especially in eye surgery. The femtosecond laser works on the basis of ultra-short light pulses. These last only fractions of a billionth of a second; their spot size is only 1/100 mm.

VISUMAX-800-faq

The VisuMax femtosecond laser

A specially developed laser system, the VisuMax femtosecond laser from Carl Zeiss, is used for ReLEx treatment. This laser has already proven itself in Femto-LASIK procedures with its sophisticated technology, precision and reliability. Through corresponding further development, it now makes it possible for the first time to prepare a lenticule within the intact cornea with millimeter precision, so that larger incisions and a flap can be dispensed with.

The surrounding corneal tissue is spared as much as possible and the visual defect can be corrected in a targeted manner. A particular advantage of femtosecond technology, in addition to its high precision, is that it is highly reproducible and accurately predictable even when high corrections are involved.

In order to avoid unnecessary compression of the cornea, a contact lens is used that is adapted to the individual corneal anatomy and allows a precisely fitting treatment. This also avoids short-term visual loss, which can be caused by excessive intraocular pressure.

In addition to state-of-the-art laser technology, a functionally sophisticated and ergonomically shaped patient couch has also been developed for ReLEx treatments, allowing for maximum comfort and the most relaxed position possible during the procedure. During the operation, the patient’s position is continuously monitored and can be automatically readjusted if necessary.

WAVEFRONT ANALYSIS - WITH THE "IDESIGN" DIAGNOSTIC DEVICE

Acquiring your very own individual eye profile with “iDesign

With the help of aberrometer/wavefront technology, the individual characteristics of the eye or genetic fingerprint of the eye can be precisely determined. An aberrometer measures the refractive power of the eye – and thus existing irregularities that create aberrations – at several hundred points. EuroEyes uses the latest and most advanced aberrometry technology in this field with the iDesign diagnostic device.

Unlike previous devices, the iDesign Aberrometer measures the refractive power of the eye at a total of 1,250 points. All measured values are recorded graphically. This creates a kind of three-dimensional, personalized map that precisely indicates the refractive power for each point of the eye. Based on this “genetic fingerprint of the eye”, the laser can perform a person-specific, individualized treatment. In this way, the refractive errors of the entire eye are corrected with a degree of precision that is hardly possible with glasses or contact lenses. These aberrations can neither be detected nor corrected with a simple eyeglass lens determination. Since a classic LASIK is based on a spectacle lens determination, additional aberrations cannot be corrected with this treatment method. This is one of the reasons why EuroEyes has not performed this type of treatment for several years.

The “fingerprint of the eye”

Each person’s eye is unique in its structure and refractive power and thus as unique as a genetic fingerprint. Due to the individual nature of the cornea and lens, the human eye does not represent a perfect optical system. In a perfect optical system, for example, the cornea is uniformly and roundly shaped.

In reality, the cornea often has different curvatures at different points and various manifestations of aberrations. Therefore, each eye – even with the same refractive error of, for example, -3.5 Dpt – is individual, unique and different. For this reason, laser eye treatment should be carried out with biometrically personalized data, which individually corrects the total refractive power of each eye as precisely as is hardly possible with glasses or contact lenses.

The advantages of wavefront analysis

The revolutionary procedure improves the quality of vision. In wavefront-assisted femto-LASIK, all data obtained during aberrometry are individually taken into account: From the wavefront map, it is possible to deduce exactly in which area of the cornea how much tissue must be removed or lasered. In this way, EuroEyes not only corrects your refractive error, but also improves your quality of vision by compensating for your aberrations. The use of this revolutionary procedure in combination with the most advanced technology, offers EuroEyes patients the following treatment benefits:
 

  • Better quality of vision

  • Compensation of aberrations

  • Better visual acuity

  • Better contrast vision

  • Better night vision

  • Correction of complicated refractive errors

  • No other method can achieve such customized correction and treatment quality.
