Lasers for excimer laser vision correction

Amaris 500E Excimer Laser (Schwind, Germany)
Sshwind Amaris 500E Excimer Laser is a state-of-the-art technological innovation in the field of laser vision correction systems. Numerous clinical trials have proved high efficiency and safety of Amaris 500E for improvement of visual acuity and quality of vision in myopia, hyperopia, astigmatism and higher degree aberrations (refraction distortions).

Automatic Fluence Level Adjustment “AFLA” (Automatic Fluence LevelAdjustment) provides optimal correlation between the number of laser pulses and the laser energy delivered to the tissue, resulting in quick ablation with optimal corneal topography alignment. The laser system with a 500 Hz laser pulse repetition rate is efficiently supplemented with a 5D eyetracker which compensates for micro movements of the eye in five dimensions. You will get the best quality of correction, the procedure will be safe, and rehabilitation will be fast.

IntraLase FS60 femtosecond laser (USA)
This femtosecond laser is used to perform excimer laser correction according to a revolutionary femtolaser technique. In femtosecond laser eye correction corneal flap is formed not with a microkeratome but with the help of femtosecond laser beam, i.e. it is absolutely noncontact. IntraLase FS60 femtosecond laser has high frequency and short pulse duration.

Pulse duration is measured in femtoseconds (one trillionth of a second, 10-15 s), which allows to separate corneal layers at molecular level without heat generation and mechanical effect on surrounding eye tissues. The femtosecond laser beams are focused at a preset depth with an accuracy of a few microns to create a layer of “micro-bubbles” of the desired configuration. By positioning multiple micro-bubbles in the neighborhood using a computer-controlled program, the ophthalmic surgeon is able to obtain a plane of separation of absolutely any shape with the highest precision.

The corneal flap formed in the process of femtosupported laser correction is uniform in thickness, thin and has smooth borders. The constant thickness of the corneal flap excludes higher order aberrations due to the effect of inhomogeneous refraction of rays, increasing safe procedure and dramatically reducing rehabilitation period. The ideal smooth surface of the corneal tissue separation border enables to achieve a significant reduction in the rehabilitation period and preserve high contrast sensitivity.

IntraLase FS60 femtosecond laser is a member of the complete line of iLasik system. It works in combination with Amaris 500E excimer laser and WaveScan aberrometer. This complex makes it possible to perform laser vision correction taking into account the smallest peculiarities of a patient’s visual system.
