Precizon Presbyopic is a hybrid, acrylic IOL with a CTF (Continuous Transitional Focus) optic designed for the correction of presbyopia. 

What makes this lens unique? CTF (Continuous Transitional Focus) optic

A CTF optic is an optic with an anterior surface with multiple segments for far and near. A smooth transition from far to near is achieved between the segments. This transition offers a constant defocus between the two sharp focal points, delivering excellent intermediate vision.
