ALSA FIT Fourier
Fourier Optic IOL
ALSAFIT FOURIER is a total presbyopia correcting IOL for cataract and RLE surgery procedures. By carrying a disruptive innovation in optical design, Fourier Optic is fitted out with reverse apodization in all optical zone (6mm) . This unique pattern is developed by transforming classical edged overlapping Fresnel diffraction into Fourier Optic with reverse apodization. Throughout reverse apodized Fourier Optic , it contists of 14 soft transition steps which support possessing high quality of vision at all distances regardless of lighting condition.
