MC and LC :  Two Different Lenses, Two Applicatons

Extreme H2O 54 Toric lenses provide significantly improved
vision for more than 75% of the astigmatic population. 

LC - designed for patients with astigmatism from 0.50D to 1.00D

MC - designed for patients with astigmatism from 1.00D to 1.50D 

 

Design and Material

 

Toric Stability is a Function of Design & Material

Extreme H2O 54 Toric lenses are made with our advanced breakthrough material in a prism ballast design
with a toric back surface. This combination is what enables our toric lenses to perform at a higher level for
visual acuity and all-day comfort.

STABLE DESIGN  
FEATURES BENEFITS
  • Cast molded
  • High performance for consistent performance
  • Prism ballast design
  • Rapid stabilization 
  • Tapered edge
  • Minimal lower lid interaction for outstanding comfort
STABLE MATERIAL  
FEATURES BENEFITS
  • Biocompatible material - hioxifilcon D 
    made with GMA hydrogel copolymer
  • Rapid equilibration and sustained on-eye stability
  • Moisture control formula with
    advanced 
    hydration properties
  • Exceptional all-day comfort even for patients
    who have 
    end-of-day dryness
  • Dimensionally stable material unaffected
    by 
    changes in pH or temperature
  • Crisp, clear visual acuity with excellent low contrast
    sensitivity 
    for superior night vision
  • Group 2 high water non-ionic material
  • Resists unhealthy deposits keeping lenses clear and
    comfortable 
    over the entire wearing cycle
