*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 Sept. 24, 2021. 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?
Vivinex™ combines an active oxygen processing treatment, a square edge design and one of the smoothest and most regular IOL surfaces to provide a low incidence of PCO.1,2,3,4,5,6,7,8

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.
In a randomized multi-center trial and a randomized single-center trial, Vivinex™ demonstrated significantly lower PCO scores versus AcrySof* after 3-years. 1,2
