Customized laser treatment
The term stands for “tailor-made” corneal surgery. Because no eye is perfect and no two eyes are alike, the reflected light shows an individual pattern-the so called WAVEFRONT. For an eye, this pattern is as unique as a fingerprint.
These methods detect irregularities in the eye. WAVEFRONT technology can be used with both LASIK and LASEK surgery. The WAVEFRONT laser can correct total aberrations (not only low order aberrations but also high order aberrations of the patient’s specific corneal curvature). This procedure is even more precise than previous technologies, to optimize your vision and avoid night vision side effects (such as halos around lights).
For many patients there are numerous reasons for poor vision. In a single eye, there may be several different types of visual imperfections. These imperfections are classified as lower-order aberrations and higher-order aberrations.
Lower-order aberrations such as nearsightedness, farsightedness, and astigmatism have always been easily diagnosed and treated. They can be corrected with glasses, contacts or traditional conventional Laser eye surgery.
Higher-order aberrations are more complex and cannot be corrected by traditional means such as glasses, contact lenses, or by conventional Laser eye surgery such as LASIK or LASEK. Higher order aberrations can cause such symptoms as glare, reduced contrast, doubling, or reduced vision quality. These affect the quality of vision.
1. High speed spot laser beam
With a repetition rate for 500Hz and a very small spot size of 0.54mm, it provides ideal conditions for highly precise treatments. It also allows for proper treatment of the smallest curvatures of the cornea and results in a very smooth corneal surface.
2. Eye tracker
The ultra fast eye tracker(1,050Hz) follows eye movements within the world’s shortest reaction time of only a few milliseconds. An integrated high speed eye tracker assures that each spot of the treatment is placed in exactly the right spot, even if you move your eye.
3. Aspheric individual curvature treatment
The WAVEFRONT laser also features a new approach to laser vision correction. Most current laser systems may leave the eye with increased spherical aberration, which degrades the quality of vision, and may also cause the glare and halo phenomenon. The Wavelight laser adjusts the treatment based on individual curvature measurements, with the hope of minimizing spherical aberration and improving vision quality both during the day and night.
4. Optimized energy stability control
The WAVEFRONT laser also affords optimized energy stability control. This program automatically balances the energy levels during the treatment to ensure that every laser pulse (of thousands in a treatment) is of the correct strength.
5. Laser treatment zone size
The WAVEFRONT laser also appears to be beneficial in treating patients with large pupils. This is because of the optimized shaping of the periphery of the corneal treatment as well as the larger treatment zone size. It can be used to minimize night glare and halos.
