Meriden Eye Care, LLC




Visionary Optics HydroKone™ offers a new approach to keratoconus that offers the comfort of a soft lens; custom parameters, including cylinder correction to -15.00 D; and 3 unique designs giving you more options to successfully fit all stages of keratoconus.

Standard Design offers a central steep zone and is great for mild to advanced keratoconus patients.

Globus Design offers a larger sagittal depth and is ideal for patients who have ectasia covering most of the cornea.

Pellucid Design is a reverse geometry that is great for patients who have ectasia in a large sector of the cornea.

  • A higher level of comfort than most corneal GP or hybrid lenses can deliver
  • Excellent visual outcomes
  • Ability to correct residual astigmatism up to -15.00 D with a double slab off prism ballasted design
