Swiss-made RGP lens designed specifically for keratoconus — empirically fitted from topography and any trial RGP lens, covering a wide range of cone severity and location.
The Excellent-KK from Appenzeller Kontaktlinsen is a reverse-geometry RGP lens designed for keratoconus. Its unique geometry allows empirical fitting using corneal topography and any standard trial RGP lens — no specialist keratoconus diagnostic set required.
Suitable for mild to advanced keratoconus across a wide range of cone locations. CE Marked and Swiss Made — the reliable workhorse keratoconus RGP for practitioners who want consistent results.
Early inferior steepening. Excellent-KK provides stable vision where spectacles are beginning to fail.
Defined cone ~45–50D. Empirical fitting from topography alone — no specialist diagnostic set needed.
Pronounced apex >52D. Reverse-geometry design vaults the cone comfortably across all locations.
Significant cone severity. High Dk material maintains corneal health even in the most advanced cases.
Fitted empirically from corneal topography and any standard trial RGP — no keratoconus-specific diagnostic set required.
