Why 3 Diameters?

 

27horizontalotl

 

 

 

Pacific University recently conducted a study on corneal diameter and findings indicate that
27% of contact lens fits fall outside the standard parameters and would benefit from a small or large diameter. 

  • 14% of patients have an HVID 11.3 and smaller
  • 13% of patients have an HVID 12.3 and larger

To further substantiate the above findings, we conducted our own clinical evaluation on HVID and comfort. In addition 
to patients falling outside standard parameters, we found that there were also comfort issues with these patients. 

  • Reported comfort issues from 37% of patients with HVID < 11.3
  • Reported comfort issues from 53% of patients with HVID > 12.3X-Cel rgb 72dpi

Why One Week?

 

Blondgirl

For patients who would benefit from a more frequent replacement, but don't want to incur the cost of a daily disposable.

  • Less deposits = less complications
  • Fewer dry eye related problems

A Replacement Schedule that Makes Sense

  • Weekly replacement is easy: start a new week - start a new lens
  • Supports patient compliance

Affordable

Study Results

dreamstime s 38853921 3 
A patient preference study was done to evaluate the performance of currently used frequent replacement lenses across 
three wearing modalites compared with Extreme H2O Weekly.

Patients rate the lenses in terms of comfort, dryness and vision.

  • 75% of Air Optix patients found Extreme H2O Weekly to be as good or better
  • 73% of Biofinity patients found Extreme H2O Weekly to be as good or better
  • 67% of patients rated Extreme H2O Weekly as good or better than their current two-week lens 
  • Patient preference was virtually equal between Acuvue Oasys and Extreme H2O Weekly
