A Soft Contact Lens for Keratoconus.

If you’re looking for an approach to keratoconus with the comfort of a soft lens, but with custom parameters—including cylinder correction to -10.00D—NovaKone is it. NovaKone soft lenses can be a viable solution for many stages of keratoconus and are an alternative for patients who have failed to tolerate GPs or hybrids.

This customized soft lens offers you and your patients:

  • The comfort of a soft lens
  • The option of scheduled replacement as determined by an eye care practitioner

Designed For Keratoconus

NovaKone is designed specifically for the keratoconic eye, with advanced design features and flexible parameters that help provide fitting control.

  • A central base curve designed for optical alignment over the steep central cornea
  • Variable lens center thickness (IT Factor) to help neutralize irregular astigmatism
  • Dual Elliptical Stabilization
  • Cylinder powers to -10.00D to help address residual astigmatism
  • An independent para-central fitting curve to help lens movement and physical fit

Areas Of Use

  • NovaKone soft lenses for keratoconus are indicated for visual correction for patients with keratoconus.
  • NovaKone is well-suited for cases where corneal GPs or hybrids have not been tolerated or are otherwise contraindicated.
  • NovaKone offers soft lens comfort and another lens option in your armamentarium.

Lens Cross-Section

The posterior surface of the lens (A) includes a steep central base curve which is intended to match the average central K reading of the keratoconic eye.

The fitting curve (B) is similar in design to the base curve of a standard soft lens and is intended to help ensure lens movement and fit.

The anterior surface has an aspheric central optical section (C) to help correct spherical aberration and provide a thinner lenticular flange.

The IT (Index of Thickness) Factor describes the central thickness of the lens (D) and helps manage differing levels of corneal irregularity.

Astigmatism up to -10.00D is corrected by front surface cylinder optics. (E)

Dual Elliptical Stabilization (F) is employed to aid orientation and rotational stability.
