Extreme H2O - Model H2O 54 Toric - Lens

• Designed for the 55% of patients with astigmatism from 0.50D to 1.00D
• More than 90% of patients were fit with the first lens selected*
• Patients attained a full line of improvement vs. spherical correction
• A cost effective upgrade from spheres or aspheres for low astigmatic patients

• Axis available in 10º increments to meet the more precise axis requirements of a mid cyl correction
• Designed for the 21% of patients with astigmatism from 1.00D to 1.50D
• Combination of stable design and stable material provide exceptional on-eye stability

• Biocompatible material, hioxifilcon D made with GMA/HEMA copolymer provides rapid equilibration and sustained on-eye stability.
• Moisture controlled formula with advanced hydrations properties gives patients exceptional all-day comfort – even for those who have end-of-day dryness issues. 
• Dimensionally stable material unaffected by changes in pH or temperature enables 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 the entire wearing cycle.

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

• Cast molded = high performance for consistent performance
• Prism ballast design – rapid stabilization
• Tapered edge = minimal lower lid interaction for outstanding comfort

STABLE MATERIAL

• Bio compatible material – Hioxifilcon D – made with GMA hydrogel copolyer = Rapid equilibration and sustained on-eye stability
