Even in ancient times, the Greeks and the Romans noticed that the glass bowl filled with water, has the ability to increase the items. Such balls were first magnifying glasses for people with low vision. Also, before the points, as the devices improve eyesight, used separate pieces of polished crystals or glass. The first points were little resemblance to modern. They were simply round lens in the frame. Inventors long time could not find a way to mount points around the eyes. Appeared lorgnettes, monocles, lenses which were attached even to the hat. Almost five years it took to put the lens in the frame on the nose with arches. But at all times, people do not just want to correct the anomalies of view, and to get rid of the problem, "I see the bad."
Today, there are more than 20 methods for correcting myopia, hyperopia, astigmatism. But the most effective and safest of them ophthalmologists around the world recognize it excimer laser vision correction.
When the laser correction effect is one of the refractive optical media of the eye — the cornea. Its shape is changed, and thereby, the image begins to focus on the retina, as it should be. The high level of security and improvement of excimer laser systems have made the correction procedure simple and accessible to almost everyone. But, of course, do not forget that like any method, laser surgery has some limitations. For example, doctors had for a long time refuse to carry out laser treatment for patients with thin corneas. Now, thanks to the installation of a new generation and a new method of excimerlaser correction — Femto-LASIK, which is available in the Moscow Eye Clinic "Excimer", it became possible solution to this problem.
A unique feature of the femto LASIK is that, unlike other techniques Laser correction, corneal flap is formed by a laser beam (femtosecond laser keratome), rather than a mechanical microkeratome as in the case with other methods. No mechanical action increases the safety of laser treatment for several times and reduces the risk of Acquired postoperative corneal astigmatism, but also allows for laser surgery in patients with thin corneas.
In the process of excimer laser correction procedure Femto-LASIK using a vacuum is a very short period of time, which, of course, is a huge advantage — the patient almost time the entire correction procedure preserves the visual functions and is not afraid "darkness before the eyes" vision restored as soon as possible.
Femtosecond laser FS200 WaveLight, used during the laser treatment method Femto-LASIK, allows professionals to create thin corneal flap by applying a very fast pulses of laser radiation. It has the highest rate of formation of the flap — of 6 seconds! While other models as lasers standard form flap 20 seconds. Correction of outpatient performed using local anesthesia dropping. The preparatory period before the laser treatment takes about 10-20 minutes, and the correction itself 10-15. Femtosecond laser FS200 WaveLight merged into a single system with an excimer laser Allegretto, and so the time of the procedure excimer laser correction, using the two laser systems — minimum.
Combining speed with the capabilities of individual settings WaveLight FS200 Femtosecond laser provides precision of laser correction procedure Femto-LASIK, taking into account the individual characteristics of each patient.
Methods Femto-LASIK — a new word in excimer laser correction of nearsightedness, farsightedness, astigmatism, now available in the clinic, "Excimer".
