Lens Cross Section
A: Steep central base curve on posterior lens surface
Intended to match the average central K reading of the keratoconic eye.
B: Fitting curve designed like soft lens base curve
Helps ensure lens movement and fit.
C: Aspheric central optical section on anterior surface
Helps correct spherical aberration and provide a thinner lenticular flange.
D: Central lens thickness (index of thickness)
Helps manage different levels of corneal irregularity.
E: Front-surface cylinder optics
Corrects astigmatism up to -10.00D.
F: Dual Elliptical Stabilization™
Aids in orientation and rotational stability.
