*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 2,857 and 2,884 clinical results for Vivinex™ Models XC1/XY1 and XC1-SP/XY1-SP as of June 10, 2024. These constants are based on actual surgical data and are provided by IOLCon as a starting point for individual constant optimizations.

What features of an IOL limit PCO?

Hoya Surgical Optics iSert IOL

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.1-6

In a randomized multi-center trial, Vivinex™ demonstrated significantly lower objective and subjective PCO scores compared with AcrySof® IQ after 3 years.1

In a randomized single-center trial, Vivinex™ demonstrated significantly lower objective and subjective PCO scores compared with AcrySof® IQ after 3 years.2

These results confirm low occurrence of PCO in both IOL groups and significantly lower PCO incidence with Vivinex™ compared to AcrySof® IQ.
