Perfecting vision with precision

in disposable contact lenses

Size matters when fitting contact lenses


Most disposable contact lens manufacturers determine the base curve and diameter of their lenses based on the average HVID of 11.8.  The unfortunate reality is that 27% – more than one in every four patients you see – have an HVID that falls outside the normal range of 11.3 to 12.3 mm. Putting these patients in an average size lens is not going to provide them with the contact lens comfort they want.  This may also contribute to the steady drop out rate we have seen over the past 25 years.

Don’t settle for a one size fit’s all contact lens.  Extreme H2O is available in a small and large diameters enabling you to give 100% of your patients the contact lens comfort and vision they expect.

Advanced contact lenses

Clerio’s LIRIC technology will offer superior Fresnel lens diffractive optics patterns to correct presbyopia, myopia, hyperopia, astigmatism and higher-order aberrations.  Using a femtosecond laser to induce refractive index change, LIRIC offers a safer, flexible and new vision correction solution to a broad patient population.  

What does this mean?

  • Better stability of optical performance: Vision is not degraded from blinking, which causes lens movement
  • Better performance in low light: Vision is not degraded in low light conditions due to changes in pupil size
  • Easier for clinicians to prescribe: Can be prescribed directly based on patient’s actual ADD power
  • No compromises: Users can continue wearing contacts with the onset of presbyopia while maintaining the same spectacle-corrected vision users have become accustomed 

Clerio is working on its first multifocal contact lens, to be launched  in 2022, which offers no compromise in distance vision.
