The WASCA wavefront analyzer is used to customize your correction. It will correct imperfections in your vision which cannot be corrected by eyeglasses or contacts. Most of the lasers use similiar analyzers to correct your vision.
What's special about WASCA is it has the highest resolution in the laser industry.
For example, the analyzer for zioptic B&L 217z analyzes 78 points on the whole cornea, Visx CustomVue analyzes 240 points in 6mm pupil. The WASCA for the Zeiss laser analyzes 800 points in 7mm pupil.
This instrument gives personal correction by integrating the wavefront diagnosis obtained with the WASCA Analyzer into therapy with the MEL-80. However, it can do much more besides. If treatment planning is to be truly customized, it must take into account not only wavefront data, but all the relevant parameters of each individual patient.
On the basis of the highly accurate wavefront data from the WASCA Analyzer, the CRS-Master II allows the treatment planning required for the correction. Your correction profile including the higher order aberrations is analyzed in 0.4 seconds!
Customized aberration correction demands the utmost precision from the Excimer laser. To guarantee the degree of accuracy required, the CRS-Master II adapts the laser energy to each patient's corneal curvature. Together with the aberration Smart Lens Design of the MEL-80, the extremely accurate ablation creates an optimum basis for the correction of even the smallest irregular refractive errors.
In the development of the CRS-Master II, prime importance was attached not only to the optimization of therapy, but also to safety. During all phases of treatment planning, the residual corneal thickness is monitored.
In the treatment planning process, all relevant parameters are displayed on a clearly structured interface. To permit fast, convenient treatment planning in everyday clinical use, the CRS-Master II offers practical, meaningful presets.
The CRS-Master II is truly customized therapy meeting the needs of your personalized correction with precision.
Not all wavefront analyzers used for different lasers are the same although they use the same Shack-Hartman wavefront analysis method, which is the gold standard for true wavefront analysis. The number of points analyzed varies for different lasers. The more points analyzed the more precise is the creation of the correction profile. Zyoptix treatment by Bausch & Lomb uses the ZyWave Aberrometer machine which analyzes 78 points on the entire cornea as compared to WASCA wavefront analyzer analyzing 800 points in a 7MM papillary area of the cornea.
