* 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. 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.

Hoya surgical optics Introducing Vivinex ImpressTM. Our enhanced monofocal IOL

Be Impressed by Vivinex ImpressTM

Our enhanced monofocal IOL

Set a new benchmark for visual outcomes achieved by your monofocal patients

Vivinex ImpressTM enhances the intermediate vision of monofocal patients

Vivinex ImpressTM provides greater than 1 line of binocular visual acuity improvement at 66cm

product-image

Vivinex ImpressTM provides the same best-corrected mean distance acuity as a standard monofocal aspheric IOL1

Vivinex Impress™ improves intermediate visual acuity at 66 cm (-1.5 D defocus) by more than 1 line1

Vivinex ImpressTM improves intermediate vision and provides consitant refractive predictability

product-image
  • No difference in best-corrected mean distance visual acuity at 4m between Vivinex ImpressTM and a standard monofocal aspheric IOL1
  • Approximately 1 line improvement in distance- corrected visual acuity at 66cm in the Vivinex ImpressTM group1
  • Refractive predictability was excellent in both Vivinex Impress™ and the standard monofocal aspheric groups1
    • within 0.25D of target: 60% vs 55%
    • within 0.50D of target: 87% vs 77%
    • within 0.75D of target: 100% vs 91%
