*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.

†These optimized constants for the calculation of intraocular lens power published by IOLCon on their website: https://iolcon. org are calculated from 1,475 clinical results for Vivinex™ model XY1/XC1 as of September 24, 2021. These constants are based on actual surgical data and are provided by IOLCon as a starting point for individual constant optimizations. The information available on the website is based on data originating from other users and not by HOYA Surgical Optics (“HSO”). HSO therefore does not warrant the correctness, completeness and currentness of the contents on the said website.

Glistening-free clarity

In vitro glistening formation at 14x magnification2

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).3

What features of an IOL limit PCO?

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.1-8

What is the quality of Vivinex lenses?

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). Pérez-Merino P, Marcos S. Effect of intraocular lens decentration on image quality tested in a custom model eye.

Which lens is better Hoya or Alcon?

The Hoya IOL had a significantly lower rate of glistening occurrence throughout the 3 years postoperatively (0.14 ± 0.26) compared to the Alcon IOL (1.79 ± 1.43; p < 0.0001).
