The elliptic geometry of Epsilon CORNEA 2 zones in conjunction with the toric periphery offers improved lens stabilization when vision is optimal but the fitter wishes better lens stabilization, in cases of corneal astigmatism greater than 1.50 D.
Indications:
Myopia, hyperopia, astigmatism up to 2.50 D, first and second stage of keratoconus
Available parameters:
Base curves: 7.00 to 8.60 mm in 0.10mm steps, aspheric
Toric periphery: 0.20 to 1.00 mm in 0.10 steps
Diopters: +25.00 to -35.00 in 0.25 D steps

Optics eccentricity: -0.70 to 0.70 in 0.05 steps
Diameters: 9.00 to 11.50 in 0.10 steps
Materials: High Dk 100, Medium Dk 50

The Epsilon CORNEA 2 zones can fulfill those cases where bicurve lenses provide acceptable vision in medium or high astigmatism, but not the required stability due to the back zone alignment or toric periphery requirement.  Additionally, there are indicated cases where the periphery of the lens is protruding from the cornea, increasing the lid awareness.
