Ophtec Precizon Presbyopic Toric IOL
Natural Vision at all distances
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
Tolerance of misalignment
In a significant percentage of cases, IOLs tend to rotate a few degrees before they stabilize. This leads to a loss of quality of vision in regular toric IOLs. The TCT optic however is designed to be more forgiving to decentration with less loss of quality of vision
Reducing Glare & Halos
Using segments instead of concentric rings reduces photonic phenomena, allowing patients to adapt more naturally to their new vision
