GP lens with toric optic zone and peripheral curve
First choice of GP lens when corneal astigmatism exceeds 2.50 D. The combination of gradual toricity of the optic and fitting zone, offers stable vision and fit, even if astigmatism is over 4.00 D.
Indicated for cases with astigmatism of 2.00 to 9.00 D and in post graft cases
Base curves: 7.00 to 8.60 mm in 0.10mm steps, aspheric
Diopters: +30.00 to -35.00 in 0.25 D steps
Diameters: 9.80 mm (Additional parameters available)
Astigmatism: Up to 12.00D depending on the fitting modality
Geometry: Two curve toric aspheric
Materials: Optimum Extreme Dk 125, Optimum Extra Dk 100, Boston XO Dk 100, Paragon FSA 52
TORIC ASPHERIC lens geometry is a two-curve toric aspheric lens. It’s customized depending on the fitting requirements. This specific lens is chosen when corneal astigmatism is more than 2.50 D (If astigmatism is lower, Beta Toric can be fitted).
