Extreme H2O 54 Toric

LC - The lowest available cylinder: Designed for patients with astigmatism from 0.50D to 1.00D

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

Low cylinder patient requirements:

  • 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

*Clinical study conducted by Urs Businger, OD., FAAO, 2/07; data on file.

Mid cylinder patient requirements:

  • 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 

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
  • Moisture control formula with advanced hydration properties = Exceptional all-day comfort even for patients who have end-of-day dryness
  • Dimensional 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
 
  • 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.
