NovaKone® custom soft lenses for Keratoconus

A custom approach to keratoconus, with the comfort of a soft lens.

Advanced design and flexible parameters help provide fitting control.

  • Central base curve designed for optical alignment over the steep central cornea
  • Variable lens center thickness to help neutralize irregular astigmatism
  • Independent, paracentral fitting curve to help ensure lens movement and physical fit

Lens Cross Section

A: Steep central base curve on posterior lens surface

Intended to match the average central K reading of the keratoconic eye.

B: Fitting curve designed like soft lens base curve

Helps ensure lens movement and fit.

C: Aspheric central optical section on anterior surface

Helps correct spherical aberration and provide a thinner lenticular flange.

D: Central lens thickness (index of thickness)

Helps manage different levels of corneal irregularity.

E: Front-surface cylinder optics

Corrects astigmatism up to -10.00D.

F: Dual Elliptical Stabilization

Aids in orientation and rotational stability.
