Soft lens with inverse geometry, for flattened corneal shapes, following PK, PRK, LASIK
The soft lens design which solves the decentration issues of the ablated cornea. Because of the inverse geometry (periphery steeper than the center) and the customization that can be ordered, it fits in any centrally flattened cornea.
Myopia, hyperopia, in cases when standard lens geometries do not fit correctly. (post-refractive surgery, post transplanted, post traumatic)
Base curves: Medium: Refraction before surgery up to -6.00 D, High: Refraction before surgery > -6.00 D
Diopters: +25.00 to -30.00 in 0.25 D steps
Diameter: 14.50 mm (Additional diameters available)
Optical zone: 8.00 mm at -3.00 D
Optical design: Aspheric
Fitting: Inverse geometry
Material: GM Advance 49%, 42% HEMA
LAMDA lens will satisfy any case that cannot be fitted with the ALPHA lens. Indicated when refraction is spherical.
