HOYA Vivinex™ Toric

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
