Vivinex™ Toric
UNPRECEDENTED CLARITY AND ROTATIONAL STABILITY.
Designed for outstanding optical quality, Vivinex™ Toric has proven rotational stability for precise astigmatism correction and provides patients with an astigmatic cornea with unprecedented clarity of vision. Product quality, dedication and attention to detail are deeply rooted in our Japanese heritage, and with 1 million lenses sold worldwide, surgeons‘ trust in Vivinex™ is proven.
Vivinex™ Toric offers the following benefits:
- Glistening-free hydrophobic acrylic IOL material1,3
- Proprietary aspheric optic design for improved image quality2
- Active oxygen processing treatment and sharp optic edge to reduce PCO3
- Vivinex™ Toric IOL preloaded in the proven VivinexTM iSert® injector system
- Outstanding rotational stability, Median rotation 1.1° [ range: 0.0° – 5.0° ]4
- 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, 1 month and 6 months4
