Ophtec Precizon Presbyopic IOL 570 A1
Designed for the correction of presbyopia.
Precizon Presbyopic is a hybrid, acrylic IOL with a Continuous Transitional Focus optic.
Continuous Transitional Focus (CTF)
A CTF optic has an anterior surface with multiple segments for far and near vision.
This transition offers a constant defocus between the two sharp focal points, delivering excellent intermediate vision.
Natural vision at all distances
Transitional zones of the CTF optic offers a full range of vision from near to infinity with a smooth continuous transition.
The CTF aspheric surface forms a broad beam of light, a zone with an enhanced depth of focus, with uninterrupted high quality images for the brain to translate into clear vision at all distances.
Reducing glare & halos
Misalignment tolerance and the use of segments instead of concentric rings reduce photic phenomena thereby helping patients to adapt more naturally to their new vision.
Distribution of the zones is such that in different pupil apertures, under different lighting conditions, the patient can always benefit from the same light distribution for near and far vision.
In cases of tilt or misalignment, the patient can still benefit from the same near and far vision as the segmented zones allow an equal and steady light distribution
