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—and straightforward fitting, 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. NovaKone lenses can be used in keratoconic patients who have had the cross-linking procedure for managing keratoconus progression.

This customized soft lens offers you and your patients:

  • The comfort of a soft lens
  • A straightforward fitting approach
  • The option of quarterly replacement

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™ and cylinder powers to -10.00D to help address residual astigmatism
  • An independent para-central fitting curve to help lens movement and physical fit


  • NovaKone soft lenses for keratoconus are indicated for visual correction for patients with keratoconus.
  • NovaKone is well-suited for cases where GP, hybrid, and scleral lenses 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 of a steep central base curve which is intended to match the average 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 ensure good lens movement and fit.

TThe anterior surface has an aspheric central optical section (C) to help correct spherical aberration, and 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.

Residual 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.
