In May 2009, a new laser center that equipped with modern femtosecond and excimer superlasers was introduced by our Clinic. The femtosecond technology introduced new standards for laser eye surgery, presenting the highest level of precision, safety and stability.Femtosecond laser VisuMax:
The VISUMAX system is designed to provide smooth and precise flap cutting capabilities for refractive laser surgery. This technology, combined with MEL 90 excimer laser, delivers excellent clinical outcomes coupled with the potential for a unique optimized workflow for refractive surgeons and improved comfort for their patients. Moreover, VISUMAX is the only laser system in the world that is able to perform FLEx procedure – the latest innovation by Carl Zeiss Meditec that provides new possibilities in laser eye surgery. The VISUMAX was certified by FDA to perform FemtoLASIK in 2007.

What is femtosecond laser?
Femtolasers work in infrared spectrum, and produce ultra short impulses. One femtosecond is 10-15of a second. This type of lasers provides maximal control for the surgeon and maximal comfort for the patient.

Femtosecond lasers are used:In laser eye surgery to prepare a cornea for the laser surgery (corneal flap creation in FemtoLASIK method)
In laser eye surgery to perform the FLEx method
In corneal transplantation surgeries
To implant intracorneal segments
What is FemtoLASIK?
Traditionally, performing classical LASIK surgery, the surgeon prepares cornea for laser eye surgery with a special instrument called microkeratome. The surgeon creates a thin superficial corneal incision and forms a corneal flap. Then excimer laser starts its work and corrects the vision problems. Finally the flap is returned back to its place and the surgery complete.
Using this technique, instead of making an incision with a microkeratome, another laser is used, called femtosecond laser. It is more precise, safe, and provides maximal comfort for the patient.
The femtosecond laser is also used for corneal transplantations, keratoconus treatment and other purposes.
Advantages that patient receives from the new technology:Minimal risk of complications
High precision of laser treatment
Maximal patient satisfaction with results
Method can be applied on thin corneas and higher diopters

FLEx (Femtosecond Lenticule Extraction)
A standard laser eye surgery consists of two main steps: first, the surgeon prepares the corneal surface for the optical correction. It is done either mechanically, using a special instrument called microkeratome or using a laser beam, that creates the necessary surface for the optical correction. Then the laser is applied to correct the refractive error, and the latest technologies, called the FLEx method, allows performing the surgery in only one step. The laser that operates in our Centre is the only laser in the world that combines the power of two lasers in one, so there is no need of any laser combination. It is convenient for the patient, safe, provides quick recovery and perfect results.

Eye diseases treatment
The femtosecond technology is not used only to correct refractive errors, but also in keratoconus treatment and corneal transplantations.

How is the surgery performed?
Doctor disinfects the surface of the eye and applies anaesthetic eye drops. The surgery is completely painless.
Then a special lens is applied and the surgeon prepares the surface using a femtosecond laser. It takes about 30 seconds per eye.
The flap is moved aside and an excimer laser starts its work, changing the refractive power of the cornea. It takes about a minute per eye, and the flap is repositioned.
The surgeon examines the eye, applies eye drops and the surgery is over. Almost immediately after the operation the patient can find his vision significantly improved, although sometimes it takes a few hours for the vision to clear.
Then the patient is asked to sit 30 minutes with his eyes closed. The doctor examines the patient, issues eye drops and arranges a visit for the next day.
