A Breakthrough Soft Lens for Keratoconus.
If you’re looking for a new approach to keratoconus that offers the comfort of a soft lens; custom parameters, including cylinder correction to -10.00D; and the kind of straightforward fitting not found in hybrids, Alden Optical’s new NovaKone™ soft lens for keratoconus is it. While NovaKone lenses can be a viable solution for all stages of keratoconus, they’re especially effective for patients with more advanced conditions, those who have failed to tolerate GPs, or who have been unsuccessful with hybrid and scleral lenses.
This remarkable new lens offers you and your patients:
- A higher level of comfort than most GP or hybrid lenses can deliver
- Excellent visual outcomes
- A straightforward fitting approach
- The option of quarterly replacement
Designed For Success.
NovaKone is designed specifically for the keratoconic eye, with advanced design features and flexible parameters that give you incredibly precise fitting control.
- A central base curve optimized for precise optical alignment over the steep central cornea
- Variable lens center thickness (IT Factor) to neutralize almost any irregular astigmatism
- Our proprietary Dual Elliptical Stabilization™ and cylinder powers to -10.00D to precisely address residual astigmatism
- An independent para-central fitting curve to assure excellent lens movement and physical fit
Indications
- NovaKone soft lenses for keratoconus are indicated for visual correction for patients with all stages of keratoconus and pellucid marginal degeneration.
- NovaKone can be particularly successful to address cases where GP, hybrid, and scleral lenses have failed or are otherwise contraindicated.
- NovaKone offers extraordinary comfort and can be an excellent adjunct to other forms of correction.

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.
The anterior surface has an aspheric central optical section (C) to correct spherical aberration, and a thinner lenticular flange to maximize oxygen permeability.
The IT (index of thickness) Factor describes the central thickness of the lens (D) and effectively manages 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 ensure excellent orientation and rotational stability.
