HOYA Vivinex™ Toric IOL
The glistening-free hydrophobic Vivinex™ Toric IOL offers unprecedented clarity of vision and outstanding rotational stability.
Active oxygen processing treatment
Vivinex™ is made from a novel hydrophobic acrylic, using a proprietary manufacturing process that includes a unique, active oxygen posterior surface treatment
Combined with its square edge design and smooth, regular IOL surface, it has been demonstrated to provide a low incidence of PCO in several studies.
Glistening-free hydrophobic
Vivinex™ is rated glistening-free with 97.0% of lenses demonstrating <10 glistenings per 10mm x 2mm field and showing significantly less glistenings than AcrySof® IQ SN60WF* (p<0.0001).
Outstanding rotational stability
- Median rotation 1.1° [ range: 0.0° – 5.0° ]
- 100% of lenses (n=103) had ≤5° of rotation from their initial axis at end of surgery through all follow up visits at 1 hour, 1 week and 6 months

The A-constant is presented as a starting point for the lens power calculation. When calculating the exact lens power, it is recommended that calculations be performed individually, based on the equipment used and operating surgeon’s own experience.
Optimized Optical constants Source: https://iolcon.org Calculated from 910 clinical results based on caucasian patients for Vivinex™ Model XY1/XC1 as of August 22, 2019.
