Description

Toric or inverse geometry GP lens with 4 fitting zones for stabilization or gradual toric peripheral fitting
In contact lens fitting, it’s known that when normal geometries do not succeed the desired stabilization or centration, inverse geometry is used (secondary curve, steeper that the base curve). The Epsilon PK 4 zones design comes to cover all those cases, integrating back and/or front toric correction.
Indications:
Post keratoplasty, corneal shapes with increased height differences at various quadrants, high toric anterior corneas
Available parameters:
Base curves: 7.00 to 9.60 in 0.10mm steps

Astigmatism: Up to 12.00D depending on the fitting modality

Toric periphery: 0.20 to 1.00 mm in 0.10 steps

Diopters: +40.00 to -35.00 in 0.25 D steps

Front toric optics : up to 6.00 D in 0.25 steps

Optics eccentricity: -0.70 to 0.70 in 0.05 steps

Diameters: 9.50 to 12.50 mm in 0.10 steps

Materials: High Dk 100, Medium Dk 50

It’s the first lens choice for cases succeeding penetrating keratoplasty, when a graft is positioned higher than the patient’s corneal shape.
In certain cases, diameters up to 12.50 mm are used to obtain better centration and optical correction.
